KeyConceptsStrategy isan“art”,notexactlya science, thismeans focusingon thebigpictureandoverallresultsofaneffort.Herearesomedefinitions:According to the Oxford English Dictionary: “The art of a commander-in-chief; the art ofprojecting and directing the larger military movements and operations of a campaign.”Perspectivesandchallengesofthegeneralandsoldierareverydifferent.According toMerriam-Webster: “Thescienceandartofmilitarycommandexercised tomeettheenemyincombatunderadvantageousconditions.”

SupplychainstrategyTheimportanceofstrategyforsupplychainmanagementhasbeenrecognizedforalongtime.ShapiroandHeskett(1985)highlightedthat“logistics’mostimportantroleisstrategic”.Theyrecommendedthatlogisticsmanagersapplyavarietyofperspectiveswhilerunningtheirlogisticssystems:

• Internalperspective:understandstructure,economicsandrequirementsofthelogisticssystemsaswellasconstraintsandcomponents

• Interfunctionalperspective:interactconstantlywithotherfunctionalmanagersinareassuchasmarketing,production,andfinance

• Channelperspective:thinkintermsofmaximizingthetotalchannelbenefit,consideringthatthefirm’sdecisionsaffectandisaffectedbychannelpartners


33

• Strategicperspective:welldesignedlogisticsmanagementcaninfluencecompany’sstrategyandhasthepotentialto“advanceacompany’sstrategicgoals”

Adichotomy:Thetwofacesoflogistics(supplychainmanagement)Successful supply chainmanagement requires attention to detail, to day-to-day control andcoordination,and to the tacticalandanalytic.However,managers shouldalsobeable to see“thebigpicture,”andbecognizantofthebroad,qualitative,long-termaspectsofsupplychainmanagement.Thisawarenesswillensurethatthefirm’ssupplychainfunction,combinedwiththeotherfunctionalareas,canfurthertheoverallobjectivesoftheorganization.

Porter’sFiveForcesPorter argues that a company’s ability to increase profit is affected not only by rivalry ofimmediate competitors but also by four other forces, which determine the intensity ofcompetitionandtheattractivenessofanindustry.Thesefiveforcesare:

ScenarioPlanningThesecondchallengeisanticipatingfuturesupplychainneeds,whichinashort-termtimelineareidentifiedusingforecastingtechniques.However,foralongertimelineweusethescenarioplanning technique. Scenario planning is a method that shifts from predicting events topreparing for multiple potential futures.

CausesofDisruptionsThesearedifferenttypesofrisksorcausesofdisruptions:

• RandomPhenomena:weatherphenomenaornaturaldisasters• Accidents:anyundesirableevent,suchasexplosions• Governments&Politics:tradebarriers,tradeembargo,militarycoups,political

instability,changesinregulations• Non-Compliance:non-complianceofstandardssuchasairpollution,water

Bow-TieRiskAnalysisFrameworkOne of the classical frameworks for thinking about risk and disruption is the Bow-Tie RiskAnalysisFramework:

DisruptionProfile

Figure:DisruptionProfile


65

ClassificationofRisksThe traditional classification used to prioritize risk, includes two dimensions: probability ofdisruption and consequences. Usually supply chain managers focus on the severeconsequences-high probability quadrant (upper right). However, themost dangerous eventsarethoseinthesevereconsequences-lowprobabilityquadrantbecausecompaniesaretypicallynotpreparedanddonotknowhowtopreparefortheseevents.

In addition to disruption probability and consequences, a three dimensional classificationincludesdetectability.Dependabilityisdefinedashowlongittakesfromthetimeweknowthataneventisgoingtohappenuntilithappens.
