Management and Development of Suppliers
monitoring performance to identify poor performing to provide chance to improve to provide a basis for future purchasing decisions maintaining relationship developing capabilities activities by a buyer to improve the capabilities of suppliers to meet the buyer’s short- and long-term goals 4
5
Supplier Measurement Decisions
what to measure quantitative vs. qualitative variables delivery, quality, cost reduction, service levels measurement and reporting frequency reports to both buyer and supplier real-time information in problems, troubleshooting, and expediting daily, monthly or quarterly summary, and annual face-to-face meeting 5
6
Total Purchases + Nonperformance Costs
Types of Measurements categorical system weighted-point system cost-based system Supplier performance index (SPI) version of SPI adjusted for quantity delivered Total Purchases + Nonperformance Costs Total Purchases 6
7
Categorical System Advantages Disadvantages Users Easy to implement
Requires minimal data Different personnel contribute Good for firms with limited resources Low-cost system Least reliable Less frequent generation of evaluations Most subjective Usually manual Smaller firms Firms in the process of developing an evaluation system 7
8
Weighted-Point System
Advantages Disadvantages Users Flexible system Supplier ranking allowed Moderate implementation costs Quantitative and qualitative factors combined into a single system Tends to focus on unit price Requires some computer support Most firms can use this approach 8
9
Cost-Based System Advantages Disadvantages Users Total cost approach
Specific areas of supplier nonperformance identified Objective supplier ranking Greatest potential for long-range improvement Cost accounting system required Most complex Implementation costs are high Computer resources required Larger firms Firms with a large supply base 9

Rationalization and Optimization of the Supply Base
10
11
General Trend: Reduction of Number of Suppliers
Dell more than 140 suppliers in early days and about 40 in 1999 McDonald in US hamburger suppliers: from 170 in early days to 5 in late 80’s potato chips: from 175 in early days to basically 1 in late 80’s reason: best trade off in maximizing value and minimizing risk manage and develop with suppliers that can grow with the company 11
12
Rationalization and Optimization
a continuous process to determine the number and quality of suppliers in the supply base usually a decrease and occasionally an increase in number of suppliers rationalization: how many and which suppliers to keep optimization: analysis the supply base for keeping the most capable suppliers 12
13
Phases and Activities developing systems to evaluate suppliers
evaluating suppliers keeping excellent and significant suppliers replacing mediocre suppliers with better ones initiating supplier development activities to improve performance globally searching for world-class suppliers 13
14
What are the Advantages?
US operations of McDonald hamburger suppliers: from 170 in early days down to 5 in late 80’s potato chips: from 175 in early days to mostly 1 in late 80’s 14
15
Advantages buying from world-class suppliers
closer relationships with fewer, better performing suppliers fewer quality and delivery problems leading-edge technologies opportunities to collaborate use of full-service suppliers remaining suppliers generally larger in size with more capabilities accessing to supplier’s engineering, R&D, design, testing, production, service, and tooling capabilities fuller range of value-adding services outsourcing integrated items reduction of supply base risk qualified suppliers with more consistent quality 15
16
Advantages lower supply base administrative costs
greater information sharing joint problem-solving fewer problem-related interactions with suppliers lower total product cost lower variability in quality and delivery greater production volumes spread among fewer suppliers supplier’s fixed costs spread out over greater volumes incentive for supplier process improvement economies of scale and scope ability to pursue complex supply management strategies supplier development early supplier design involvement just-in-time sourcing development of cost-based pricing agreements 16
17
What are the Disadvantages?
US operations of McDonald hamburger suppliers: from 170 in early days down to 5 in late 80’s potato chips: from 175 in early days to mostly 1 in late 80’s 17
18
Possible Risks supplier dependency absence of competition
putting all eggs in one basket absence of competition less motivation for suppliers to control cost and to improve continuously deterioration in performance because of complacent hard to switch equitable contracts to maintain the relationship supply disruption loss of continuous flow of materials overaggressive supply reduction inadequate supplier capacity if demand increases missing qualified suppliers effort to find new replacement suppliers 18
19
Formal Approaches twenty-eighty rule “improve or else” rule
Pareto principle “improve or else” rule need to improve quickly triage approach categorization of existing suppliers competency staircase approach series of performance milestones 19

Development of Suppliers
20
21
Supplier Development Process Map
1. Identify critical commodities for development 2. Identify critical suppliers for development 3. Form cross-functional team 4. Meet with supplier’s top management team 5. Identify opportunities and probability for development 6. Define key metrics and cost-sharing mechanisms 7. Reach agreement on key projects and joint resource requirements 8. Monitor status of projects and modify strategies as appropriate 21

Product Development by Suppliers of McDonald
Industrial Practice Product Development by Suppliers of McDonald 22
23
New Product Development by Suppliers of McDonald
French fries new way to prepare French fries peel off the skin; immediately dried in the air; slightly fried before frozen storage supplier invested US2.5 million to build a factory on this unproved idea from laboratory 23
24
New Product Development by Suppliers of McDonald
frozen hamburger, from supplier Keystone old days: three times fresh meat to restaurants 1967 supplier tested 9 months for various frozen agents, frozen rate, temperature, ratio of meat and fat, ways to mince meat quick freezing preserve water, leading to finer meat texture by the ice sharing the technology with other McDonald suppliers single customer: McDonald 24
25
New Product Development by Suppliers of McDonald
McNuggets new product idea from McDonald Keystone to get meat from chicken Keystone spent US$13 million to build automated factory for chicken meat processing based on the successful pilot test before the formal approval sharing the technology with Tyson Food 25
26
Questions Why were suppliers of McDonald willing to
develop products for McDonald, often without any guarantee on partnership? share their technology and methodology with other suppliers of McDonald? 26
27
Effect of Operations and Culture on Supply Management
Japanese Influences in Manufacturing Processes 27
28
Japanese Influences in Purchasing
necessary to understand Japanese philosophy and practices in manufacturing from 70’s Japanese ideas being the mainstream manufacturing: material intense with many purchasing and procurement activities 28
29
Philosophy and Practices in Manufacturing (Early 70s to Mid 90s)
affected heavily by Japan Just-in-Time and Lean Manufacturing (Toyota) Keiretsu (Japanese 「經連」) 29
30
Conventional Purchasing versus JIT Purchasing
Infrequent deliveries, possible for a few weeks’ consumption Frequent deliveries for immediate production Inventory on parts Little inventory on parts Delivery time set by buyer Delivery time dictated by production schedule of buyer Multiple suppliers per part, for quality and price Sole to few suppliers per part, Short-term purchasing agreement Long-term purchasing agreement 30
31
Conventional Purchasing versus JIT Purchasing
Free product design Product design to minimize # of parts Traditional information exchange, on quality, quality, price, time, venue More information exchange, traditional plus production schedules, production processes, including real-time information Communication between supplier and purchasing Communication between supplier and multiple sections, e.g., production, design, QC, etc., facilitated by purchasing Supplier set price Buyer work with suppliers to reduce supplier cost and price Proximity of supplier being unimportant Supplier close to buyer 31
