Gantt chart

John Jones, senior VP for Zanda Corp., is looking at three alternative aggregate production plans for the next six-month period. At his company, demand varies by month with substantial month-to-month differences. The three alternatives are a "pure level plan," which keeps an absolutely constant workforce, a "pure chase plan" relying on hiring and layoffs, and a hybrid plan. He is most likely to find that the hybrid plan: Has higher hiring/layoff cost than the chase plan and higher inventory carrying cost than the level plan. Has lower inventory carrying cost than the chase plan and higher hiring/layoff cost than the level plan. None of these. Has lower inventory carrying cost than the level plan and lower hiring/layoff cost than the chase plan.

Has lower inventory carrying cost than the level plan and lower hiring/layoff cost than the chase plan. Since hybrid plans combine aspects of level and chase, they typically have less inventory than level, but more than chase. They also typically have more hiring/layoff than level, but less than chase.

Which of the following statements most accurately represents the challenge of being environmentally sustainable?

It is not easy to be environmentally responsible since the choices facing management involve trade-offs.

Which of the following statements most accurately represents the challenge of being environmentally sustainable? Being environmentally responsible is simply a matter of complying with governmental regulations. The choices facing the firm are clear, and the obvious candidates for improvement can be easily identified. It is not easy to be environmentally responsible since the choices facing management involve trade-offs. This is a decision that firms must move on since the demand for environmental responsibility is driven by forces that cannot be ignored—governmental regulations, decreasing resource levels, and changing customer demands.

It is not easy to be environmentally responsible since the choices facing management involve trade-offs. As illustrated in the discussion presented in the section, it is not easy to be environmentally responsible since there are significant and conflicting trade-offs that must be addressed—trade-offs where there is no obvious "right" answer.

Which of the following statements concerning the Malcolm Baldrige award is true? The Baldrige system represents a comprehensive framework, comprising of seven categories, for quality management and performance measurement. The award was established by the U.S. Congress in 1987 to promote better quality management practices and improved quality results by worldwide competitors. The Baldrige criteria are based upon 1,000 points, allocated among four categories: strategic planning, information systems, business results, and conformance to documented procedures, policies, and training. A disadvantage of the Baldrige award process is its lack of flexibility, requiring each participating firm to utilize the same standardized approach. A disadvantage of the Baldrige award process is its lack of a framework for internal assessment of quality and performance improvement systems.

The Baldrige system represents a comprehensive framework, comprising of seven categories, for quality management and performance measurement. pp. 170-172, the Baldrige system represents a comprehensive framework, comprising of seven categories (see Table 8.3), for quality management and performance measurement

Supplier Evaluation: Weighted Criteria

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 dimension based on importance (total = 100%). 4) Evaluate performance measures between 0 and 100. 5) Score = Dimension rating x weight. Overall score = Sum of individual scores. 6) Classify vendors based on their overall score, -->Certified, Preferred, Acceptable, Conditional, Developmental, Unacceptable, etc. 7) Follow up and take action based on the classification 8) Audit and perform ongoing review (- Categorize suppliers based on performance scores - Meet regularly with each supplier to review performance report (monthly, quarterly, annually) )

Planning bills can be best described as: A) grouping like items together for planning. B) products which the factory plans to build. C) indented bill of materials. D) phantom bill of materials.

The correct answer is: A A planning bill is an artificial grouping of components for planning purposes. They are used to simplify planning, forecasting, master production scheduling, and material requirements planning. They do not represent products which are buildable.

In order for a forecast to signal negative bias, the tracking signal would be: A) less than one. B) more than one. C) equal to one. D) equal to zero.

The correct answer is: A A tracking signal measures the algebraic deviations of the actual demand to the forecast. It then divides those deviations by the MAD. If the deviations divided by the MAD are greater than one, then the forecast exhibits positive bias; less than one, the forecast exhibits negative bias. Most companies will only adjust the forecast when the tracking signal reaches an arbitrary target, such as +/- 4.

Which of the following best describes the term bias? A) Actual demand consistently varies from forecast; either above or below. B) The standard deviation is consistently positive. C) The mean absolute deviation equals the forecast error. D) The sum of the errors is less than the MAD.

The correct answer is: A Bias occurs when actual demand varies consistently higher or lower than the forecast. When bias occurs in the forecast, the forecast must be adjusted.

A firm planned order is used to: A) freeze the planned order against changes in quantity and time. B) convert the planned order to a scheduled receipt. C) simulate the projected inventory balance. D) manipulate the data and quantity of the customer order.

The correct answer is: A Firm planned orders are used by planners when it is necessary to "freeze" the planned order. This might be necessary due to material shortages or capacity problems, e.g., strikes.

The attributes of the product or service that cause a customer to buy from a company are called the: A) order winners. B) order qualifiers. C) buyers criteria. D) order modifiers.

The correct answer is: A Order winners are the characteristics that cause a customer to purchase from a supplier. These characteristics can vary widely but will generally include delivery speed, delivery reliability, quality, design superiority, education of the employees, customer importance, service, etc.

The term, Value Chain, refers to the: A) total value generated by a company's activities. B) total revenue for all the products and services. C) supplier network for providing goods and services. D) margin associated with the activities.

The correct answer is: A The Value Chain refers to the total value generated by a company. It is comprised of value activities and margin. Value activities can be broken into two types; primary and support. Primary activities are those concerned with the physical creation of the product or service which a company sells. Support activities are those which help brace the primary activities such as technology, human resources, accounting, etc.

Which of the following are steps in developing a Master Production Schedule? I. Develop a preliminary MPS II. Check the schedule against the capacity available III. Check MPS against the production plan to ensure they are equal A) I and II B) I and III C) II and III D) I, II, and III

The correct answer is: A The three steps in developing a Master Production Schedule are: 1. Develop a preliminary MPS. 2. Check the preliminary MPS against available capacity. 3. Resolve differences between the preliminary MPS and capacity available.

A tracking signal is used to: A) monitor the quality of the forecast. B) determine the variation in the production plan. C) measure whether the schedule is being met. D) measure the material plan.

The correct answer is: A Tracking signals are used to measure the quality of the forecast to determine whether to adjust the forecast. They usually measure the sum of the errors against a deviation measure such as MAD.

A bill of materials contains: I. Components used to make a product II. Labor needed to build the product III. Assemblies at various stages of production IV. Safety stock by item A) I and II B) I and III C) II and III D) III and IV

The correct answer is: B A bill of materials contains all of the components used in the manufacture of end items. In addition, the subassemblies at various stages of manufacture are described. Labor is defined in the routing, generally in standard hours, and safety stock is not generally maintained on the bill of materials.

Demand on a work center is caused by the next work center. Product is not made unless signaled by the next work center. This is called: A) push system. B) pull system. C) demand system. D) MRPII system.

The correct answer is: B A pull system starts with demand from a customer and signals each preceding operation. Work is not done on a product unless a signal for demand is generated, thus "pulling" a product through the manufacturing process.

All of the following are principles of forecasting except: A) Forecasts are usually wrong B) Forecasts are more accurate for end items C) Forecasts should include an estimate of error D) Forecasts are more accurate in the near term

The correct answer is: B Forecasts are more accurate for product families or groups. The reason is that aggregate numbers tend to be more accurate than detailed numbers. So although the sales forecast error may be very small in a company, predicting the shipments of an end item will have more error associated with it.

In which of the following manufacturing environments are forward scheduling and finite loading best suited for providing customer promise dates? A) Make-to-stock B) Make-to-order C) Assemble-to-order D) Configure-to-order

The correct answer is: B Forward scheduling assumes that materials are not ordered and operations are not scheduled until the customer order is received, regardless of the due date. In a make-to-order environment, work does not begin until the order is received from the customer. The order is then scheduled forward from the order date and considers the load on the finite capacity of each work center through which the order must move.

You are working as a Master Scheduler in a discrete manufacturing company. A large customer has asked if you can deliver an order, but you have some short term capacity constraints. Which of the following actions could be taken so the order can be delivered? I. People could be hired II. Overtime could be worked III. Inventory could be built in slow times IV. Work could be subcontracted A) I, II, and III B) II, III, and IV C) I, III, and IV D) I, II, and IV

The correct answer is: B Short term capacity can be increased by overtime, inventory, or subcontracting. Often, hiring qualified people takes much longer than the other three options.

Which of the following are strategies to use in developing a production plan? I. Chase strategy II. Delphi strategy III. Level strategy IV. Backlog strategy A) I and II B) I and III C) II and IV D) III and IV

The correct answer is: B The chase strategy means production will vary with demand (inventory stays level). The level strategy establishes production at the average demand. Fluctuations in demand are absorbed by inventory. The third strategy is subcontracting. Production is kept at the minimum demand level. Variations in the demand level are absorbed by subcontracting production.

Based on the following data, what should the monthly production be to level production? Beginning inventory = 500 units Ending inventory = 200 units Sales forecast Month 1 2 3 4 5 Quantity 400 300 400 400 300 A) 250 B) 300 C) 350 D) 400

The correct answer is: B The company has a beginning inventory of 500 units and will be decreasing the inventory by 300 units over the 5 periods.

The primary purpose for forecasting is: A) estimating safety stock. B) determining resource and capacity requirements. C) projecting product demand. D) level loading the master schedule.

The correct answer is: C The primary purpose of forecasting is to project product demand. Based on those projections, safety stock can be estimated, resource and capacity constraints can be identified, and the master schedule load strategy can be determined. However, these occur only after projecting what the product demand will be.

The forecast for a part is 200 units per week. The actual shipments for the last 5 weeks have been 250, 260, 210, 240, and 220. If the MAD is 20, what would the tracking signal equal? A) 3 B) 6 C) 9 D) 12

The correct answer is: C Tracking signals measure the bias in a forecast. The above demand would reflect a negative bias in the forecast, as the forecast is consistently less than the actual demand. To calculate a tracking signal, divide the sum of the forecast errors by the MAD. Therefore: 50+60+10+40+20 = 180 180/20 = 9

Design for Six Sigma (DFSS)

An extension of six sigma tools and concepts used for developing new products. The rationale for DFSS is that it is much easier to design quality into a product than it is to fix problems after the design is complete. Instead of using the lean sigma DMAIC framework, DFSS uses IDOV (Identify, Design, Optimize, and Validate) or DMADV (Define, Measure, Analyze, Design, and Verify). DMADV is defined as: • Define the project goals and customer (internal and external) deliverables. • Measure and determine customer needs and specifications. • Analyze the process options to meet the customer needs. • Design the process to meet the customer needs. • Verify the design performance and ability to meet customer needs.

Keys to Successful Strategic Partnerships

1) Build Trust- With trust, partners are more willing to work together, find compromise solutions to problems, work toward achieving long-term benefits for both parties, and go the extra mile. 2) Shared Vision & Objectives- Both partners must share the same vision and have objectives that are not only clear but mutually agreeable. -The focus must move beyond tactical issues and toward a more strategic path to corporate success. 3) Personal Relationships- Strategic Partnerships begin with the development of personal relationships between key people at each company -One to one relationship at all levels of the organization -It is people who communicate and make things happen 4) Mutual Benefits & Needs-Partnership should result in a win-win situation, which can only be achieved if both companies have compatible needs. -An alliance is a relationship, if only one party is happy, then the relationship (i.e., alliance) is not likely to last 5) Commitment & Top Management Support- Commitment must start at the highest management level. -Partnerships tend to be successful when top executives are actively supporting the partnership 6) Change Management- Companies must be prepared to manage change that comes with the formation of new partnerships -Companies must be able to move forward and change together to be successful 7) Information Sharing & Lines of Communication- Both formal and informal lines of communication are maintained to facilitate free flow of information. -Confidentiality of sensitive information must be maintained and is part of the Trust factor 8) Aligned Capabilities- Key suppliers must have the right technology and capabilities to meet cost, quality, and delivery requirements in a timely manner (current and future) -The capabilities must be synergistic for maximum benefit 9) Performance Metrics-You can't improve what you can't (or don't) measure -Measurements related to the firm's strategic objectives should be used to evaluate key suppliers -Measures related to quality, cost, delivery, and flexibility are commonly used in supplier evaluations. -Metrics should be: 1) understandable, 2) easy to measure, and 3) focused on real value-added results [S.M.A.R.T. objectives] -->S.M.A.R.T. = Specific, Measurable, Achievable, Relevant, Time-oriented

Trends in Supplier Relationship

1) Close alignment of sourcing with supplier relationship management - Many companies are determining their negotiation strategies by tying them to their category management strategy, and to their supplier relationship goals. 2) Focus on cross-functional engagement - A best practice for strategic supplier relationships involves SRM teams at both the company and at the supplier, each led by a relationship manager, who form a steering committee to lead the process. 3) Focus on innovation - Companies that engage in more innovation with suppliers, report higher ROI. 4) Investment in people & "soft skills" - Treat suppliers with the courtesy and respect. Be candid, and able to disagree without being disagreeable. Hold both sides to the same standards.

traditional approach to supply chain management?

'volume is king' - buy huge quantities to get lowest price possible

hybrid purchasing organization :Decentralized - Centralized

(large multiunit org) decentralized purchasing at the corporate level and centralized purchasing at business unit level.

Reasons for buying or outsourcing

*Cost Advantage -Especially for components that are non-vital to the organization's operations. Suppliers may have economies of scale *Insufficient Capacity -A firm may be at or near capacity and subcontracting from a supplier may make better sense. Extended Workbench *Lack of Expertise Firm may not have the necessary technology and expertise *Quality Suppliers may have better technology, process, skilled labor

Pressures for Low Inventories

*inventory costs* 1. interest and opportunity costs 2. storage and handling costs 3. taxes, insurance, and shrinkage costs - theft, obsolescence, deterioration

ISO 140000

- A family of standards for environmental management. - The benefits include reduced energy consumption, environmental liability, waste and pollution, and improved community goodwill.

Third-Party Logistics (3PL)

- A growing industry that involves managing a firm's sourcing or materials and/or product distribution responsibilities - 3PL providers charge a fee for services. Typically generates an estimated savings of 10 to 20% of total logistics costs - Benefits include improved service, quality, and profits for their clients. - Vendor-managed inventory (VMI) services - One of the more popular roles of 3PL. - Lead logistics provider (LLP), aka 4PL - A primary 3PL provider; one that oversees other 3PL's

Supplier Evaluation and Certification

- A process to identify best and most reliable suppliers - Sourcing decisions are made on facts and not on perception - Frequent feedback can help avoid surprises and maintain good relationships - Suppliers should be allowed to provide constructive feedback to the customer

Information sharing and lines of communication

- Both formal and informal lines of communication should be set up to facilitate free flow of information. - Confidentiality of sensitive information must be maintained

Benefit of Supplier Certification

- Building long-term relationships - Reducing time spent on incoming inspections - Decreasing the supplier base - Recognizing excellence

Outsourcing allows a firm to

- Concentrate on core capabilities - Reduce staffing levels - Accelerate reengineering efforts - Reduce management problems - Improve manufacturing flexibility.

Ethical Policies should include

- Determining where all purchased goods originated and the manner in which they were made - Knowledge of the suppliers' workplace principles - Inclusion of ethics as a performance rating - Independent verification of vendor compliance - Report of supplier compliance to stakeholders - Provision of detailed ethical sourcing expectations to suppliers

ISO 9000

- Developed by International Organization for Standardization (ISO) - series of management and quality standards in design, development, production, installation, and service. - Companies wanting to sell in the global market seek ISO 9000 certification.

Inventory and Setup Time Reduction

- Excess inventory is a waste - Reducing inventory levels can create production problems - Once problems are detected, they can be solved. - The end result is a smoother running organization with less inventory investment.

3 elements of LEAN working in unison

- LEAN manufacturing - Total Quality Management - Respect for People

Supplier development programs are designed to achieve

- Lower supply chain total cost - Increased profitability for all supply chain participants - Increased product quality - Improved reliability at each point in the supply chain

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

Benchmarking

- Measuring what other businesses do best and matching their performance, is an effective approach to improving your supply chain. - Benchmarking data regarding sourcing practices can be obtained in any number of ways, both formal and informal.

Value Added Process

- Process step that transforms or shapes a product or service which is eventually sold to a customer

Non-Value Added Process

- Process steps that take time, resources, or space, but do not add value to the product or service

Preferred Suppliers Provide

- Product and process technology, and expertise. - Product development and value analysis. - Information on latest trends in materials, processes, or designs. - Capacity for meeting unexpected demand. - Cost efficiency due to economies of scale

Criteria Commonly Used in Certification Programs

- Product quality rates (defective product). - Non-product issues (e.g., on time delivery). - No significant negative incidents - Recognized agency certified or successfully passing a recent audit - Fully documented process & quality system with cost controls & continuous improvement capabilities - Supplier's process is stable with proper controls - Supplier's financial health

SRM is often a part of the rollout of Strategic Sourcing and is typically applied with suppliers:

- Providing high volumes of a product/service - Providing lesser quantities of a crucial product/service - That serve many business units of a company or organization - Where intensive engineering, manufacturing and/or logistics interaction is essential

In the 90's, supply chain management combined

- Quick response (QR) - speed and flexibility - Efficient Consumer Response (ECR) - speed and flexibility - Just-in-Time (JIT) - Continuous reduction of waste - Keiretsu Relationships - Including suppliers in JIT/TQM efforts

Performance Metrics

- Related to quality, cost, delivery, and flexibility used to evaluate suppliers

Supplier Relationship Management

- SRM is the discipline of strategically planning for, and managing, all interactions with the third party organizations that supply goods and/or services to an organization in order to maximize the value of those interactions. - Most supply professionals view SRM as an organized approach to defining what they need and want from a supplier and establishing and managing the company-to-company link to obtain those needs. - about IDENTIFYING AND MEASURING SUPPLIERS

Keys to Successful Partnerships

- Shared vision and objectives - Mutual benefits and needs - Commitment and top management support - change management - Information sharing and lines of communication - Capabilities - Continuous improvement - Performance metrics

SRM seeks to improve profits and reduce costs using tools such as:

- Sourcing Analytics - Sourcing Execution - Procurement Execution - Payment and Settlement - Supplier Score-carding - Performance Monitoring

Resources for learning about implementing sourcing practices:

- The Center for Advanced Purchasing Studies. - Council of Supply Chain Management Professionals (CSCMP) - Institute of Supply Management (ISM)

ISO certified suppliers are preferred by procurement departments

- They have to conform to an externally defined and industry developed set of standards for quality and service. - They have formal processes in place for continual improvement of their products, services, and processes - Certification is done by an external agency not subject to bias or influence - Firms have to be re-certified every three years - They are easier and quicker for procurement to qualify

Lean is

- a culture - NOT a tool box of methods, ideas, or methodologies - provides value for customers through the use of most efficient resources possible - a standard in many industries - Results in: large cost reductions, improved quality, increase customer service

Profit-Leverage Effect

-A decrease in purchasing expenditures directly increases profits before taxes (assuming no decrease in quality or purchasing total cost). -Bottom line impact is $ for $

Supplier Evaluation

-A process to identify best and most reliable suppliers -Sourcing decisions are made on facts and not on perception -Frequent feedback can help avoid surprises and maintain good relationships. -Best Practices enable suppliers to provide constructive feedback to the customer to improve the overall relationship

Purchasing contributes to its objectives by:

-Actively seeking better materials and reliable suppliers -Work with the expertise of strategic suppliers to improve quality and materials -Involving suppliers and purchasing personnel in new product design and development efforts.

Electronic data interchange (EDI)

-Allows a supplier to profile demand and determine accurate forecasts -EDI also provides reorder point data to permit timely deliveries

Request for Quotation (RFQ)/

-Buyer issues a Request for Quotation (RFQ) for routine / repeat purchased items

Advantages of Centralization

-Concentrated volume -Leveraging purchase volume - Avoiding duplication -Specialization - Lower transportation costs - No competition within units -Common supply base

Processing costs for small value purchases are minimized through

-Credit Card/Corporate Purchasing Card (P-card) -Blanket or Open-End Purchase Orders -Blank Check Purchase Orders -Petty Cash -Stockless Buying or System Contracting -Standardization & Simplification of Materials & Components -Accumulating Small Orders to Create a Large Order -Using a Fixed Order Interval

NOT a characteristic of goods

-Extensive customer contact

Inventory Turnover Effect

-Increased inventory turnovers indicate optimal utilization of space and inventory levels, increased sales, avoidance of inventory obsolesce. -Inventory is an asset but it is $ tied up

Successful Strategic Partnerships

-Involves both parties work together, sharing information and the risks and rewards of the relationship -Long term relationship as opposed to a tactical position focused on short term gains.

Supplier Evaluation: Performance

-It is important to actively monitor a supplier's performance and provide visibility and feedback on supplier performance at each stage of the evaluation process. -Some relevant metrics include: -->Price and cost performance -->Product quality -->Delivery performance -->Financial stability -->Compliance to contractual requirements and standards -->Participation in process improvement and product development efforts -->Support of company ethics and sustainable practices

Reasons for multiple suppliers

-Need more capacity -Spread risk of supply disruption -Create competition -More sources of information -Dealing with special kinds of business

Supply Base Rationalization (also called s.b. reduction/ s.b. optimization

-Often initial supply chain management effort - Reduce supply base to the lowest number of suppliers possible without increasing risk

Supplier selection is based on

-Product and process technologies -Willingness to share technologies & information -Quality -Service -Cost -Reliability -Order system & cycle time -Capacity -Communication capability -Location

Preferred Suppliers provide

-Product and process technology, and expertise. -Product development and value analysis. -Information on latest trends in materials, processes, or designs. -Capacity for meeting unexpected demand. -Cost efficiency due to economies of scale.

Buyer-Supplier partnerships are easier with a rationalized supply base and result in

-Reduced purchase prices - Fewer supplier management problems - Closer and more frequent interaction between buyer and supplier - Greater levels of quality and delivery reliability

A forecast analyst has just extracted the recent actual sales history and, in reviewing the data, notices several outliers. The analyst should most likely: A) rerun the data to ensure there were no errors in the extract. B) rerun the data but remove the outliers. C) ignore the outliers and use the forecasts as is. D) refer to the tracking signal.

The correct answer is: B Outliers are data that are outside the general data points of the actual data. These outliers occur due to the random events of business. Sometimes they are caused by the actions of the business such as promotions, bonus timing, etc. Generally speaking, outliers should be removed from the data as they are apt to skew the forecast causing demand projection which are less than accurate. There are times when the outliers are left in the data because it results in very little inaccuracy.

Which of the following statements is most correct? A) The MPS shows families of products. B) The MPS has more detail than the production plan. C) The production plan has more detail than the MPS. D) The production plan rolls up to equal the MPS.

The correct answer is: B The MPS is a weekly build plan that contains more detail than the production plan. However, the MPS should add up to equal the production plan.

The annual demand for a product is 1200 but during July, the product sells 150 units. What is the seasonal index for the product in July? A) 1.0 B) 1.5 C) 1.75 D) 2.00

The correct answer is: B The seasonal index is calculated by dividing the period average demand by the average demand for all periods. For this problem: The seasonal index equals 150 units/100 units or 1.5; where 100 units is the average demand for all periods (1200 units/12 months).

Over the past three months, the demand for a product has been 240, 260, and 280. Calculate the three month moving average forecast for month four. A) 240 B) 260 C) 280 D) 300

The correct answer is: B The three month moving average is calculated by adding the demand for the three months (240+260+280 = 780) and dividing by the number of data (3). Therefore: 780/3 = 260. This would be used as the forecast for the fourth month.

Which of the following is the primary benefit of a customer partnership? A) Higher prices can be charged because the customer is not buying from other sources B) Reduced paperwork between the two parties C) Lower costs in the supply chain for both companies because of the mutual sharing of information D) Higher margins for the supplier

The correct answer is: C A customer partnership (similar to a supplier partnership) will have an overall effect of lowering costs in the supply chain for both partners. These savings can be shared by the companies. The costs are lowered because the partners share information collaboratively. Information on new designs, forecasts, customer orders, consigned inventory, shared contracts, etc. all contribute to the lower costs.

The following formula represents which forecasting technique? New forecast = (alpha)(latest demand) + (1-alpha)(previous forecast) A) Weighted moving average B) Double exponential smoothing C) Exponential smoothing D) Focus forecasting

The correct answer is: C Exponential smoothing uses a smoothing constant called alpha. It smoothes the variation between latest actual demand and the forecasted demand.

In make to stock requirements, customer orders are satisfied from: A) available capacity. B) work in process inventory. C) finished goods inventory. D) raw material inventory.

Based on the following data, what should the monthly production be to achieve level production? Beginning inventory = 300 units Ending inventory. = 400 units Sales forecast Month 1 2 3 4 5 Quantity 300 400 200 300 200 A) 200 B) 250 C) 300 D) 350

The correct answer is: C The company is beginning with 300 units and wants to increase the inventory level by 100 units. In addition, the sales forecast calls for 1400 units to be sold over the 5 periods. Therefore, 1400 + 100 units need to be produced for a total of 1500 units over 5 periods, or 300 units per period.

What is the Mean Absolute Deviation for the following data? Period 1 2 3 4 5 Forecast 100 100 150 150 150 Demand 90 105 140 160 170 A) 3 B) 9 C) 11 D) 15

The correct answer is: C The mean absolute deviation is calculated by adding the absolute value of the difference between the actual demand and the forecast, divided by the number of periods. For this example, the absolute deviation is calculated by adding 10+5+10+10+20=55. Divide 55 by the number of periods (5) to equal 11.

Based on the following data, what would the projected forecast for month 5 be, using a 3 month moving average? Month 1 2 3 4 Forecast 200 200 200 200 Actual Demand 190 210 190 170 A) 170 B) 180 C) 190 D) 200

The correct answer is: C The three month moving average is found by taking the actual demand for the last three months divided by three. Therefore, the calculation would be: (210+190+170)/3 = 570 570/3 = 190

SCM seeks to incorporate LEAN elements using

- Cross-training - Satisfying internal customer demand - Quickly moving products in the production system - Communicating demand forecasts and production schedules up the supply chain - Optimizing inventory levels across the supply chain - Channel integration - extending alliances to suppliers' suppliers and customers' customers

Waste Reduction

- Firms reduce costs and add value by eliminating waste from the productive system. - Waste encompasses wait times, inventories, material and people movement, processing steps, variability, any other non-value-adding activity. - Before Waste is removed, processes are often scattered, which can negatively affect your customers - After Waste is removed, processes are more streamlined, resulting in more satisfied customers. You'll also save your organization time and money

Early Supplier Involvement (ESI)

- Highly effective supply chain integrative techniques - Key suppliers become more involved in the internal operations of the firm, particularly with respect to new product and process design, concurrent engineering and design for manufacturability techniques

The typical approach to supplier development is based on the following process steps:

- Identify critical products and services - Identify critical suppliers - Form a cross-functional team internally to work with the supplier - Meet with the top management at the supplier to get their support and involvement - Identify key development needs and projects - Define details of the agreement and the action plan - Monitor the status of the projects / action plan and modify strategies as necessary

Strong Supplier Partnerships

- Important to achieving win-win competitive performance for the buyer and supplier - These require a strategic perspective as opposed to a tactical position - Involves "a mutual commitment over an extended time to work together to the mutual benefit of both parties, sharing relevant information and the risks and rewards of the relationship"

Purchasing function is one of the most value-enhancing functions in any organization

- It is preferable to periodically monitor the purchasing function's performance against set standards, goals, and/or industry benchmarks. - Surveys or audits can be administered as self-assessments among purchasing staff as part of the annual evaluation process.

Lean & Six Sigma complement each other

- Lean focuses on eliminating wastes and improving efficiency - Six Sigma focuses on reducing defects and variations

Criteria used in Certification Programs

- No incoming product lot rejections (e.g., less than 0.5 percent defective) for a specified time period. - No incoming non-product rejections (e.g., late delivery) for a specified time period - No significant supplier production-related negative incidents for a specified time period - ISO 9000/Q9000 certified or successfully passing a recent, on-site quality system evaluation - Mutually agreed-upon set of clearly specified quality performance measures - Fully documented process and quality system with cost controls and continuous improvement capabilities - Supplier's processes stable and in control

Mutual benefits and needs

- Partnership should result in a win-win situation, which can only be achieved if both companies have compatible needs. - An alliance is much like a marriage, and if only one party is happy, then the marriage is not likely to last

Risks associated with outsourcing, include

- Potential loss of control - Over production decisions, and intellectual property - Increased reliance on suppliers - Increased need for supplier management

Trends in Supplier Relationship Management

- Sourcing and procurement are increasing in importance in organizations. They are becoming more strategic - More companies expect more cost reductions to come from their procurement functions - Staff is being reallocated from low-level transaction activities to more strategic and higher value-added positions - Companies with effective transaction activities tend to reduce costs better and have strategic and automated systems

History of Lean

- Starting 1910's, Henry Ford's mass production line was a first breakthrough by using continuous assembly and flow systems that made parts find their way into finished products - In the 1940's, Taichii Ohno and Shigeo Shingo created the Toyota Production System (TPS), which incorporated Ford's production system and other techniques to form the basis of what is now known as LEAN. - The term LEAN was first coined by John Krafcik in 1988 and the definition was expanded in the 1990 book, The Machine that Changed the World.

Two-Bin System

- quantity equal to order point quantity is put into bin 2 - when bin 1 is used up, use bin 2 while bin 1 is refilled

ISO certified suppliers are frequently preferred by procurement departments

- They have to conform to an externally defined set of standards for quality and delivery of service - They are usually more open to sharing supply chain information - They welcome building relationships with their customers - They have formal processes in place for continual improvement of their products, services, and processes - They are easier for procurement to initially qualify and periodically audit - Certification is done by an external register agency - Firms have to be re-certified every three years

advantages of producing to order? (3)

- abiity to provide product which meets exact needs -reduced costs of holding inventory -higher prices

2 disadvantages of JIT control?

- costs of raw materials likely to be higher -problems may be met in getting raw materials on time

When evaluating suppliers to be used in a collaborative relationship

- purchase cost becomes relatively less important, particularly with key suppliers - the assumption is that excellent suppliers will be able to drive costs out

Value is...

- the inherent worth of a product as judged by the customer and reflected in its selling price and market demand - defined as anything for which the customer is willing to pay

Bid bonds/surety bonds

- to ensure that the successful bidder will accept the contract once awarded

Independent Demand Inventory pertains to

- wholesale and retail merchandise - service industry inventory - end-item and replacement-part inventories - MRO - maintenance, repair, and operating supplies

desired customer service level metrics

-% of orders shipped on schedule -% of line items shipped on schedule -% of dollar volume shipped on schedule -idle time due to material and component shortages

Benefits of implementing an effective supplier certification program include all of the following:

-Building long-term relationships -Reducing time spent on incoming inspections -Recognizing excellence

Drivers of Strategic Sourcing

-Reduce costs and reduce delivery cycle times -Improve quality and long-term financial performance -Optimize the number of global suppliers -Increase customer focus -Reduce high costs of materials -Deliver more innovative products, more frequently, and less expensively than competitors

Small Batch Scheduling

-Small batch scheduling drives down costs by: -Reducing purchased, WIP, and finished goods inventories -Makes the firm more flexible to meet customer demand -Small production batches are accomplished with the use of kanbans -Kanbans generate demand for parts at all stages of production creating a "pull" system

VMI from the buyer-firm's perspective

-Supplier tracks inventories -Determines delivery schedules and order quantities -Buyer can take ownership at the stocking location -Buyer may also be able to avoid taking ownership until the material is actually being used.

advantages of outsourcing? (4)

-can react to changes more quickly -providers may be more specialised and so more efficient -lets a firm focus on its core business -no disruption to normal production

4 types of mass customisation?

-collaborative- work with customers to produce product which suits their needs -adaptive- customised product which can be changed -transparent-unique products offered but not marketed as customised products -cosmetic- marketed in different ways

visual signals

-communication between workstations -Kanban - signal or card in japanese -contains info passed between stations -authorizes production or the movement of materials to the next workstation

how to improve response and dependability? (3)

-effective and up to date tech -flexbile workforce -close relationships with suppliers

A company with a number of physically separate plants has a centralized tool room. This tool room in the past has been responsible for emergency repairs. Whenever equipment (e.g., a spindle, boring machine, transfer line) in one of these separate plants breaks down, the affected items are brought to the tool room, where they are repaired. In some cases, the breakdowns affect production schedules. In other cases, the breakdowns are more annoying but do not adversely affect schedules. Complicating the operations in the tool room is the fact that many of the plans for the equipment are incomplete or out-of-date, thus resulting in "make from sample" requests (the broken part is provided and the tool room is asked to make the replacement piece just like the broken part). It is difficult to predict what equipment will break down and when. Furthermore, the company owns a wide variety of equipment. What are the order winners and order qualifiers in this scenario?
