- 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.
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
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.
3 elements of LEAN working in unison
- LEAN manufacturing - Total Quality Management - Respect for People
Lean & Six Sigma complement each other
- Lean focuses on eliminating wastes and improving efficiency - Six Sigma focuses on reducing defects and variations
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
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
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
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
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
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.
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
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
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
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 $
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
VMI from the supplier's perspective
-Avoids ill-advised customer orders -Supplier decides inventory set up and shipments -Opportunity for supplier to educate customers about other products
Collaborative Negotiations
-Both sides work together to maximize the outcome or create a win-win result -Requires open discussions and a free-flow of information between parties
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
Advantages of Decentralization
-Knowledge of local requirements -Local sourcing -Less bureaucracy
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.
Reasons for making
-Protect proprietary technology -No competent supplier -Better quality control -Use existing idle capacity -Control of lead-time, transportation, and warehousing cost -Overall lower cost
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
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.
LEAN Supply Chain Relationships
-Suppliers and customers work to remove waste, reduce cost, and improve quality and customer service -JIT purchasing includes delivering smaller quantities, at right time, delivered to the right location, in the right quantities -Firms develop lean supply chain relationships with key customers. Mutual dependency and benefits occur among these partners.
VMI Co-managed inventories
-Suppliers work from customers' storage areas or at the point of assembly or sale -Bar codes and scanners update computer counts
Advantages of e-procurement system
-Time savings -Cost savings -Accuracy -Real time -Mobility -Trackability -Management -Benefits to the suppliers
Reasons for a single supplier
-To establish a good relationship -Less quality variability -Lower cost -Transportation economies -Proprietary product or process -Volume too small to split -single source very risky, current trends favor fewer sources
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
Public purchasing for government and non-profit sectors is characterized by
-competitive bidding -bidders are generally required to furnish bonds as incentive to ensure that the successful bidder will fulfill the contract awarded
Pull approach
-each stage in the supply chain requests quantities needed from the previous stage -no excess inventory generated -reduced inventory exposes problems
Value Engineering Activities
-help the firm to reduce cost, improve quality and reduce new product development time
respect for ppl
-must exist for an organization to be its best -flatter hierarchy than traditional organization -ordinary workers given great responsibility -supply chain members work together in cross functional teams (roles of workers, management, and suppliers)
role of workers
-workers performing diff tasks and actively pursuing company goals -worker duties - improve production process, monitor quality, correct quality problems -work in teams - quality circles

Developmental: require corrective actions from these suppliers on how they will achieve acceptable level. Look for alternative suppliers if these do not achieve acceptability within a fixed period of time, e.g., 3 months.
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 of overall score. 6. Classify vendors based on their overall score, e.g., Certified, Preferred, Acceptable, Conditional, Developmental, Unacceptable, etc. 7. Audit and perform ongoing certification review.

An approach for designing and redesigning products and services to achieve the same functionality at less cost or achieve better functionality at the same cost;
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.

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.

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?
