Collaborative Planning Forecasting And Replenishment Commerce Essay

Collaborative Planning Forecasting And Replenishment Commerce Essay Consider a company XYZ which produces various automotive parts. One such part is ABC, for which there is a rise in inventory level. The marketing team decides to launch a promotional campaign to boost the sales and ABC and curtail this rising inventory level. This promotional campaign was a great success and there was an increase in the sales of product ABC. The production department noticed this rise in sales of product ABC and they started producing more of ABC in anticipation of rising demand. This again resulted in an increase in inventory level (negated the entire motive of the campaign). This is a perfect example of the importance of information sharing (collaboration and Communication). A similar kind of issue occurs, when we do not share information in a supply Chain, resulting in Bullwhip Effect. In an organization, if different departments have different owners with different views and goals, they all try to maximize their individual profits. In the path of achieving this, they get deviated from their common goal of maximizing the overall profit of the entire Supply Chain. This deviation from the true goal leads to lack of coordination Inappropriate flow of information Due to incomplete sharing of information between stages (inter-organization and intra-organization), information is distorted. Today, for a given organization, there are a thousand of products. This increase in variety of products makes it next to impossible for the companies to exchange all information among all its suppliers Such inappropriate flow of information results in BULLWHIP effect. Here, fluctuations in orders increase as we move up the supply chain from consumer to retailer to wholesalers to manufacturers. Proctor and Gamble was the first to observe the bullwhip effect in its supply chain for Pampers diapers. They found that the raw material replenishment order at the supplier side had huge fluctuations as compared to fluctuation in demand at retail stores. Same way, HP also found that the fluctuations varied significantly with being very little at resellers point and increasing as moving up in the chain towards integrated circuit division (ICD). Here also, while the variation in product demands were very little, replenishment orders placed with ICD saw much more variability. A similar phenomenon can be seen in apparel and grocery industry. Lack of Coordination and its effects on Performance The Bullwhip effect A supply chain is said to be lacking in coordination if each stage (level) is concerned about optimization of its own objective. In doing so, various individual entities get deviated from a common objective or organizational goal to satisfy consumers by satisfying their needs and there by generating maximum profit for the organization. Information distortion is also one of the causes of Lack of Coordination, as in the case of diaper supply chain of PG. Areas affected by Bullwhip effect Manufacturing cost Inventory cost Replenishment lead time Transportation cost Labor cost Levels of product availability ( service level) Relationship across the supply chain Manufacturing Cost As a result of Bullwhip effect, Manufacturing unit of PG have to produce to satisfy the demand of diapers with much more variability. PG can respond to such variability by either holding of excess inventory or by producing more capacity, both of which leads to increase in manufacturing cost. Inventory cost The Bullwhip effect also results in increase in inventory cost. With increased variability in demand, P%G has to carry a higher level of inventory than would actually require in absence of Bullwhip effect. Thus, we can see a major increase in Inventory cost. A higher level of inventory will also mean an increased warehouse space requirement (again an increase in cost). Replenishment Lead Time The Bullwhip effect results in increased replenishment lead time. With the increase in variability in demand due to Bullwhip effect, scheduling at suppliers and PG are much more difficult as compared to a level demand. There are situations when the available resource (inventory) is not enough to meet the demand and there by resulting in higher replenishment lead time. Transportation cost The Bullwhip effect results in higher transportation cost. With the increased fluctuations in demand due to Bullwhip effect, there is a proportional fluctuation in the requirement of transportation. This results in a rise in transportation cost Labor Cost Labor cost increases in presence of Bullwhip effect. Labor cost at PG and its suppliers increase due to fluctuations in demand. Also, labor cost for receiving at retailers end increases due to this increased uncertainty. Now all these stages have option of either operating at excess labor or variable labor, both of which results in increase in labor cost. Level of Product availability One of the major outcomes of Bullwhip effect is the Out Of Stock situations. As we know, with increase in fluctuations in orders, PG is not capable of satisfying the needs of all its retailers on time, which in turn increases the likelihood of retailers going OOS resulting in a sales loss in the supply chain. Relationship across the supply chain The Bullwhip effect, having a negative effect on performance at all levels of supply chain results in bitterness in the relationship between these various stages of supply chain. Since each stage is working independently and is trying to achieve its individual goal, they are under an impression that they are doing it in right way. They start blaming other department of inefficiency and there by resulting in loss of trust. Performance Measure Bullwhip effect Manufacturing cost Increase Inventory Cost Increase Replenishment Lead Time Increase Transportation Cost Increase Shipping and Receiving Cost Increase Level of Product availability Decrease Profitability DecreaseThus, we can say that the Bullwhip effect has a significant effect on the overall profitability of the supply chain. There is an increase in cost and decrease in responsiveness. Obstacles to achieving coordination in Supply Chain Factors leading to local optimization at various stages of supply chain or increase in information delay are the root cause of difficulty in coordination in supply chain. The five major categories of obstacles are Incentive obstacles Information processing obstacles Operational obstacles Pricing obstacles Behavioral obstacles Incentive obstacle When there is a variation in incentive offered at different stages in a supply chain, there is an increase in variability in the productivity and reduction in total supply chain profits. Local Optimization: Suppose that the incentive of a floor manager at a local grocery store depends up on the profit they generate for that particular store. Here, the managers take all their purchasing and inventory decisions to achieve this goal only and not for the benefit of the entire supply chain. Buying and stocking decisions which are based on single stage optimization can never result in over all supply chain profitability. Improper sales force incentive: Very often, sales force incentive are designed in a manner to achieve local goals. Sales force incentive are based on the quantity sold to the distributors and not the end consumers. For example, consider an umbrella manufacturing firm, which offers its sales force an incentive on the sales target achieved in off season. To maximize their bonuses, sales force convinces distributors to buy more umbrellas even though there is no demand. This results in order variability with more demand in off season and less demand when actually there are sales. This kind of sales forces incentive result in order variability more than customer demand variability. Information processing obstacles Information processing obstacles occurs in a situation when there is a distortion in information regarding demand as it moves from customers to retailers to distributors to manufacturers. Forecasting based on orders and not on customer demand When there is a Bullwhip effect is a supply chain, the only communication between different stages is the orders they receive. Each stage sees its responsibility as fulfilling orders to its downstream. In such a scenario, a very small change in customer demand will result in large variability in orders placed by the distributors. The fact that each stage in a supply chain forecasts demand based on the stream of orders received from the downstream stage results in a magnification of fluctuations in demand as we move up the supply chain from the retailer to the manufacturer. Lack of information sharing Suppose a retailer increases the size of order for a particular product due to its planned promotion. Now, if the manufacturer is not aware of this planned promotion, it will see this increase in order as increase in customer demand and place orders with suppliers accordingly. So, when the retailer finishes its promotion, both manufacturer and distributor has a piled up inventory. Operational obstacles Operational obstacles occur at the time of placing and filling of orders. There are a number of fixed costs associated with placing of order, receiving or transportation of an order. Different retailers may prefer orders in lots to minimize such costs. Thus at the suppliers end there is large variability in order as compared to demand variability at retailers end. Now, if there a number of retailers associated with the same supplier, and due to placement of orders in lots, there might be some days when order may be erratically high as compared to other days as compared to demand. Such situations may also lead to large replenishment lead time. Pricing obstacles Lot size based quantity discounts occurs when there are discounts offered on large lots of order placed. These resulting large lots magnify the Bullwhip effect. There are a number of trade promotions and short term discounts. Such offers always boost orders, which are nowhere in sync up with the real demand. Such forward buying result in large orders during promotional activity or special discount rates but very small orders after that. Behavioral Obstacles Behavioral obstacles are problems in learning within organizations which later on contribute to the Bullwhip effect. Each stage of supply chain acts locally and is not aware of the consequences of its action on others. Different stages of the supply chain react to the current situation locally rather than trying to identify the root cause. Due to lack of common understanding and mutual trust, each stage plays a blame game on each other with no one taking the responsibility of these fluctuations. Lack of trust with in supply chain makes them all opportunistic at the expense of the overall supply chain profitability. This also results in duplication of efforts. Since individual entities do not share ideas and work in isolation, many a times they turn up doing the same task. Means to Overcome obstacles of Collaborative information sharing Collaborative Planning, Forecasting and Replenishment Means to overcome these obstacles Improved information accuracy Alignment of goals and incentive across the channel Building strong partnership and mutual trust Improving Operational Performance All these efforts can be achieved by Collaborative Planning, Forecasting and Replenishment. So what exactly is Collaborate Planning, Forecasting and Replenishment (CPFR)? Here, both sellers and buyers at all the levels come together and collaborate along all or few of these activities. Strategy and Planning Demand and Supply Management Execution Analysis At strategy and planning stage, all the partners involved discuss upon the scope of collaboration and assign roles and responsibilities and define checkpoints. They align all their activities including promotions, new product introduction, store opening and closing and inventory policies. Then, at demand and supply management, sales forecast using point of sales data give an accurate picture of demand. Now, as the forecasts become firm, they are converted to actual orders. Then, processes like production, shipping, receiving and stocking are executed. Now the last but most important task is analysis of KPI. There is always a need for identifying exceptions and evaluating metrics that are used to access performance. One successful CPFR implementation has involved Henkel, a German detergent manufacturer, and Eroski, a Spanish food retailer. Prior to CPFR, Eroski saw frequent stock outs of Henkel products, especially during promotions. At the inception of CPFR in December 1999, 70 percent of the sales forecast had an average error of over 50 percent and only 5 percent of the forecasts had an error below 20 percent. But, just within four months of CPFR implementation, the numbers changed drastically. Forecast errors above 50 percent reduced to 5 percent and more than 70 percent of the time, forecast error was below 20 percent. Customer service level also increased to 90% with an average inventory of just 5 days. CPFR implementation Scenarios Mentioned below are the most common CPFR implementation scenarios CPFR scenario Where applied in Supply Chain Industries where applied Retail event collaboration Highly promoted channels All industry other than those that practice EDLP DC replenishment collaboration Retail DC or distributed DC Drugstores, hardware, grocery Store replenishment collaboration Direct store delivery or DC to store delivery Mass merchants, Club stores Collaborative assortment planning Apparel and seasonal goods Specialty retail Common CPFR Scenarios Retail event Collaboration: In any retail supermarket, there are a number of events such as promotional activities and they affect demand very much.OOS and excess inventory, unplanned logistics cost and order placement costs are sometimes very high and may affect the overall profitability in the supply chain. Here the two parties involved identify specific brands that are to be included in collaboration. Each and every minute detail like promotion time and place, display tactics, advertisement are shared. Once, information sharing is done, a demand forecast is prepared and shared with in the two parties. PG is one such example which has implemented Retail event collaboration with many big retail chains including Wal-Mart. DC replenishment Collaboration This is one of the simplest and mostly used collaboration scenarios, where partners need to collaborate for forecasting on demand and DC withdrawals. This collaboration is comparably easy to implement since this collaboration requires aggregate forecast and does not require sharing of point of sales data. And slowly, with due course of time, this collaboration can be moved up to all other storage points in supply chain (from retail shelves to Inventory warehouse) Store Replenishment collaboration Store replenishment collaboration is one step ahead of DC replenishment collaboration. Here, collaboration is on store level point of sale forecast. These forecasts are used placing store orders. Benefits of store Replenishment collaboration is increased replenishment accuracy, improved service level and less Out of Stock situations, reduced inventory and greater visibility of point of sales data. Collaborative Assortment Planning For fashion apparels and seasonal products, demand follows a seasonal pattern. Thus, collaborative planning in these categories follows seasonality Hence, the forecasts rely more on collaborative understanding of industry trends, customer tastes and less on horizontal data. Why is CPFR important? Consider a consumer walking in to a retail grocery outlet to find that the product which he is looking for is not available (out of stock). For the consumer, it is great inconvenience and for the store owner, it is a loss of revenue. Such a situation is not only a plague in retail industry, but also a nightmare for manufacturing sector. Out Of Stock of one particular inventory in the manufacturing line can lead to zero overall production (bottlenecks). Mostly (70% to 75%), out of Stock occur at retailer level. Reasons for Out of Stock at retailer level: Lengthy Ordering Processes/Cycles Underestimated demand Un stocked shelves even though the products are at the store So, what is required to tackle such problems? End to end information channel Point of Sale information coming from retailer to the supplier. CPFR is one such process where we use common tools to capture data at all stages in the supply Chain. Pioneers to this practice are Wal-Mart and Tesco. They first linked their Point of Sale data from Retail stores to their Warehouses. This laid down the bricks to the building of an open information infrastructure. The second and more critical task in implementation of CPFR is managing cultural change. There has to be a willingness to share information. A mutual trust between different stakeholders is a must, since the required information to be shared is confidential most of the time. Benefits of Collaborative Planning, Forecasting and Replenishment Lower inventory levels Increased sales Less overhead Reduced human errors ( data exchange) Better insight in customer demand resulting in better resource utilization, reduced inventory requirements. Improved and direct communication with customers Opportunity to provide category management Reduced replenishment time Less redundancy Increase service level and reduced stock outs Lower Inventory Level By having knowledge of exact inventory status of customer, the supplier has better control on lead time of his inventory. He knows his exact inventory requirements due to lower uncertainty. A better forecasting leads to lowering the need for safety stocks (also termed as buffer stock is the level of extra stock maintained to mitigate the risks of stock outs due to uncertainties in forecasting). All these factors combine to result in lower inventory. Increased Sales CPFR in place ensures the product availability at any given point. This results in a better customer experience and customer satisfaction. A satisfied customer becomes your loyal customers. A loyal, regular customer generates more revenue than a first time customer. Also, less stock outs at outlets result in less customers returning without any purchase. This results in increased sales. Better Resource Utilization Proper knowledge of customer demand due to end to end information sharing, results in a better forecasting. An improved forecasting numbers result in more planned decisions, clarity of mind in terms of inventory requirements and so a better RU plan. Increased Service Level Collaborative Planning, forecasting and Replenishment builds up a better forecasting model. In CPFR system, at each level, a supplier has access to real time sales and inventory data of a customer. As soon as the inventory goes below the safety level, a replenish order call is triggered. It helps customers to operate at higher service levels and lower inventories. Now, these are the benefits every supplier aspires for. Challenges in implementation of CPFR It is a universal truth that no benefit comes without a cost. Same way, with so many benefits associated with Collaborative Planning, Forecasting and Replenishment, there are also few risks and hurdles to its implementation. With sharing of information at such a large scale, its misuse is one such risk. Often, one entity may have relationship with various competitors. Another risk involved is viability of change in technology. If one of the partners in collaboration changes its technology, the other is forced to do so or it may lose its collaboration. Thirdly, with the requirement of close interaction of the partners, a variation in their cultures can also play a very important role in making decisions of CPFR implementation. The inability to foster a collaborative culture across the partner organizations can be a major hurdle to the success of CPFR. However, one of the biggest challenges is that the demand information which is shared between the partners is often not used in an inte grated manner within the organizations. It is imperative to have integrated supply and demand, logistics and corporate planning within the organizations. This will help in maximizing the overall profit generated in the supply chain. Factors affecting Distribution Network design Elements of customer service influenced by network structure: Response time Product variety Product availability Customer experience Order visibility Return ability Supply chain costs affected by network structure: Inventories Transportation Facilities and handling Information Supply Chain Costs affected With a better visibility due to information sharing, the inventory requirement decreases, thereby reducing overall inventory cost. Also, a common supplier may have information (real time) of all its customers and can very easily club in various orders. This can be achieved by using MILK RUN model of distribution One truckload stopping at multiple points to replenish various customers. This helps him to reduce his transportation cost also. Implementation of centralized information systems (ERP, SAP) may eliminate the hassles of manually data entry and transfer. Though, the onetime cost of implementation of such systems might be very high, they reduce the human error probability. Such errors may result in inaccuracy in forecasting which will again result in higher inventory costs and out of stocks (loss of sales). Elements of Customer Services influenced Response time and Product availability CPFR builds up a better forecasting model. The actual demand information is used to generate replenishment orders. This helps vendors to improve their response time and less out of stock situations in the retail outlets. Customer Experience When a customer walks in to a retail store, there is a lesser chance of him finding an out of stock situation. Product availability (right product at right place) helps to increase customer satisfaction. Order Visibility With CPFR in place, the supplier can see the customer demand in actual and can anticipate the orders. This helps in reduction in errors in forecasting. A well informed and collaborated partners increases order visibility. All this is possible only due to Collaborative information sharing in the system.

Aids, Poverty and Ignorance in South Africa :: South Africa AIDS Disease Health Essays

Aids, Poverty and Ignorance in South Africa Twenty years after the first clinical evidence of Acquired Immunodeficiency Syndrome (AIDS) was reported, it has become the most devastating disease humankind has ever faced. Since the epidemic began, more than 60 million people have been infected with the virus worldwide. Data shows an estimated 57,520,805 infected people around the world with that number increasing by approximately 1,400 people per day (redribbon.co.za). AIDS is now the leading cause of death in sub-Saharan Africa. Worldwide, it is the fourth-biggest killer. At the end of 2003, an estimated 46 million people globally were living with AIDS. In many parts of the developing world, the majority of new infections occur in young adults, with young women especially vulnerable. About one-third of those currently living with AIDS are aged 15–24. Most of them do not know they carry the virus. Millions more know nothing or too little about AIDS to protect themselves against it. Dr. Malegaparu Makgoba, Presiden t of the Medical Research Council of South Africa, warns that â€Å"as Africa faces the challenges of its renewal or renaissance, there is no greater potential barrier to the attainment of this vision than the specter of the HIV/AIDS epidemic† (mrc.ac.za). The most affected part of the world has been Sub-Saharan Africa, in particular South Africa. The groundbreaking article released at the end of 2002 by the Medical Research Council of South Africa, the â€Å"Impact of HIV/Aids on adult mortality in South Africa† report is the first comprehensive examination of mortality statistics from the AIDS era. In a strongly worded introduction to the report, Dr. Makgoba states that as a consequence of early beliefs that AIDS was a disease exclusively due to homosexuality and that â€Å"many Africans promoted the notion that homosexual practices were ‘unAfrican’, thus sowing the seeds for denial to justify why AIDS would not be prevalent in their communities† (mrc.ac.za). He believes that â€Å"this denial was compounded by stigmatization, chauvinism, the distortion of scientific evidence, and ignorance† (mrc.ac.za). The report shows data proving that AIDS is the biggest killer in South Africa—with an estimated 40% of adult deaths during 2003 were caused by AIDS. According to the researchers of the ‘Impact of HIV/AIDS on Adult Mortality in South Africa’, AIDS will continue to be a growing problem in South Africa.

Protein Thermal Stability Essay -- Scientific Research, Amino Acids

Proteins are organic polymers made up of chains of amino acids and are crucial material in many biological functions (Reece and others 2011). There are twenty basic amino acids, eight of which are essential to the adult human diet and must be consumed rather than synthesized inside the body. These essential amino acids are isoleucine, leucine, tryptophan, lysine, valine, phenylalanine, methionine, and threonine, with an added requirement of histidine in the diet of children (Potter and Hotchkiss 1995). Nonessential amino acids can be synthesized from these, and all amino acids are used as monomers to construct proteins which perform numerous important functions in the body (Reece and others 2011). Most amino acids exist as isomers and are given a designation based on whether they rotate a plane of polarized light to the right or to the left, known as dextrorotatory â€Å"D† or levorotatory â€Å"L† isomers, respectively (Al-Holy and Rasco 2007). It should be noted that only L amino acids are used in protein synthesis (Weber and Miller 1981). The biological functions of proteins include increasing the rate of biochemical reactions in the form of enzymes, moving important substances to where they are needed in the form of transport proteins, regulating the body in the form of hormones, allowing the body to move in the form of contractile proteins, and providing support in the form of structural proteins (Reece and others 2011). In addition, proteins have a great deal of functionality in foods, including providing essential amino acids as well as energy, viscosity, texture, water holding capacity, foaming and emulsification properties, and allowing gel formation (Culbertson 2007). As mentioned above, essential amino acids provided by th... ... p. Reece JB, Urry LA, Cain ML, Wasserman SA, Minorsky PV, Jackson RB. 2011. Campbell biology. 9th ed.

Human Services Essay

The book, â€Å"Men are from Mars, Women are from Venus† by John Gray, generally, explores the claim that men and women are different and it is this difference that makes relationships fail and/or succeed. Using an allegorical backdrop, he presented his hypothesis by narrating how men originally was from Mars, where, they value success, titles and positions and how women originally was from Venus, where they value relationships, communication and empathy. At a particular point, lives on both planets became meaningless until a Martian glimpsed a Venetian and the Venetians felt loved and cherished, thus, they fitted the gap missing in their lives and opted to live on earth. This story was carefully enhanced as each personality is explored, taking into account their background, their reactions, feelings, expectations as well as coping mechanisms. I can see how positive Gray is, in pursuing his claim, presenting the facts, examples as well as possibilities of the situation. I can also say that most of his concepts are true – that women are indeed very â€Å"emotional† and that men are very â€Å"logical†. On the other hand, this will only be applicable for couples who are willing to make a relationship work. I do not think this will work effectively in a relationship where, let’s say, the man does not understand how a woman think or where a man does not know that women are like â€Å"tides†. I think in the end, women are still going to give – that they will still be â€Å"trapped† in such situation where they have no choice but to give and obliged to understand men. In a way, I don’t like the idea that men fill in the void the women feel when they encounter their down moments. I don’t like the idea that a Venetian is in need of a Martian. Perhaps, I’m just in a rebellious state that I feel that way but I never liked the idea that a woman can’t live without a man in her life. I believe that women are able and are very capable to sustain a living. Such that if a woman is being beaten by her husband, or if a woman is being abused, or if a man validates his vices as a coping mechanism when he is in his cave, the woman has every right to fight back or even leave her husband. She shouldn’t disregard her needs as a woman just because she is waiting for her husband to come out of his cave or have his rubber band pulled back. She shouldn’t let anybody step over her boundaries just because she is naturally, understanding. In the field of human services, the information about men and women will greatly help in dealing with people. It’s hard to separately discuss how acting out, catharsis and repression is related to concepts mentioned in the book so I will be citing possible examples instead. In cases of teenage drug abuse, it is important to trace how it started, or particularly, why it did. Getting these people to talk, be it a man or a woman is never easy. For one, their current coping mechanism may be a result of continuous nurturing of repressed emotions. While time is a big element in these types of situation, using Gray’s concepts teach us to allow them space until they are ready to discuss their issues. Force rarely works in these scenarios, nor is immediate rehabilitation. For youngsters, parents’ participation in this process is very crucial as children may have repressed emotions that need attention. Parents should be educated on â€Å"how to listen† while children will have to be â€Å"advised† on how to â€Å"accept† or â€Å"communicate. † For adults, one’s behavior or treatment greatly matters. Gray’s notes on how to motivate a man or a woman, or encourage them to talk will help in these types of scenarios. In child abuse or rape cases, they say it’s far easier to assign a woman to interview the victims. This is true, because women in general, know how to empathize with the victims as well as understand the situation. Men, normally, try to put on their â€Å"Mr. Fix It Personality† to help a victim feel better – which rarely works and usually pushes the victims into their own comfort zones – choosing not to talk, instead. Gray’s notes on how to make people talk starts from the very basic – being silent and being ready at any time to accommodate the victim. In dealing with the elderly or senior citizens, it will be very different. The provider has to understand that not only does gender matter here but also the psychosocial stage a person is in. Dealing with senior citizens do not constitute a relational aspect, some may even feel insulted if you try to look at it in that perspective. Gray’s ideas in considering the person’s culture (or background) and understanding the person’s individuality (gender and personality) will help in making such relationship fruitful and successful. Health services may seem very specific and require lesser attention or relational aspect. This is true. In a manner of speaking, health provided is based on the results of a test or exam conducted/surveyed on a specific community. On the other hand, some people may refuse to accept help or decline it outright; thinking that they don’t need it or their pride has been insulted. Thus, it is important for health providers to be relational, helping people understand the benefits of the help being provided so that it can be accepted more freely. Imagine, how you can convince a tribe or group to accept vaccine if they had been practicing herbal medicine all throughout their lives? Or how you can convince a community to take advantage of vaccines when their families have opted not to take them for the longest period of time? Although, I believe this is very rare, Gray’s concepts will help a person get acquainted with his/her patients by merely taking into account how men and women vary in reacting to various factors. Knowing that Gray focused on how to make relationships work, it becomes easier to apply his concepts to something general, such as human services – where people deal with other people. Gray’s concepts may even be applied or associated to a group, for Martians did belong to one culture and Venetians belong to another, and very likely, together they share or may have built a different culture too. With this in mind, relating to others will become an everyday adventure, rather than a routinary assumption and prediction of behaviors. It will constitute facts and bases on how personalities can be so similar, yet so different.
