Define and calculate forecast error & know what forecast bias is
•Forecast Accuracy: measure of how closely forecast aligns with demand •Bias: tendency to over or under predict future demand (forecast error)
Define/explain the Law of agency
•Gives legal status to supply personnel •Gives the authority as an agent of the organization to attend to the business of supply in accordance with the instructions given by his or her employer -Typically instructions are a job description
Direct benifits
•Largest potential source of cost savings -Leverage effect -ROA •The bottom line
List the reasons for having a single supplier and the reasons for having multiple suppliers and explain the benefits that preferred suppliers provide customers
Single-sourcing is utilized when multiple suppliers cannot provide the input (e.g., if the input is under patent protection) or sourcing the input from multiple suppliers could create major coordination challenges. Multi-sourcing arrangements are utilized for many items by most large organizations. Using multiple sources helps to spur competition between vendors, protect the firm against risk by having multiple sources of supply, and avoid becoming overly dependent on a single supplier.
Commercial Arbitration

Explain the relationship of forecast accuracy to time horizon and level of detail
As the forecast horizon shortens, forecast accuracy increases. For instance, a forecast for tomorrow will be more accurate than a forecast for next month; a forecast for next month will be more accurate than a forecast for next year; and a forecast for next year will be more accurate than a forecast for ten years in the future.

Define Collaborative Planning, Forecasting and Replenishment (CPFR) and explain its benefits and process
Collaborative, planning, forecasting and replenishment (CPFR): supply chain partners share forecast, and demand and resource plans to reduce risk -Market Planning: changes to products, locations, pricing and promotions -Demand and resource planning: forecasting -Execution: order fulfillment -Analysis: data on key performance metrics
Discuss the primary goals of purchasing and explain how purchasing can contribute to these goals.
Ensure uninterrupted flows of raw materials at the lowest total cost, improve quality of the finished goods produced, and maximize customer satisfaction. Actively seeking better materials and reliable suppliers, work closely with and exploiting the expertise of strategic suppliers to improve quality and materials, and involving suppliers and purchasing personnel in new product design and development efforts.
indirect benefits
Good forecasting/strategic order sizes ease burden of inventory management Fewer cycle counts, holding costs, and lost/expired inventory Higher quality can lead to less re-work, returns, scrapped products Minimize potential operational/reputational risk
Define a sourcing strategy, how should this align with the corporate strategy?
Sourcing does not strictly mean only looking to purchase cheap products but the emphasis is on acquiring newly formed business partnerships. While many companies only look to benefit from cheaper manufacturing, others look for specialized skills or the creation of leaner operations. Furthering efficiency and ultimately achieving business objectives are common goals of sourcing.

List and define the procurement process, explain what the steps are and why this process is a. needed despite its cost and complexity
Stage 1: Identify Goods or Services Needed The onset of the procurement process begins when a business has a need for goods or services. These goods or services can be internal - meaning any materials required to run the business, or external - materials that the business will eventually sell. This stage also includes setting a budget. Take, for example, a company that supplies tires for automobiles. One of their local branches is running low on a particular type of tire. In this stage, they would determine the type of tire, how many tires they need, when they need them to arrive, and approximately how much they should cost. Stage 2: Explore and Select Vendor(s) This stage is all about sourcing potential vendors and determining their ability to provide the best value and quality for your goods or services. While the stage seems straightforward, it's important to find vendors who not only deliver a high quality product for a competitive price, but who have a strong reputation. Ideally, you would build a mutually beneficial relationship that can last long-term, if necessary. Best practice in this area is known as strategic sourcing. This would be a less responsive approach to procurement as the preferred supplier for most key purchase requirements will already be in place. Using our tire supplier company as an example, during this stage, they would develop a short list of all the different tire manufacturers and wholesalers that provide the type of tire they need. The selection criteria would weigh cost, quantity, reputation, speed of service, dependability, and customer service - then select the best fit. Sub-processes in this stage could include tendering, bid management, compliance checks, contract management, supplier relationship management, etc. Stage 3: Submit Purchase Requisition The next stage in the procurement process involves getting the thumbs up from the internal department that controls finances to purchase your goods or services. This includes creating a purchase requisition document and submitting it to that department. It's important to note here that you're not actually ordering anything from the vendor, you're getting the internal approval to do so. The process of turning a purchase requisition into a purchase order is known as the purchase order process. Depending on your company's procurement process this could be straightforward or could include multiple steps of approval depending on the value of the order. While purchase requisitions vary depending on the organization, the tire supplier would share the following information with purchasing for their approval: purchaser's location or department (name of branch), the quantity and description of supplies requested (30 winter tires, size 215), the name of the vendor that is providing the goods (e.g. Firestone®), and the price ($1,500). The tire supplier would then share this document directly with the purchasing department for approval, rejection, or further discussion. Stage 4: Create Purchase Order This is the part of the procurement where the buying happens. Once the purchase requisition has been approved, the department that controls finances issues a purchase order (PO) to the vendor. Purchase orders are typically created using electronic purchasing systems or a full Procure-to-Pay software like PurchaseControl, which enable businesses to track POs and submit them electronically. If there are no contracts involved, purchase orders are considered legally binding documents. Again, information may vary, but our tire supplier's purchase order would include the name of the company purchasing the goods or services (ABC Tire Company), the description and quantity of the goods or services (30 winter tires, size 215), price ($1,500), a mailing address (15 Fake Lane, Sacramento, CA, 12345), payment information and terms (to be paid in 45 days), invoice address (same as mailing address), and a purchase order number (345). Stage 5: Receive Invoice and Order This stage in the procurement process - receiving the invoice and the order - may or may not happen together; one may arrive before the other. The vendor sends an invoice to the purchaser which describes exactly what the order includes. The invoice confirms the sale and reaffirms exactly when the payment is due. When the purchaser receives the order, they typically have a limited amount of time to notify the vendor of any issues with the good or service. At this point, three documents - purchase orders, order receipts (which arrives with the order), and vendor invoices - are aligned and reconciled, highlighting any discrepancies to ensure that what you are being charged matches what you have received. Stage 6: Pay for Goods or Services The next step in the procurement process will involve the company's finance team. Upon receiving the order and invoice as described, the accounts payable team will process the invoice. Matching the invoice against an approved PO and the delivery details for the order follows a best practice called three-way matching in the accounts payable process. If everything matches up the accounts team sends payment to the vendor within the specified timeframe. Stage 7: Record for Audit The final stage in the procurement cycle is important for all around good bookkeeping and for audit purposes. Auditors require thorough documentation of all purchases, so all relevant documents from purchase requisition through invoice should be stored in one central location.

Explain the importance of strategic sourcing as a tool to help companies achieve strategic goals and a. how your sourcing strategy must support the objectives of your product
Strategic sourcing is an approach to supply chain management that formalizes the way information is gathered and used so an organization can use its consolidated purchasing power to find the best possible values in the marketplace and align its purchasing strategy to business goals. your sourcing strategy must support the objectives of your product. In order to effectively implement strategic sourcing in your organization, it is necessary to analyze the suppliers, their profiles, and their core capabilities. Once this is accomplished, an organization is equipped with information that will allow them to match their business objectives to their ideal suppliers.
Explain the importance of metrics like TCO and continuous improvement for improving supplier relationships
TCO: made up of all costs associated w/acquisition, use, & maintenance of a good or service. •The process of evaluating suppliers based on a set of mutually agreed-upon performance measures provides opportunities for continuous improvement making a series of small improvements over time results in the elimination of waste in a system. •Buyers and suppliers must be willing to continuously improve their capabilities in meeting customer requirements of cost, quality, delivery, and technology.
Use the weighted average scorecard to evaluate supplier performance and apply the results
The Weighted-Criteria Evaluation System 1.Select the key dimensions of performance mutually acceptable to both customer and supplier. 2.Monitor and collect performance data. 3.Assign weights to each of the dimensions. 4.Evaluate performance measures between 0 and 100. 5.Multiply dimension rating by weight and sum overall score. 6.Classify vendors based on their overall score: Unacceptable, Conditional, Certified, & Preferred Audit and perform ongoing certification review.
Discuss the Make/Buy decision and list the reasons why a company chooses to outsource an item a. and the reasons it chooses to make an item
The decision as to whether to make vs. buy a product is based on a variety of factors, including the cost of either option, whether the product is available from other vendors, the expertise and resources your business has when it comes to manufacturing, and whether you have enough cash in place to make a purchase.
Return-on-Assets Effect
The effect of purchasing on the Return-on-Assets (ROA) percentage - stemming from cost reductions to inventory asset base and represented on the balance sheet
Profit Leverage Effect
The profit-leverage effect of supply savings is measured by the increase in profit obtained by a decrease in purchase spend
What is the profit-leverage effect of supply? In what specific ways could you improve profit through supply management?
The profit-leverage effect of supply savings is measured by the increase in profit obtained by a decrease in purchase spend. While this leverage is more effective than boosting sales, its different for organizations who have spent years on their supply system. Increasing savings through supply will become increasingly difficult.
Explain in your own words how to apply TCO techniques for evaluating supplier quotes
Total cost of ownership (TCO) is a financial estimate that helps consumers and enterprise managers determine direct and indirect costs of a product or system. TCO goes beyond the initial purchase price or implementation cost to consider the full cost of an asset over its useful life. A TCO analysis often shows there can be a large difference between the price of something and its long term cost.

How might social or political issues impact a supplier selection decision?
government legislation requiring suppliers on government contracts to place a percentage of business with designated service disabled-, veteran-, minority-, or women-owned business has forced many purchases to undertake such searches for suppliers companies in the private sector tend to do this voluntarily out of a sense of corporate social responsibility and to gain strategic advantage Political - "buy local" is a common requirement for city and state purchasing officials "buy american"
