12. The Evolution of Cooperation – Tit for Tat • Achieving win-win outcomes requires changing incentives from defection to cooperation • How might this be achieved? Nice Retaliating Forgiving Non-envious

13. Does This Build Trust? • Suppliers develop design proposals, OEMs send their plans around to get competitive quotes • OEMs demand immediate 5% price cuts • OEMs abruptly change policy and make suppliers responsible for tooling cost • OEMs run reverse auctions in which aggressive bids pushing prices lower can’t be verified later as coming from legitimate suppliers • Supplier quality problems on major components/ subsystems are perceived by public (and in legal liability cases) as OEM responsibility

15. Suppliers’ View • "The Big Three [U.S. automakers] set annual cost-reduction targets [for the parts they purchase]. To realise those targets, they'll do anything. [They've unleashed] a reign of terror, and it gets worse every year. You can't trust anyone [in those companies]." • Director, interior systems supplier to Ford, CM, and Chrysler, October 1999 • "Honda is a demanding customer, but it is loyal to us. [American] automakers have us work on drawings, ask other suppliers to bid on them, and give the job to the lowest bidder. Honda never does that." • CEO, industrial fasteners supplier to Ford, CM, Chrysler, and Honda, April 2002 • "In my opinion, [Ford] seems to send its people to 'hate school' so that they learn how to hate suppliers. The company is extremely confrontational. After dealing with Ford, Idecided not to buy its cars." • Senior executive, supplier to Ford, October 2002 • "Toyota helped us dramatically improve our production system. We started by making one component, and as we improved, [Toyota] rewarded us orders for more components. Toyota is our best customer." • Senior executive, supplier to Ford, CM, Chrysler, and Toyota, July 2001

19. The Supplier Working Relations Index

22. Discussion Given the success of the Japanese model, should one always aim for: .. long-term supplier relationships? .. collaborative relationships? .. single-sourcing?

23. Power in the Supply Chain • Everyone in the supply chain seeks to appropriate value for themselves from participation! • Certain players recognise that they have limited power to appropriate value, but would seek to leverage more value if they could • Understanding power structures is important for explaining inter-organisational dynamics • Toyota model: • Transforming power through creation of hierarchies of structural dominance. Toyota is dominant player, able to control key resources that appropriate value • Creates dependents (suppliers) who provide no threat to the flow of value appropriation Source: Cox 1999

26. The Role of Incentives • Problem - Incentives offered to different stages or participants in a supply chain lead to actions that increase variability and reduce total supply chain profits = Misalignment of total supply chain objectives and individual objectives (excess inventory, stock-outs, incorrect forecasts, higher manufacturing costs, loss of supply chain innovation) • Causes – • Hidden actions • Hidden information • Badly designed incentives • Local optimization within functions or within stages of a supply chain

27. Aligning Goals and Incentives • How to go about it? (Narayanan & Raman, HBR 2004) • Acknowledge that an incentive misalignment exists • Diagnose the cause for the misalignment • Change incentives (rewrite contracts, reveal hidden information, develop trust) to reward partners for acting in the supply chain’s best interests • Review periodically, and educate managers across tiers • Align incentives so that each participant has an incentive to do the things that will maximize total supply chain profits

28. Secrets of Effective Relationships • Long-term collaboration • Commitment to shared future • A fair profit • Understand the supplier • “Collaboration is not about a photoshoot of people with their arms around one another. My definition is about the right quality, right time, right supplier, right plan, and right total cost. And if I am not hitting on all of those cylinders, it may be because I am not providing the right information on what we need, or we have great clarity, but they are not interpreting it properly. We need to understand what is going on with their world, their signals, and flows and interpretations of what we are asking them to do.” • Frank Crespo, Chief Procurement Officer at Caterpillar

29. Secrets of Effective Relationships • Tough, but helpful (Toyota, Honda) • Parallel sourcing to create positive pressure • Send monthly report cards to core suppliers, feedback • Supplier development to build capabilities • Share information intensively, but selectively • Improvement is realised in collaboration, not isolation • Continuous improvement (Kaizen) • Exchange best practice, Sharing of gains • Supplier study groups (Dyer, 1996)

30. Secrets of Effective Relationships • Trust, but verify • Strong supervision of suppliers (scorecards, supplier performance management) • Supplier evaluation • ”We gave away a lot of elements of [design] work that we’d always done in the past, and then didn’t provide the kind of oversight necessary for some of the people that were doing work that they’d never done before” • Jim Albaugh, Boeing Dreamliner (2007)

31. 3T’s of Effective Supply Chains

32. Takeaways • Effective supply chain management requires seeking global optimum – which may mean sub-optimising at a local level • Collaboration is a challenge – often the most difficult element of managing supply chains • Two key drivers of relationship dynamics: • Power • Incentives • Effective relationships have some combination of reward and punishment (ie, tough but helpful)
