  • 8. © 2009 IBM CorporationApply Principles of Lean AgileOverall goal: Achieve quality, speed and customer alignment8Eliminate wasteBuild Quality InCreate KnowledgeDefer CommitmentDeliver FastRespect PeopleOptimize the whole
  • 9. © 2009 IBM CorporationEliminate WasteCommon Causes of Waste:–Manual handoffs between teams–Wait times for environments–Delays in test acceptance–Tests against “wrong” environments9
  • 10. © 2009 IBM CorporationEliminating Waste10Result: 15-35% reduction inaverage deliverycycle timeInfrastructure and EnvironmentDeliverablesApplication-Under-Test Deliverable• Automate smoothand error-free hand-overs of ready-use-deliverables• Integrate testing withexisting buildprocesses
  • 11. © 2009 IBM CorporationBuild Quality InCommon Barriers:–Mismatched environments between Dev, Test & Prod.–No single source of truth–Long times needed to reproduce, isolate and fix defects–Ops has low confidence in deliverables received11
  • 12. © 2009 IBM CorporationBuilding Quality In12Result: 30 - 40% reductionin outages• Automate deploymentand functional testingof dev changes onproduction-likeenvironments• Manage applicationand infrastructurechanges together
  • 13. © 2009 IBM CorporationCreate KnowledgeCommon Barriers–Too much “tribal knowledge”–Lack of meaningful metrics–Lack of feedback loops–Inconsistent toolsets13
  • 14. © 2009 IBM CorporationCreating Knowledge14• Leverage andshare standardizeddefinitions ofenvironmentpatterns• Provide reliablevisibility andtraceability toisolate andrecreate defectsResult: Reproduce andcommunicate defects85% faster
  • 15. © 2009 IBM CorporationDefer CommitmentCommon Barriers–Inflexible architectures–Lack of integrated tools–Poor visibility across teams–Poor understanding ofapplication health15
  • 16. © 2009 IBM CorporationDeferring Commitment16• Integrate monitoringof applications forearly identification ofperformance issues• Raise visibilityinto deliveryquality and testedconfigurationsResult: Up to 35%improvement indevelopmentefficiency
  • 17. © 2009 IBM CorporationDeliver FastCommon barriers–Different processes fordifferent teams–Rollbacks in production– Integration delays–Too many requests forenvironments17
  • 18. © 2009 IBM CorporationDelivering Fast18Result: Deliver environments3 times faster Deliver 4 times morereleases per year• Provide 1-clickdeployment ofenvironments fortesting• Apply infrastructureas code: deliverapplication andenvironmentchanges together
  • 19. © 2009 IBM CorporationRespect PeopleCommon barriers–Disconnected teams–Lack “one source of truth”–Lack of understandingacross teams–“Finger-pointing”19
  • 20. © 2009 IBM CorporationRespect People20Result: 98% improvement inmeeting service levelagreements (SLA)• Incorporate self-service deploymentsof personal testsandboxes into IDE• Provide commonrepositories & views allteams can leverage(single source of truth)
  • 21. © 2009 IBM CorporationOptimize the WholeCommon barriers–Cultural challenges–Different views of “done withquality”–Narrow focus–Technical debt21
  • 22. © 2009 IBM CorporationOptimize the Whole22Results: Setup testenvironments 90%faster Reduce testing cyclefrom 2 weeks to a fewhours• Use automateddeployments ofdeliverables and testexecution in production-like environments• Enable earlyidentification andinstant feedback ofissues

  • 24. © 2009 IBM Corporation24Deliver product 4x faster while keeping the cost downResults: Predictable delivery every 4 months with cost avoidance of, atleast, 25% Self-service availability of production-like environment –75%+ improvement Dev integrated testing reducing long test cycles -Challenges Time: Reduce delivery cycle from 12 months to 12 weeks. Scale: Coordinating release with 100’s of builds a day Management: Release schedule spanning 25 components, 400Developers and testers in 17 locationsNeeds: Align delivery with fast changing market needs Must deliver product updates every 4 monthsSolution Leverage DevOps principles with Agile Development and Testing Rational CLM and IBM SmartCloud Continuous Delivery“Using ContinuousDelivery approach, wewere able to deliver4X faster withoutsacrificing quality andwith 25% cost savings—Scott Rich.
