About the Project

•  Theprojectwaschallenging,because:– itwasaMajorUpgradeofanexisGngsoHwareproduct

– itrequired“DisconGnuousInnovaGon”andstate-of-the-arttechnologies(weneedtogetontheredcurve)

•  ThereareseveralmodaliGesforrecognizingaproject’senvironment,suchas“Complicated”and“Complex”

•  Inthe“Complicated”environment,CauseandEffectcanbecapturedinplanningphase,evenitseemstobe(almost)impossibleatfirstsight




•  Inthe“Complex”environment,CauseandEffectcannotalwaysbecaptured,evenitappearssoinretrospect

•  ItconstantlychangesaccordingtoexternalcondiGons

• WebelievethatthefollowingpercepGonsaremoreimportantthanusualinthe“Complex”environment– “itisbeZertobeapproximatelyrightthantobepreciselywrong”

– “themorecomplextheproblemis,themoresimplethesoluGonhastobe”

•  Andwebelievethatweshouldbemore“innovaGve”and“invenGve”thanusual




• Weknewthatmoreadaptability,responsivenessandautonomywouldenhancetheintuiGonofdevelopersduringtheproject

• Wedecidedtoapply“Agile”CCPM– Inourpipeline,projectsaremanagedbyeitherstandardCCPM(*)or“Agile”CCPM

*Theterm“standard”CCPMisusedtoavoidconfusionduringthepresentaGon
