Continuous Delivery Maturity Model

Download to read offline

Continuous Delivery presents a compelling vision of builds that are automatically deployed and tested until ready for production.

Most teams aren't there yet. Some never want to go that far. Others want to push the envelope further.

This deck presents a model for scoring yourself on the continuum and examples of how companies can decide what parts of CD to adopt first, later and not at all.

Continuous Delivery Maturity Model

  1. 1. Continuous Delivery Maturity Model Eric Minick, Lead Consultant 1
  2. 2. Eric Minick Lead Consultant • 8 Years at Urbancode • Commits on three generations of UC products • Experience as a Dev, Tester and build guy • Currently focused on best practices and industry trends 2
  3. 3. The plan for today • Short Intro to Continuous Delivery • The Maturity Model – Building, Deploying, Testing, and Reporting • Applying the Model: Personas – El Emeno Investments: Balancing agility and control – All-Green United Systems: Large scale Scrum – Diversity Handhelds: Dozens of platforms • Additional Resources and Q&A 3
  4. 4. The plan for today • Short Intro to Continuous Delivery • The Maturity Model • Appling the Model: Personas • Additional Resources and Q&A 4
  5. 5. CI: it’s about Quality Determination • Integrating frequently is less painful than infrequently. – But, If we commit frequently blindly, we have a broken code base • Implied condition: each integration will not decrease the code quality. – This is the key to CI – The rest is implementation details. 5 http://www.urbancode.com/blogs/anthillpro- blog/2011/09/07/continuous_integration_why_you_dont_really_get_it.html
  6. 6. Continuous Delivery: Beyond the Team Build • Continuation of the Quality Determination • Functional tests require deployment. • Progression through environments on a march to production, with “the build” subjected to more exhaustive tests in each environment. • Beyond the functional team, but also across projects Build & Deploy to Functional Deploy to Integration Deploy to Deploy to Unit Test DEV Tests SIT Tests UAT PROD 6
  7. 7. Why a CD maturity model? • How mature are our Build, Deploy, Test practices? • Where can we get the most improvement based on our specific problems and needs? • How are other organizations solving these same problems? “The future is here. It’s just not evenly distributed yet.” – William Gibson 7
  8. 8. Maturity Model: Parts and personas Building, Deploying, Testing, and Reporting – Base, Beginner, Intermediate, Advanced, Extreme • Industry Norm vs. Target – What do we see most people doing today? – A general target to shoot for (and how to pick a good target for your own team) 8
  9. 9. Poll: Our CI or CD system handles: • Building our code (at least daily) • … and deploying after build • … and testing after deployment • … and reporting across building, deploying and testing • … and more! • We have no CI system 9
  10. 10. Building 10
  11. 11. Deploying 11
  12. 12. Testing 12
  13. 13. Reporting 13
  14. 14. Standard Target Based on this model, the standard target is: • Continuous builds on a distributed grid using dependency management • Builds automatically deployed to first test environment • Build runs extensive unit tests; extensive functional tests automatically executed in test environments • Test results and trends are widely visible and available • Information from the build system informs manual risk-based testing • Self-service deployments to other environments – Those deployments coordinated between tiers / services 14
  15. 15. The plan for today • Short Intro to Continuous Delivery • The Maturity Model • Appling the Model: Personas • Additional Resources and Q&Aof platforms 15
  16. 16. Apply the maturity model: Personas El Emeno Investments: Balancing agility & control All-Green United Systems: Large-scale Scrum Diversity Handhelds: Dozens of platforms 16
  17. 17. Poll: Our main problem we hope CD can help with is: • Improving our delivery speed • Improving quality and compliance • Supporting multiple platforms or devices • Multiple of these • We have other problems • We have no problems 17
  18. 18. El Emeno Investments Trading system for securities – Time to market is a key competitive advantage – Strict legal requirements & audits Problem: slow heavyweight process – Numerous sign-offs, handheld deployments, lengthy manual test cycle – Pressure to work overtime to compensate – Late mistakes in deployment – High turnover “How do we balance agility and control?” 18
  19. 19. El Emeno Investments: Deploying Needed automated, traceable deployments – Secure push-button deployments – Deploy to production Benefits – Self-service deployments to test take pressure off release engineers – Using uniform automated deployments reduces errors & delays – Security and traceability make auditors happy Advanced level deployments 19
  20. 20. El Emeno Investments: Building Needed Audit Proof Builds – Automatic, Controlled Build Process – Builds stored in an artifact repository (ITIL: Definitive Software Library) Benefits – Clear understanding of what is in each build lowers risk – Supports accurate deployments by guaranteeing no changes to tested artifacts – Faster approvals and audits with lower risk of failure Beginner level builds with some Intermediate practices 20
  21. 21. El Emeno Investments: Testing Needed Rapid Regression Testing and Security – Automated unit tests of core functionality on all builds – Automated security scans of select builds Benefits – Less time on manual regression testing allows quicker detection of problems in new functionality – Security scans lower business risk, increasing compliance Beginner level testing with advanced security scans 21
  22. 22. El Emeno Investments: Reporting Needed historic release information, consolidated reports – Audit log of who deployed what build where – Produce test, security scans, approval logs for releases Benefits – Consolidating reports yields faster, easier audit compliance – Easy review of a build’s history reduces deployment errors – Risk is more easily assessed Intermediate level reporting 22
  23. 23. El Emeno Investments: Results “How do we balance agility and control?” – Time to market is a key competitive advantage – Problem: slow, heavyweight process “Our continuous delivery system provides us an end-to-end automation across our build lifecycle. We now have a faster cycle time, fewer manual errors and an easier time in audits.” 23
  24. 24. All-Green United Systems Large global IT with business critical applications – Large scale scrum with cross-functional teams – Traditional integration QA & release engineering – Recent move to SOA Problem: releases are a bottleneck – Legacy “big bang” release process – Lack of synchronization across applications creates backlog – QA finding cross-team problems in integration testing – Apps fail in product, after appearing to work in QA “How do we realize the benefits of Scrum in a large organization?” 24
  25. 25. All-Green United Systems: Building Needed unification of build systems across scrum teams – Consolidate from numerous build systems to one build grid – Dependency management between components – Scrum of Scrums yields Build of Builds Benefits – Build grid more efficiently uses hardware, lowering costs and improving response time – Build of Builds more quickly detects cross-team integration problems and improves component traceability – Single build system lowers learning curve when switching scrum teams Intermediate level building 25
  26. 26. All-Green United Systems: Deployments Needed to speed the release process to keep pace – Automated release across teams and environments – Coordination of SOA releases – Deploy what was tested – New applications with extensive testing using continuous deployment to production Benefits – Unified deployment scripts avoid errors in production – Self-Service deployments remove burden from release engineers – Continuous deployment give some systems maximum throughput Advanced and Extreme level deployments 26
  27. 27. All-Green United Systems: Testing Needs vary by scrum team and application – Investment in expanded automatic testing focused on mission critical, frequently changing, and new applications – Component interfaces gain automated regression tests Benefits – Fewer breakages in shared components improves developer productivity – Mission critical applications gain stability, lowering risk of costly defects Varying levels of testing 27
  28. 28. All-Green United Systems: Reporting Needed better visibility between cooperating small teams – Consolidated build systems put all build information in one place – Include test and deployment reports in CD system – Trend report results Benefits – Reduced coordination overhead between scrum teams – Single report repository improves coordination between development and testing – Trending improves the scrum team’s understanding of how done they are Advanced level reporting 28
  29. 29. All-Green United Systems: Results “How do we realize the benefits of Scrum in our organization?” – Large scale scrum with cross-functional teams – Problem: releases are a bottleneck “Our continuous delivery system allowed our small, globally distributed scrum teams to cooperate in large system builds automatically. By keeping the code integrated we eliminated late errors, improved coordination across teams, and eliminated our release bottleneck.” 29
  30. 30. Diversity Handhelds Software platform for mobile devices – Partners work with device manufacturers – Each product ported across a wide range of platforms Problems: breaking existing ports & tracking build content – Porting to a new platform might break an inactive port; hard to track down cause later – Tracking deliverable contents manually is time consuming; hard for support to find information when needed “How can we reduce the cost of adding a new platform?” 30
  31. 31. Diversity Handhelds: Building Needed regular builds of many build configurations – Diverse, multi-platform, multi-tool chain build farm – Regular, automatic builds for all configurations – Upload of build product into build artifact repository Benefits – Building all configurations at least daily saves developer time with quick detection of platform specific compile problems – Support has easy access to builds delivered to customers – Automated Bill of Materials tracking reduces manual effort and errors. Intermediate level building 31
  32. 32. Diversity Handhelds: Testing Needs automated cross-platform testing – Extensive unit testing run regularly – Automated functional tests run in available, representative device simulators – Static analysis and security checks regularly run Benefits – Faster defect detection with shorter QA cycles leading to improved time to market – Lower risk of potentially expensive platform specific defects – Manual testing can find deep bugs rather than focus on smoke testing dozens of variants Advanced level testing 32
  33. 33. Diversity Handhelds: Deployments Needed deployments to simulators to support testing – Scheduled deployments integrated to build management and testing Benefits – Advanced testing that provides rapid feedback from functional testing is dependant on basic deployments Intermediate level deployments 33
  34. 34. Diversity Handhelds: Reporting Needed to understand stability and historical information – Gather build, various testing and release logs centrally – Align reports to individual builds – Maintain reports related to released builds through that version’s end of life Benefits – Provides data to support and engineering regarding what was tested on old releases customers have problems with – Lowers effort in understanding test results for wide array of platforms / configurations Advanced level reporting 34
  35. 35. Diversity Handhelds: Result “How can we reduce the cost of adding a new platform?” – Partners work with device manufacturers – Problems: breaking existing ports & tracking build contents “Ourcontinuous delivery system handles our wide-range of platforms and prevents our ports from going stale. Our bill-of-materials is now generated automatically and our support people can access historical information any time.” 35

Editor's Notes

  • CI is based on the observation that the longer development streams diverge, the more painful the eventual integration will be. Taking the converse of the above statement, the more frequently developers integrate their changes, the more painless those integrations will be
