  1. The Road to Agile From the Bottom Up Kevin Malley Tracey Clark TQ2012 April 23rd, 2012

  2. Agenda • Overview • Why change and how • What worked • What had to change • Signs of danger • Summary of benefits • Where we are headed • Conclusion TQ2012

  3. Overview • Project was managed as Waterfall and wasn’t meeting customer expectations • Move to Agile was influenced by successes in other areas who were having the same issues • Internal Project • Stakeholders where accepting to change - opportunity for improvement TQ2012

  4. Why change • What we delivered late was: • Not what the customer wanted • Not what we had promised • Not something we where happy with • Full of unresolved defects • Same old project failure TQ2012

  5. Change #1 – Customer Involvement • Release Train • What’s ready goes what isn’t catches the next train • Product Owner (representing Customer) drives work • Involved in sprint planning • Sprint Demo • Testing Methods • Greater emphasis on exploratory testing. Run more often and earlier in the product life cycle TQ2012

  6. Change #1 – Continued • Dev and SV&V offset by one sprint • Strong collaboration between developers and testers Dev Sprint 1 Test Sprint 1 Dev Sprint 2 Test Sprint 2 Dev Sprint 3 Regression Sprint TQ2012

  7. Lessons learned change #1 • Benefits • Customer happier (Involved in sprint planning and demo) • Less margin of error in release dates • Closer relationship between Dev and Test • Exploratory tests yield quick results and could form basis for regression test scripts • Pitfalls • Defects could take 4 weeks to see a resolution • Rapid maintenance turn around • Testing reliving design weeks later TQ2012

  8. Change #2 - Design • Why: • Reduce relearning of design • How: • Tester deployed into Dev Sprint • Build test cases • Run Exploratory Tests on dev builds • Tester then transitions to offset sprint to conduct formal tests Dev Sprint 1 Tester A Test Sprint 1 Tester A Dev Sprint 2 Tester B Test Sprint 2 Tester B Dev Sprint 3 Tester A Regression Sprint TQ2012

  9. Lessons learned change #2 • Benefits • Caught some issues earlier • Less rehashing of design • Pitfalls • Still unable to resolve lengthy defect turn around • Length of time to deployment not addressed TQ2012

  10. Change #3 - Time • What: • Time to release • Defect turn around • How: • Testing as part of the definition of done • Removal of offset sprints • Testing tasks tracked within User Stories • Exploratory Tests used almost exclusively during development --> Drive scripted regression tests Sprint 1 Sprint 2 Regression Sprint TQ2012

  11. Lessons learned change #3 • Benefits • Monthly releases now possible • Pitfalls • Defect metrics mean far less TQ2012

  12. What had to change • Removal of Test Plan (Emphasis on Strategy) • Adoption of Exploratory Testing • How and when we log defects • Customer commitment • Segregation of duties • Requirements and design docs became living documents within agile tools and wiki’s • Relationship between dev and test TQ2012

  13. Signs of danger – Stakeholders (Chickens) • Unclear Product Owner (Customer) • Product Owner not Engaged • Product Owner doesn’t take ownership getting necessary requirements from multiple business groups and maintaining communication throughout project with all groups • Timely decision making • Some stakeholders become over committed TQ2012

  14. Signs of danger – Core team (Pigs) • Development moves forward while impediments block testing • Development and testing can’t agree • Don’t test everything • Scrum Master not understanding their role • When is it time to make the decision to move to next release • Improper Sprint Planning – Not learning from previous sprint • Demo TQ2012

  15. Summary of benefits after changes • Customer Satisfaction • Less rework • Less variance in committed production dates • Cleaner regression runs • Quicker turn around on defects • Less defects • Stronger relationship between developers and testers TQ2012

  16. Where we are headed • Further support and understanding from Senior Management • Socialize benefits – encourage the chickens • Refining the use of Exploratory Testing • Automation • Training testers as Scrum Masters • Working out an offshore model TQ2012

  17. Conclusion • You won’t get it right the first time • The value of applying lessons learned • One size doesn’t fit all – multiple adjustments may be required • Major adjustment to normal practices and processes • Importance of roles and responsibilities TQ2012
