Definitions • Risk: • Decision theory – range of possible outcomes & their values, upside gains & downside losses • Hazard or threat (technological risk; political risk) • Safety & Engineering: Downside consequences of rational decision (worst case scenario) • Supply Chain Vulnerability: • What has disrupted operations in the past? • What known weaknesses do we have? • What ‘near misses’ have we experienced? • What would be the effect of a key material shortage? • What would be the effect of the loss of a distribution site? • What would be the effect of the loss of a key supplier or customer? • Robust Strategy: • Firm able to manage regular demand fluctions regardless of disruption • Resilience • Ability of the system to return to its original (or desired) state after disturbance Finland 2010

Rolls Royce Early Supplier InvolvementG.A. Zsidisin, M.E. Smith, The Journal of Supply Chain Management [Fall 2005] 44-56 • Aerospace Division • Industry driven by cost, reliability • Extensive R&D • Rolls Royce typically 3-4 years for new product • Industry averaged 10 to 20 years • Supplier-provided components 65-80% Finland 2010
Rolls Royce ESI process • Establish customer need • Identify EDI project • Develop component target costs • Prepare ESI project & milestones • Inform business units • Determine commodity breakdown • Develop potential supplier list • Develop business objective • Supplier workshops • Review expectations with suppliers • Conduct ESI workshop • Value engineering, evaluate prices & technical • Evaluate & score suppliers • Make recommendations • Inform suppliers • Develop working agreements & implement Finland 2010
ESI Benefits • Reduced threat of excessive costs • Reduced legal liabilities • Improved quality • Relaxed supplier capacity constraints • Reduced product development time • Better able to handle product design changes • Better control over supplier leadership issues Finland 2010
Risk of DisintermediationJ.F. Mills & V. Camek, International Journal of Physical distribution & Logistics Management 34:9 [2004] 714-727 • Motokov UK Ltd • British importer/distributer in tractors, tires • TRACTORS • Landini – Italian agricultural machinery manufacturer • Initially marketed through Edwards Ltd tractor dealership • Replaced with exclusive dealership (Motokov) for 3.5 years • Replaced with newly formed Landini UK distribution • Landini had damage settlement expenses when terminated with disintermediated firms • Felt they obtained better control, worth expense Finland 2010
Tires • Motokov dealt with Matador Tyres • Exclusive UK distributors • Tires frangible, low margin • Matador disintermediatedMotokov in early 1990s • 1994 Motokov rebuilt business around Barum tires (Czech) • Barum acquired by Continental, who reconfigured their supply chain • 1995 Motokov dropped Barum, returned to Matador • No longer sole importer • 2002 Matador acquired large customers wanting reduced costs • Source producer dealt directly with customers • Motokov too small, disintermediated Finland 2010
Tractors • Zetor a Czech tractor producer, founded 1946 • 1960s supplied UK through Motokov • Late 1990s Zetor had financial problems • Full capacity, but no profit • 1998 to 2000 halted production • Before 1998 Motokov sold about 600 Zetor tractors per year • 2000 down to 200 • Zetor would benefit from buying out Motkov, reduce costs Finland 2010
