  1. Supply Chain Vulnerability, Risk, Robustness & Resilience Helen Peck, Cranfield University In Mangan, Lalwani & Butcher, Global Logistics and Supply Chain Management John Wiley & Sons [2008] Finland 2010

  2. 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

  3. Donald Rumsfeld • What hasn’t happened is interesting • There are known knowns • Things we know we know • There are known unknowns • We know that we don’t know • Y2K • There are unknown unknowns • We don’t know we don’t know • 9/11 • THESE ARE USUALLY THE DIFFICULT MATTERS Finland 2010

  4. Creeping Crises • Systematic supply chain disruptions • Post-9/11 security concerns • Hurricane Katrina • Inadequate managerial controls • Enron (WorldCom; Dutch retailer Royal Ahold; Italian dairy conglomerate ParmalatFinanziara) • Barings Bank • Mitigating legislation • Need Business Continuity Management, due diligence • Sarbanes-Oxley • Basel Accords in International Banking Finland 2010

  5. Supply Chain wicked problems • Level 1: Value stream/product/processes • Flow of work, material, information, money • Level 2: Asset & infrastructure dependencies • Fixed & mobile assets • Level 3: Organizations & inter-organizational network power dependencies • Commercial wellbeing, contractual & stakeholder relationships • Level 4: Social & natural environment • Society, economy & natural environment Finland 2010

  6. Level 1: Process Engineering & Inventory Management • Flows within and between organizations • Underlies lean manufacturing • End-to-end perspective of agile manufacturing • RISK MANAGEMENT • Improved visibility of demand, inventory • Velocity (reduce likelihood of obsolescence) • Tight monitoring and control (TQM, 6 Sigma) • Mastery of process control facilitates identification, management and elimination of risk • But need to consider rest of system Finland 2010

  7. Level 2: Asset & Infrastructure dependencies • Nodes (facilities) & links (roads, trucks, etc.) • Asset-based RISK MANAGEMENT • Catastrophes • IT, supply chain system disruption • Loss of key skills • Probability x severity • Impact on operations of loss of links or nodes through network modeling • Mitigating impacts through business continuity planning Finland 2010

  8. Level 3: Organization & Inter-Organizational Networks • Financial consequences of events or decisions • Loss of sole supplier or customer • Impact on budget or shareholders • Strategic management • Conflicts of interest • RISK MANAGEMENT • Partnering • Dual sourcing • Outsourcing • Contractual obligations • UPSIDE • Look for competitive advantage in core competencies Finland 2010

  9. Level 4: Macro-Environment • Political • Green movement • Wars • Economic • Social • Technological • RISK MANAGEMENT • Risk avoidance • Contingency planning Finland 2010

  11. Supply Chain risk management processP. Chapman, M. Cristopher, U. Juttner, H. Peck, R. Wilding, Logistics and Transportation Focus 4:4 [2002] 59-64 • Risk Identification • Uncertainties: demand, supply, cost {quantitative} • Disruption: disasters, economic crises {qualitative} • Risk Assessment • Political • Product availability • Capacity, demand fluctuation • Technology, labor • Financial instability, management turnover • Risk Avoidance • Insurance • Inventory buffers • Supply chain alliances, e-procurement • Risk Mitigation • Product pricing, other demand control • Product variety • VMI, CPFR Finland 2010

  12. Risk Reduction StrategiesC.S. TangJournal of Logistics: Research and Applications 9:1 [2006] 33-45 • Identify different types of risk • Estimate likelihood of each event • Assess potential loss from major disruption • Identify strategies to reduce risk Finland 2010

  13. Robust StrategiesTang [2006]; Khan & Burnes [2007]; Wagner & Bode [2008]; Manoj & Mentzer [2008] Finland 2010

  14. Risk Context • SUPPLY • Political risk (acts of God, acts of man) • DEMAND • Changes in demand from • Loss of reputation for quality • Loss of technological or design competitive edghe • Unpredictable customer preferences • Economic recession • CONTEXTUAL RISKS • Cultural differences • Environmental risk • Regulations risk • Exchange rate risk Finland 2010

  20. 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

  21. 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

  22. 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

  23. 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

  24. 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

  25. 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
