Case Study Formal And Informal Assessments Education Essay

Case Study Formal And Informal Assessments Education Essay Formal and informal assessments are two specific procedures that teachers use to evaluate and grade their students. Both formal and informal formative assessments involve gathering, interpreting, and acting on information (Ruiz-Primo Furtak,2004, p. 4). Formal assessments are standardized exams used by a state to reflect on particular grade level to measure a students academic abilities. These exams are administered in the same way every time with a time restriction and instructions to how the exam should be graded. In contrast, informal assessments are exams or activities designed to specially review or test students knowledge on a certain academic subject taught by their teacher. I will be discussing the advantage and disadvantage for two different forms of formal assessment and four types of informal assessments methods. The two formal assessments are norm-referenced and criterion-referenced. Norm-referenced are standardized tests and are linked to inter individual differences (Gargiulo, 2008, p.65). This test compares the students skill to other students in the similar age group. Statistical method is used to determine how the student did. For example first grade students were tested and the outcome is used in a statistical method. You would be able to see how each student ranked. For example, Jon scored at the 50th percentile among his class. There are advantages and disadvantages in using norm referenced testing. One advantage to this method is it can determine whether a student may need special services. For example, if the student scores less than standard norm for reading, they will receive special services to aid them in this subject. Another advantage to this method is it allows parents to see how their childs academic results are compared to their peers. For example, Julie performs at 86 percentile in her class. This means that Julie performed better than 86% from her classmates. As there are advantages, there are disadvantages. One disadvantage to this method is it consists of broad academic information and may not consist of current classroom content. Another disadvantage is it does not fully capture a students academic abilities on problem solving, decision making, social skills, nor their ability elaborate on certain topic. In contrast, Criterion-referenced tests are associated with intra individual differences and can provide data that is useful for instructional planning (Gargiulo, 2008, p.66). For example, a math problem is given to a student to see if the student is able to add two digit numbers. The outcome is strictly based on whether the student did or did not answer the problem correctly. The first advantage to this test is it can compare a students individual performance from their previous one. For example, Aprils current test indicated her reading skills have improved from last quarter. Aprils results are not compared to how well she did among her classmates instead it compares to her individual progress. Another advantage to this test it can assist a teacher to figure out each students academic strengths and weakness. A teacher can guide and assign additional help in the areas where students need improvement. The downfall to this method is it cannot compare student academic performance to ot her schools or districts. For example, a teacher will not be able to compare her students success to other classes nor to other schools. Another disadvantage is creating a valid exam for students. Designing an exam needs to meet specific standards plus its time consuming for teachers to work around their daily responsibilities. The following are the four types of informal assessments that can be used in a classroom which are an essay exam, a classroom game, walk around method, and a multiple choice exam. The first informal assessment is an essay exam. Essay exams are questions based on a certain lesson or topic where a student needs to provide a written answer. Depending on the exam instructions students may only need to write a couple of paragraphs or several pages in length. The following are two advantages in using an essay exam to test students. First, students have the opportunity to express their thoughts and demonstrate their level of comprehension on a certain question. The second advantage, students begin to construct and analyze how to answer each question. For example, the instruction on the essay says to please explain the difference between a mammal and an amphibian. The student first needs to analyze the differences between the two species and then construct examples to elaborate on the question. An issue does represent itself; this type of method is time consuming for both the student and teacher. The students need plenty of time to answer and write an essay and the te acher needs time to evaluate and grade each paper. The second disadvantage, teachers must be aware of their biases when writing a question where students need to agree or disagree on a certain topic. This disadvantage may get in the way of grading papers accurately. A teacher needs to be aware of their bias and base their grading on the students response not if they agree or disagree with their student. Another informal way to evaluate a students progress is a classroom game. A Classroom game creates an opportunity for students to apply their knowledge and encourages them to learn. For example, the class is divided into four groups to play a game of Jeopardy. The game of Jeopardy consists of questions on a certain academic subject. An advantage to this method is it promotes cooperative learning. Students are learning how to interact, collaborate, and work together with their peers to answer questions. Working together provides positive reinforcements for students to develop social skills and trust among their team members. Another advantage it motivates students to apply their own knowledge and retain new information as they play the game. A game will keep students alert and encourages participation which will lead to learning. Since students are divided into groups not every student is participating or collaborating on every question and this is downfall to this method. Even though each student has an opportunity to answer a question, the group is judged as a whole not the individual knowledge to every question but the ones they answer. Another disadvantage to this method does not provide enough feedback to a teacher to determine which students needs additional assistance in comprehending the current subject. The third informal assessment is the walk-around. This assessment requires the teacher to interact with each student as they work together as a group or individually. The teacher is actively observing and assisting students to stay on task. The advantage to this method it allows the teacher to interact with students individually or as a group to answer any concerns or assist them in understanding their assignment. The second advantage is the one on one conference. The teacher uses the one on one conference to talk to the students for five or ten minutes. This conference offers attention, and additional help in instructions for students(Cole,1999,p.4). This type of interaction builds trust and improves the communication between teacher and student. A downside to walk around assessment is giving each student or groups the same amount of time to answer questions or concerns. Since every student or groups have different questions, some may need additional assistance than others. This may cause some behavior issues or delay some students in completing their assignment. Another issue is making sure every student understands the material or contributing their work to their group. The teacher needs to give every student an opportunity to talk and demonstrate they understand the assignment. Lastly, the multiple-choice test is another assessment used in a classroom. Multiple choice tests consist of questions and a list of possible answers for each question. An upside to this method students begin to access their knowledge and apply it to every question by eliminating misleading choices. This method is also an advantage for teachers as well. The grading is less time consuming than other methods and easier to narrow down where the students are having difficulties. A disadvantage for students is it may cause them some confusion or frustration when the exams are poorly written. Poor written exams consist of tricky options to choose from, for instance having two possible answers. The second disadvantage for students is not being able to understand a question. This may lead the students to guess on answers they are not able to comprehend due to reading difficulties or a poor written exam. This may lead to inappropriate score on the students progress or knowledge. In conclusion, both formal and informal assessments consist of advantages and disadvantages that a teacher should consider and understand before administrating these assessments. Assessments are necessary to pinpoint students academic strengths and weaknesses. This allows a teacher to provide additional assistance to students that are struggling. Without assessments teachers will not be able to properly evaluate and assist students.

The Hidden Key to E-Commerce Success

In fact, it took Amazon. com only one quarter after adding music to its offerings to become the N et’s leading music seller. The company currently is targeting the $150 billion pharmaceuticals market with a 40-percent stake in Drugstore. com. Today, the emphasis among more mature Web retailers like Amazon. com is shifting from marketing to fulfillment logistics—what happens after the rder is placed. Good fulfillment—taking the right product, putting it in the right box, shipping it, and gaining the customer’s approval on arrival—is a demanding task. We believe it is here—in the down-and-dirty details of consumer direct order fulfillment—that the epic battles for domination of the e-Commerce marketplace will ultimately be won or lost. The emergence of the e-Supply chain, a group of strategically aligned companies focused on delivering differentiable value, signals a shift in the nature of online competition.It involves rethinking traditional supplier relationships and the role of informationdriven fulfillment logistics. In the new network economy, establishing a sustainable e-Commerce position is as much about using the right fulfillment strategies to get your products or services to buyers as it is about having the right product at the right price. The key to success is being able to give customers what they want, Fall 1999 Illustration by Roger Roth when they want it, and how they want it—all at the lowest cost. That requires â€Å"real-time fulfillment† solutions.These rising demands have driven a three-phase evolution. First the e-Corporation, which focuses on creating and maximizing the potential of internal supply chains, evolves into e-Business communities, where distributors, suppliers, customers, and others are linked but not fully integrated. These communities then become the e-Supply chain, which requires business-process and technology synchronization across the entire chain. (Exhibit 1 depicts this progression. ) Unfortunately, much of the start-up planning for e-Commerce ventures a pplies old models to new enterprises.It assumes, for example, the existence of a brick-and-mortar support infrastructure for the fulfillment or the spontaneous development of that infrastructure. Like it or not, most e-Commerce retailers place their initial emphasis on the â€Å"exciting† areas: Web product development, traffic generation, dynamic or customized Web pages, transactions, and so on. Often, e-Commerce retailers give little thought to order fulfillment and distribution—a capability critical to the success or failure of Web commerce. Our research shows that the lack of an Fall 1999 ntegrated supply chain infrastructure or weaknesses in integrating multiparty logistics components can undermine the benefits of e-Commerce and hinder innovative responses to the competition. The e-Fulfillment Opportunity The Internet offers a rich new opportunity for direct consumer access, but it also raises new challenges. Web retailers find product fulfillment—picking a nd packing in very small quantities and shipping via parcel carriers—a particularly difficult activity. It often requires relying on third-party fulfillment vendors (a concept discussed later in this article) to do the job.But collaboration in fulfillment chains is no longer confined to conventional two-company alliances, such as between shipper and a logistics services provider. Today, groups of enterprises are banding together for a common purpose—to satisfy customer demand. A new form of competition is emerging: e-Supply chain vs. e-Supply chain. In the Internet book retailing war, for example, the competition is not only between Amazon. com and Barnes & Noble but also among groups of companies that make up the e-Supply chain anchored by each company. An e-Supply chain is, in effect, a virtual organizaSupply Chain Management Review 61ORDER FULFILLMENT process. ) Vendors could work within specified routing guidelines and still tender for trucks online in conjunction with other geographically close vendors to get full-truckload rates. Internet start-ups have the luxury of starting from scratch and defining their fulfillment infrastructure Business Process and Technology specifically for the products Integration being offered online. This is not the case for established Phase 3 E-Supply Chain companies like catalog companies or store-based retailers such as Wal-Mart, Borders, and JCPenney.These companies already have fulfillment and distribution networks designed to ship a variety of products in bulk quantities to hundreds of stores. They realize that they cannot layer home delivery on the existing infrastructure. The established companies must decide whether to extend their existing facilities for consumer-direct eCommerce or build a new set of fulfillment facilities tailored to low volumes and high-variety product mixes. The enlightened ones realize that they need to invent a new customer-driven fulfillment model that can extract enough costs o ut of the current model to justify home delivery costs.That new model, we believe, is an intercompany order-fulfillment and replenishment model. It utilizes business process synchronization to eliminate redundant processes among supply chain trading companies and to improve information sharing— doing away with excess labor, inventory, and holding costs. The design and implementation of such a coordinated and synchronized fulfillment infrastructure poses a major managerial problem. To shed light on this problem and provide a prescriptive roadmap, we address the following questions: What is the impact of current customer-direct business models on fulfillment strategies?What is the definition of consumer-direct fulfillment logistics? Why is having a consumer-direct model so important? What types of fulfillment strategies are currently employed in e-Commerce? What strategic business-process reengineering and synchronization steps can managers take when designing a consumer-direct fulfillment logistics strategy? Fall 1999 EXHIBIT 1 Evolution of the Network Economy Distributors Suppliers Internal Supply Chain Reengineering External Linkages Customers Phase 1 E-Corporation Logistics Providers Phase 2 E-Business Communities ion that encompasses a group of trading companies, all working together to slash costs and share profits. By optimizing not only their internal processes but also their mutual interactions, they realize the benefits of a truly integrated supply chain. This concept—business-process and supply chain synchronization—lays the basis for the next revolution in supply chain management. It takes supply chain integration to a new level of efficiency by requiring companies to focus on synchronizing business processes around standard interface points and upgrading these points as the industry evolves.Synchronization of these â€Å"touch points† eliminates costs associated with inefficient movement of goods, redundant processes, and excess inventory. In doing so, it promotes a dedicated collaboration of all supply chain trading partners—suppliers, manufacturers, distributors, wholesalers, thirdparty providers, transportation companies, and retailers. Through e-Commerce, redundant processes among trading partners (such as multiple accuracy audits, receiving-dock appointments, and inventory planning activities) can be eliminated.The immediacy and availability of the Internet, once security and data cleansing issues are worked out, fulfills the promise of true synchronization. To take just a few examples, if vendors can gain access to a publicly available schedule on the Internet and book their own receiving appointments, they no longer need to send requests for appointments and wait for responses. Retailers would not need to research late payments if their customers could download payment status directly from the retailer’s Web site. (At least two major retailers have already begun this 62 Supply C hain Management ReviewThe Logistics of Consumer-Direct Fulfillment Three forces are converging to create an explosion in consumer-direct business models: technology forces are making it possible, market forces are making it viable, and social forces are making it inevitable. Keep in mind, though, that consumers demand more than an interactive experience. They want delivery convenience and lower fulfillment costs. They need to be assured of fast and reliable delivery. The value the consumer places on timely delivery can affect the logistics network design significantly. Time is money,† and digital consumers of the 21st century don’t have the same tolerance levels as their analog-world ancestors. Today’s consumers are yearning for instant gratification as never before. Partners in the supply chain must improve their efficiencies—from order capture to fulfillment— to provide that gratification. The goal of consumer-direct business models is to let cust omers select and configure products and services interactively, get a price quote, and receive a committed delivery date online.Companies serious about satisfying customers online must substantially change their process to make consumer-direct retailing and manufacturing attractive to the consumer. Companies must re-evaluate the complete fulfillment business model—promotions, merchandising, product selection, pricing, supplier relations, technical management, distribution, returns, and post-sale service. Each of these areas demands new processes, skills, and approaches. To satisfy a consumer-driven marketplace, companies must move beyond the singular mentality of intracompany optimization.Instead, they must focus on how intercompany business process synchronization can transform consumer demands into consumer satisfaction. As with a single company, core competencies of each component of the virtual organization must be evaluated objectively to eliminate inefficiencies. Manage rs of that virtual organization will continue to reengineer best practices, while at the same time: Building replenishment programs based on consumers â€Å"pulling† the product through the supply chain from the manufacturer. Employing new forecasting methods that reflect total pipeline visibility.Investing collectively in technology and equipment to capitalize on market opportunities. The success of consumer direct fulfillment logistics models depends on the successful integration of Fall 1999 four key elements: order-fulfillment planning, product execution, distribution management, and crossapplication integration. 1. Order-Fulfillment Planning. Rising customer expectations and short fulfillment deadlines call for effective planning that breaks artificial boundaries and bridges the gaps between the consumer and the other players in the supply chain.Fulfillment planning must consider the entire planning process— from manufacturing, through distribution and transportat ion—within a single integrated model. Fulfillment planning involves evaluation of multiple planning strategies such as: Establishing a sustainable e-Commerce position is as Profitable-to-promise: Should I take the customer order at this time? Available-to-promise: Is inventory available to fulfill the order? Capable-to-promise: Does manufacturing capacity allow order commitment?Select the plan that best meets the desired customer-service levels considering transportation and manufacturing constraints. It’s important to plan backwards from customer priorities and fulfillment deadlines. Thus, to generate a feasible plan, the fulfillment-planning process needs to consider all supply chain constraints simultaneously. These include transportation constraints such as truck capacity and weight, use of alternate modes, and availability of downstream resources such as loading docks. 1 2. Production Execution.With the advent of modular designs, more and more production functions are being performed at dedicated warehouses and distribution centers. The typical activities include light subassembly and sequencing, kitting, merging, consolidation, packaging, and labeling. Timing of the final assembly often drives the production plan for subassemblies. The process starts with the master production schedule for the finished product. An MRP (Manufacturing Resource Planning) system explodes this schedule to derive when, where, and in what quantities various subassemblies and components are required to make each product.Production also includes componentreplenishment strategies that minimize the amount of inventory in the pipeline and coordinate product Supply Chain Management Review 63 much about using the right order-fulfillment strategies as it is about having the right product at the right price. ORDER FULFILLMENT hand-offs between the various parties involved. Timely replenishment of warehouses is critical because customers will no longer tolerate out-ofstock situations. 3. Distribution Management.Distribution management encompasses the entire process of transporting goods from manufacturer to distribution centers and then to final consumption point. The process also may include packing, document preparation, customs brokerage, and inventory and warehouse management. One of the most important innovations here is the integration of distribution with transportation planning and scheduling through a comprehensive supply can address by utilizing standardized information formats and communication points between trading partners.Distribution center inventory has to be integrated effectively with the customer contact system. In high-velocity retail settings like the Web, customers quickly become unhappy if the seller is out of stock for what is advertised as in stock. Accurate distribution center inventory, updated frequently, is essential to running an effective online business. A Framework for e-Commerce Fulfillment Strategies In the face of increasing competition, absence of pricing power, and shrinking operating margins, companies will succeed or fail based on the efficiency of their fulfillment strategies.Business analysts often focus on the number of orders a company generates on the Web as an indicator of its competitive strength. But a more accurate measure may be the company’s process for rapidly and efficiently translating the orders into fill-rates that satisfy and exceed customer expectations. This section presents a framework of evolving fulfillment strategies. It then illustrates that framework with a wide array of examples and derives implications and guidelines for management. The framework is based on two dimensions: the structure and the operation of fulfillment strategies.On the structure dimension, the strategies are classified as either centralized or distributed. In a centralized structure, all warehousing, pickup, packing, and shipping are operated in a central site, usually a distribution or logistics center. In a distributed structure, warehousing, pickup, packing, and shipping or delivery are located at different sites. On the operation dimension, the fulfillment strategies are either self-operated if the fulfillment process is operated by the company itself or outsourced if it is done by third parties or partners.All of these strategies, discussed below, have trade-offs regarding investment, inventory costs, and operational complexity. Strategy A. Distributed Delivery Centers Fulfillment through distributed delivery centers is an acceptable approach for companies that are just getting online or for those that have a delivery funcFall 1999 â€Å"Time is money,† chain execution solution. Transportation-management software spans the life cycle of the shipment and allows customers to view all of their shipments across a network of multimodal transportation providers. Distribution anagement also means providing users with easy access to shipping, tracking, and del ivery data. Reverse logistics is another function of distribution management. Faster product obsolescence and more generous warranties have escalated the number of returns. Reverse logistics not only encompasses damaged or returned goods but also products designed for remanufacture, hazardous materials, and reusable packaging. 4. Cross-Application Integration. To be effective, companies need to seamlessly integrate the three elements of fulfillment logistics described above.At present, this rarely happens. Most Web servers only have a sporadic connection to the Enterprise Resource Planning (ERP) system like SAP’s R/3, which controls accounting, production, materials management, and distribution. Thus, when the user wants to know when a product will be delivered, the Web application often cannot tell that user what inventory is available in the ERP system or at the third-party warehouse. These are precisely the kinds of problems that business-process synchronization 64 Supply Chain Management Review nd digital consumers of the 21st century don’t have the same tolerance levels as their analog-world ancestors. tion in their stores. This approach minimizes the upfront investment and can be set up quickly. It also facilitates strategies such as â€Å"Buy Here/Pick Up There. † This strategy allows consumers to place an order by phone or online at one store location and pick up the merchandise at another. Though distributed delivery centers do have their advantages (like the obvious reduction in shipping costs), they also can experience certain difficulties.For one thing, controlling inventory for every center at an appropriate level may result in operational complexity and incur expensive inventory costs. In addition, in-store employees often are unfamiliar with warehouse picking and packing procedures. Further, high employee turnover can make picking and packing quality standards difficult to maintain. Yet another problem is scheduling. To mini mize conflict with customers who are shopping during the daytime, picking operations often are scheduled for off-peak shopping hours.Although this may appear to be an efficient use of resources, the delayed picking may force an additional day into the delivery cycle, since carrier pickups may take place before the completion of the current day’s picking and packing activities. Strategy B. Partner Fulfillment Operations Some online retailers are using the partner fulfillment model, which means they have no inventory, no shops, and no product brands. Fulfillment is performed entirely by partners. This approach has clear advantages from the standpoint of inventory-carrying costs. But there are some disadvantages as well.This has been evident in the experience of Peapod, an online grocery retailer that provides online shopping and home delivery services. Peapod discovered that its initial strategy of partnering with local supermarkets for fulfillment meant charging consumers high delivery costs of up to $16 an order. This pricing level made it virtually impossible to build a customer base. To attract more customers, the company has begun to dismantle some of its partnerships and move toward a distributed-delivery fulfillment model by establishing its own warehouses in selected markets.The introduction of a distributed-delivery model, however, has put a strain on the company’s financial growth. Peapod management estimates that each new distribution center requires a capital expenditure of roughly $1. 5 million plus operating expenses. Peapod expects a net loss at each facility during the first 12 to 18 months of operation. In the long run, however, the new centers should give the company higher overall margins as well as greater operating efficiencies. Fall 1999 Companies will succeed or fail based on the efficiency of their fulfillment strategies.Strategy C. Dedicated Fulfillment Center Today, many online retailers have established their own dedicate d fulfillment centers. These players include Amazon. com, BarnesandNoble. com, Dell Computer, Micro Warehouse, and Insight Enterprises. This approach is well suited to the book and computer industry, where the fulfillment centers can facilitate prompt delivery. The dedicated fulfillment center model reduces delivery costs for low-margin items. Using this approach, companies can measure expected delivery time in hours—not days.The tradeoffs of this approach are: Low or unpredictable sales volumes. This will result in high inventory-carrying costs. High up-front investment. Depending upon its warehouse setup and flexibility, a distribution fulfillment center can incur high costs. It may, for example, require major systems modifications, automated warehouses, and conveyors. This option, moreover, can add operational complexity to the product and information flows. Yet even though this approach increases the up-front capital investment, it can reduce long-term operating costs.Dec reased flexibility. The operation’s scalability is restricted to the existing warehouse infrastructure. This may make it difficult to meet the variability in demand inherent in some retail segments. Strategy D. Third-Party Fulfillment Centers (â€Å"Virtual Warehousing†) As companies struggle to manage unpredictable demand better, they are turning toward third-party fulfillment centers (3PFs), which can be thought of as virtual warehouses. Through this approach, companies can lease the skills and facilities needed for order fulfillment rather than owning them.Third-party fulfillment companies offer flexibility in accommodating wide swings in demand over short periods. They also help facilitate inventoryreduction initiatives such as just-in-time programs. Another advantage of 3PF is the limited changes that must be made to legacy information systems. This option provides a much more robust capability than in-store fulfillment and minimizes operational impact. It also co nverts much of fulfillment into a variable cost offset by eliminating warehouse and Supply Chain Management Review 65 ORDER FULFILLMENT store costs associated with the sale of the product.This strategy allows retailers to leverage their buying power and extend product selection into lines not currently offered in their stores. The primary drawback of 3PF is few existing national fulfillment companies can accommodate a wide range of products. Even more problematical, ceding control of this critical aspect of the business represents a major paradigm shift for retailers. Depending upon the service levels required by customers, multiple fulfillment centers may be necessary to minimize delivery time—and this increases costs and required stock levels. y clear that customers don’t just buy products; instead, they buy the â€Å"service envelope. † They are looking to enter into a complex relationship with the selling company. Given the new reality, companies do not crea te value for customers by merely offering varieties of products. Rather, they must devise a logistics fulfillment strategy that envelops the product and meets customer needs such as convenience, reliability, and support. The choice of a fulfillment strategy depends on whether a company elects to compete essentially on customer responsiveness or operating excellence.In either case, the fulfillment strategy must support the overall business strategy. To ensure that this happens, a company needs to complete the following steps: (1) assess the competitive environment, (2) select the fulfillment strategy, (3) achieve business-process synchronization, and (4) design and implement the necessary cross-application integration. Importantly, the fulfillment strategy must take full advantage of new planning, warehousing, and transportation technologies that can cut order fill times dramatically.Assess the Competitive Environment The first step in fulfillment-logistics design is assessmentâ€⠀that is, identifying the opportunities, strengths, and weaknesses that will influence overall performance and viability of the fulfillment strategy. During the assessment phase, a company must gather information on the competitive environment across these strategic variables: Effectiveness. What are customers’ priorities and how are they changing? How closely does the overall design address the stated and unstated requirements of customers?Consider likely changes in buying patterns, potential competitors, long-run cost pressures, and new technologies. Value differentiation. Why do my customers buy from me? What makes my value proposition unique compared to the competition? Do customers appreciate the value in my offering and can this be leveraged into differentiated pricing strategies? The first step toward value differentiation is to map your customer’s entire experience with your product or service. Do this for each important customer segment. Capital intensity. Sh ould we choose a capitalintensive, high fixed-cost strategy?Or a less capital-intensive, flexible strategy? The e-Commerce impact on working capital outlay differs from retailer to retailer. It depends on such factors as the existing logistical infrastructure (dispersion of warehouses, existing product flow, etc. ), the Fall 1999 Effective fulfillment strategy is dynamic, using multiple channels simultaneously to reach important customers. Strategy E. Build-to-Order The customized build-to-order model is an emerging fulfillment center strategy that extends beyond the traditional framework and adopts an integrating or boundary-spanning perspective.Companies working to coordinate build-to-order fulfillment logistics strategies need to: Synchronize and manage the entire flow of materials through a complex network of resources in their supply chains as opposed to simply managing inventory in warehouses. Turn their attention to maximizing the throughput, rather than focus on controlling fixed costs. Alter the material flow upstream quickly and proactively as demand and product mix change, rather than react to changes in customer demand at the end of the process.A fundamental requirement of fulfillment logistics is the dedicated collaboration of all supply chain trading partners to eliminate the costs associated with inefficient movement of goods, redundant processes, and excess inventory. Effective collaboration not only ensures that the order flows through smoothly but also provides two crucial capabilities: the ability to adapt to increasingly frequent changes in consumer tastes and e-Commerce technology and the ability to improve processes continuously.Designing the Right Fulfillment Strategy Design of the fulfillment strategy is central to the overall corporate strategy.

Fall 1999 Supply Chain Management Review 67 ORDER FULFILLMENT in its purest form, gives rise to the virtual organization in which all trading companies work together as one competitive supply chain entity—the e-Supply chain. In the virtual organization, each trading company shares its information and resources, which results in better planning and more efficient product movement.In making business-process synchronization a reality, companies typically will encounter these challenges: Design and Implement Cross-Application Integration Among the key objectives of intercompany collaboration are more sophisticated distribution services, such as frequent inventory replenishments, more customized packing of goods to reduce unpacking times, more creative packaging and labeling of goods to meet merchandising strategies, and more effective exchange of trading information in compliance with EDI standards.Achievement of these objectives demands an increased use of cross-application integration. Superior application integration in a supply chain is central to achievi ng superior fulfillment productivity and speed. An effective fulfillment-management system must have the ability to integrate with: 1. Integrated enterprise applications. Included here are the ERP systems that integrate the inventory management, marketing, and financial functions. 2. Integrated interenterprise systems. These are the supply chain management systems for transportation, order management, warehouse management, and demand planning.For instance, FedEx has integrated its logistics and transportation capabilities with the SAP R/3 system. For R/3 users, the solution will simplify every related process step from order entry through shipment and tracking by tightly integrating with FedEx. For FedEx, this capability creates a competitive barrier that other carriers have to overcome. 3. Distribution center management and warehouse management systems. Included among these solutions are facility management systems. Efficient management of a distribution center operation now requir es collecting information on customer orders, inbound shipments, products vailable on-site, storage locations, product weights and sizes, and outbound shipping data (including customer-specific shipping requirements, routing data, and carrier requirements). This information must be analyzed dynamically to determine the most efficient use of the distribution center’s labor, materials-handling equipment, and shipping and receiving areas. Today’s information technology revolution does not merely support new order-fulfillment strategies, it creates them. Technology Challenge. Intercompany businessprocess synchronization requires sophisticated technology applications.It can be difficult, however, to identify those systems that truly support this initiative. The Data-Sharing Challenge. Supply chain systems not only need to communicate with one another but also to integrate their business practice knowledge into each trading company’s business logic. The companies must work quickly and painlessly to integrate their trading partners’ knowledge into their own business applications. The Adaptability Challenge. All the information in the world cannot help if trading companies don’t have the flexibility to alter business processes as consumer demands change.In this regard, all trading companies face similar challenges. For instance, when UPS issues a rate update, thousands of customers must implement these changes by a specified date and time. Companies need to implement business systems that can be upgraded easily to move with the market. The Standardization and Compliance Challenge. When one major player in the supply chain decides to upgrade to a new technology or adopt a new technical functionality, the other players are challenged to synchronize accordingly.When there are thousands of â€Å"touch points,† or interface points, the challenge can become enormously complex. In a perfect world, all trading partners would migrate i n unison to the latest technologies to realize the maximum benefit. But it is not likely that an entire supply chain can or will do this at once. Thus, it is important to focus on synchronizing business processes around these touch points and upgrading them as the market evolves. 68 Supply Chain Management Review Acting in Unison for the Consumer Order fulfillment and replenishment is a core business process. What makes onsumer-direct eCommerce compelling to customers is not just the online shopping experience but on-time delivery, fewer fulfillment errors, extra service, and convenience. These are the things that customers value. When companies fall short in responding to those values, they risk alienating or losing customers as a result. Fall 1999 ORDER FULFILLMENT Many potential e-Commerce participants have underestimated the difficulty and importance of the fulfillment side of this market arena. They see fulfillment and distribution logistics as peripheral to their competitive s trategy.Companies need to recognize that such benign neglect is risky and wastes opportunities for competitive advantage. In response to pressures from powerful market trends and technological changes, they must inspect past practices, channel commitments, and vendor relationships vigorously. Effective fulfillment strategy is dynamic, using multiple channels simultaneously to reach important customers. Today’s information technology revolution does not merely support new fulfillment strategies, it creates them. Consumers interface with technology daily, raising the bar on what is expected on the fulfillment side.Meeting these rising expectations requires a conscious shift in fulfillment strategies and a technological infrastructure that ties together every aspect of the consumer-direct â€Å"fulfillment chain. † Interenterprise business-process synchronization is a key to success in this emerging real-time marketplace. Deep information exchange among supply chain partn ers brings opportunities to develop interenterprise strategies that become new sources of competitive advantage. Information integration allows companies to monitor daily trends, market conditions, product acquisitions, and planning functions.To achieve operational integration, manufacturers, distributors, and retailers must exchange information effectively with other supply chain participants at key interface â€Å"touch points. † Importantly, this includes providing real-time information to customers so they know the status of their order at any given moment. When all trading partners—including raw-material suppliers—perform all of the key supply activities in unison, they can make inventory decisions that lead to dramatically improved results.They can then share the rewards of producing the correct amount of the product, thereby lowering the cost of overproduction. Business-process synchronization also enables partners to respond quickly and easily to unplann ed consumer demand for items or for personalized and enhanced products—the kinds of things today’s Internet shoppers desire. The companies that employ business-process synchronization in the development of their consumerdirect order-fulfillment strategy will fulfill these consumer desires and emerge as the big winners in the Internet economy.Author’s Note Used as a reference for this article was a White Paper by Alan Dabbiere of Manhattan Associates titled â€Å"Business Process and Supply Chain Synchronization: Achieving Supply Chain Excellence Through Technology. † Footnote 1 Companies providing early versions of advanced planning capability include SAP’s Advanced Planning and Optimization (APO) engine, i2Technologies, Manugistics, and Logility. More sophisticated systems that integrate production planning and transportation planning are under development. 70 Supply Chain Management Review Fall 1999

Guanlong Tyrannosaur Facts and Figures

Name: Guanlong (Chinese for crown dragon); pronounced GWON-long Habitat: Woodlands of Asia Historical Period: Late Jurassic (160 million years ago) Size and Weight: About 10 feet long and 100-200 pounds Diet: Meat Distinguishing Characteristics: Small size; large crest on head; possibly feathers About Guanlong One of the earliest tyrannosaurs yet to be discovered, Guanlong (the name, crown dragon, alludes to this meat-eaters prominent crest) roamed eastern Asia during the late Jurassic period. Like other early theropods — such as Eoraptor and Dilong — Guanlong was nothing special in terms of size, only a fraction as large as Tyrannosaurus Rex (which lived about 90 million years later). This points to a common theme in evolution, the development of plus-sized animals from small progenitors. How do paleontologists know that Guanlong was a tyrannosaur? Clearly, this dinosaurs crest — not to mention its fairly long arms and (possibly) its coat of feathers — make it an ill-fitting match with the classic tyrannosaurs of the late Cretaceous period. The giveaway is the characteristic shape of Guanlongs teeth and pelvis, which point to its being a basal (i.e., early) member of the tyrannosaur family. Guanlong itself appears to have descended from earlier, smaller theropods known as coelurosaurs, the most prominent genus of which was Coelurus. Oddly, when Guanlong was discovered, in Chinas Shishugou formation, the paleontologists from George Washington University found two specimens lying on top of one another — one surmised to be about 12 years old, and the other about 7. Whats weird is that, as far as researchers can tell, the dinosaurs didn’t die at the same time, and theres no sign of a struggle — so how did they wind up buried together? Its still a tantalizing paleontological mystery.

The Three Themes of Oedipus Rex - 1106 Words

The Three Themes of Oedipus Rex The contrast between trust in the gods oracles and trust in intelligence and pride plays out in Oedipus Rex. Of course, the irony is, that Oedipuss and the oracles’ methods both lead to the same fallout. Oedipuss hunt for truth reveals just that, and the truth confirms the oracles prophecies. Oedipus kills his father and marries his mother. The irony is that the reader knows this from the very start of this Greek drama. There is also irony in the fact that Oedipus is the one to solve the riddle of the Sphinx, which he embodies in every way, from a crawling baby to an old man with a cane. Oedipus’s life is just a pit of tragedy. Aristotle states, that to arouse emotions such as fear and pity, is to bring about catharsis. This is the aim of a great tragedy. The three themes of the novel Oedipus Rex; Aristotle’s study, the riddle of the Sphinx, and dramatic irony help to enhance the value of knowledge that is bestowed upon the reader, these themes create an awareness and an understanding of what leads to the tragic ending of this meritorious Greek tragedy. Tragedy is compared to metrical forms such as epic and comedy. In Aristotle’s famous study of Greek dramatic art he determines that tragedy, like all poetry, is a imitation, but claims that it has a serious purpose. Tragedies use direct action rather than narrative to achieve its ends (Jones 84). The serious purpose of the novel is to reveal the error in judgement.

Managing the successful design process of HVAC systems Free Essays

Introduction A good HVAC system design plays a critical role in creating an optimal building environment. The design process of a HVAC system is complex process involving client’s needs, building regulation compliance, energy efficiency, environmental impact and sustainability. A lot of different professionals with distinct disciplines, such as clients, architects, structural and service engineers are involved in a building construction project. We will write a custom essay sample on Managing the successful design process of HVAC systems or any similar topic only for you Order Now The design process involves constant communication and clarification between the different team members. By working together at key points in the design process, participants can often identify highly attractive solutions to design needs that would otherwise not be found (1). The effectiveness of the design process in the building industry has a great influence on the success of subsequent processes in the construction of projects and also on the quality of the environment (2). Several studies have also pointed out that a large percentage of defects in building arise through decisions or actions taken in the design stages (3). It is also said that poor design has a very strong impact on the level of efficiency during the production stage (4). In recent years, the increasing complexity of modern buildings in a very competitive market–place has significantly increased the pressure for improving the performance of the design process in terms of time and quality. Despite its impo rtance, relatively little research has been done on the management of the design process, in contrast to the research time and effort which has been devoted to production and project management (5). This essay will concentrate on various issues related to the management of successful design process of HVAC system and put forward arguments to reflect the above. History of HVAC System HVAC is an acronym that stands for Heating, Ventilation and Air Conditioning. HVAC is based on the principle of thermodynamics and heat transfer. The functions of heating, ventilation and air conditioning are interrelated. HVAC systems provide thermal comfort and acceptable indoor air quality. Like many great innovations, earliest heating and plumbing systems originated with the Romans. A hypocaust(6) was an ancient Roman system of central heating / under floor heating; they were used for heating public baths and private houses. English historian Edward Gibbon mentions â€Å"stupendous aqueducts,† when describing the building of public baths in The History of the Decline and Fall of the Roman Empire(7). The Romans built an aqueduct that carried water for many miles in order to provide a crowded urban population with relatively safe, potable water. In modern buildings the design, installation and control systems for these functions are integrated in to HVAC systems. Design Process and Management Throughout the history of mankind, people have always designed things; it is human nature. It may take years to design a new system but it could be made in a matter of hours. When one is trying to design something, drawing is widely used as a most understandable form of communication. Designers sit down and brainstorm a lot of ideas, discard most of them until a suitable one is found for investigation at a more detailed level enabling the best to be chosen (8). In the past the HVAC system was given less priority in term of design on the basis of sub-optimal consideration, such as preferences for certain types of systems, or equipment budget or space constraints imposed by architects (9). Design and construction were carried out by two different parties. Designers used to design the system and walk away. The contractors carried out the HVAC installation and commissioned the systems. Poorly designed HVAC systems pose health hazard and discomfort to the building occupants. The emergence of â€Å"sick building syndrome† led to the realization that the HVAC system itself acts as a breeding and concentration site for pathogens and allergens (9). The duct net work of a central air handling system poses fire hazard as these are ideal path for fire, smoke and explosive gases. They are also prime target for terrorists to release chemical and biological agent into a building. Nowadays, traditional professional practices are replaced by multi-disciplinary practices. A fresher approach is needed to the planning and co-ordination for multi disciplinary buildings and their system designs to facilitate integration and communication across the disciplines (10). It has been pointed out that poor communication, a lack of documentation, missing input information, a lack of co-ordination between disciplines and erratic decision making is the main problem in design management (3). Designers try to achieve satisfactory or appropriate solutions. The design tends to take place through a series of stages during which design components are continually trialled, tested, evaluated and refined. Therefore, most design processes involve much feedback from the different individuals employed to design the system. It can be seen that defects in a finished building also shows the failure to communicate the known technological factors that have been accepted for many years during the design process. The problems caused seem to be due more to the deficiencies in managing communication during the design process, rather than technology failure (3). HVAC systems for the modern buildings must become fully optimized. Comfort, health and safety function required for each area in the facility must be executed perfectly. Performance of a good HVAC system makes economic sense. Optimized HVAC systems reduce the capital cost and equipment space. They provide the best comfort and health which increases productivity (9). Life-cycle cost is greatly reduced because optimized systems operate with the least possible energy. In recent years, the HVAC industry has been under immense pressure to reduce the energy consumed by HVAC plants and increase energy efficiency to conserve fossil fuels and reduce carbon emissions. HVAC systems in typical commercial buildings are responsible for more than 40 percent of the total energy output (11). Low and zero carbon technologies can be integrated into the HVAC systems to achieve sustainability. Properly designed HVAC systems run at peak efficiency maximising energy used without compromising thermal comfort or indoor air quality. It requires an integrated design approach. It has been pointed out that by adopting this type of design, high performance with multiple benefits can be achieved at a total cost lower than all the components used in the project (1). The design process needs to be well planned and controlled, in order to minimise the effects of complexity and uncertainty (12). As the involvement of interdependent professionals’ disciplines with concurr ent design processes is now the norm, well managed design processes with effective communication is the key to minimising errors that could lead to defective buildings or systems in the future (3). A successful HVAC design process involves interactive efforts, Co-ordination and project programming Conclusion HVAC systems play an important role in keeping a building comfortable. The design of HVAC systems involves working with a team of professionals demonstrating various disciplines. Design errors should be prevented or identified during the design process. These design errors are costly in time, rework, money and lost reputations. Effective design of sustainable HVAC system is needed to make buildings survivable in a current climate of very high energy costs. Managing the HVAC design process successfully saves considerable time and money as well as delivering projects on time and within budget. References 1. Building Design.
