In Agile Development, Testing is meant to be a part of the development process, right along with coding, but many “Agile Teams” are missing this vital component and experiencing degregated quality. In this presentation, we will discuss how to integrate Agile Testing in Kanban processes by discussing the following:

• Introduction to Agile and Lean
• How testers add value to cross-functional Agile Development Teams

• How testers participate in Agile ceremonies
• How to test in an Agile Environment
• The Four Environments (Dev, Test, Stage, Production)
• The types of testing that occurs in each environmen

  5. 5. Copyright 2015, cPrime Inc. 5 Adaptive Spectrum Drives Process Selection Scope Uncertainty + Effort Uncertainty: PREDICTIVE ADAPTIVE REACTIVE Plan-Driven Scrum Kanban Waterfall The Agile Zone • Emphasize adaptability to rapid change • Enable detailed short- term planning • Evolve longer-term specs, plans over time • Overhead of enabling change is costly for predictable work • Emphasize continuous re-prioritization, efficient allocation of work to people • Do not require work to be planned against calendar • Handle unpredictable work well • Emphasize efficiency (minimum cost, duration) • Perform well when work is well understood • Perform poorly when uncertainty is high 5
  6. 6. Copyright 2015, cPrime Inc. 6 What is an Agile Process? Any process that adheres to the principles of the Agile Manifesto We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more. Manifesto for Agile Software Development, www.agilemanifesto.org The concepts arose in software project management, BUT… Change “software” to “products” or “deliverables” to apply more generally 6
  7. 7. Copyright 2015, cPrime Inc. 7 Agile is Lean* 1. Optimize the whole (value of complete solution, product) • Consider big-picture, long-term as well as parts, short term 2. Eliminate waste • Maximize amount of work not done  Minimize non-product effort (documents, sign-offs)  Defer decisions, work: YAGNI 3. Build Quality In • Definition of Done, XP practices 4. Learn Constantly • Feedback loops (external, internal) 5. Deliver Fast • Short cycles, incremental delivery 6. Engage Everyone • Group expertise / Wisdom of Crowds** 7. Keep Getting Better • Retrospectives *www.poppendieck.com **© 2004 James Surowiecki, Anchor Books 7
  8. 8. Copyright 2015, cPrime Inc. 8 What is Kanban? • Kanban Japanese for Signal Card • Pull system for work flow • Originated from Toyota Manufacturing  Signals up-stream to produce more • Implemented as part of the Lean Software Movement • An agreed upon system for capacity matching • Visualization of work flow • Less overhead than traditional Scrum • Worked is pulled in as capacity is available
  9. 9. Copyright 2015, cPrime Inc. 9 Kanban Terms • Lead Time – Time from Feature Request to completion (i.e. elapsed time) • Cycle Time – Time to finish the task (i.e. time per unit) • Throughput – Amount of work delivered in a time frame • WIP – Work in Process • Swarm – Collaboration to reduce bottlenecks
  10. 10. Copyright 2015, cPrime Inc. 10 How does Kanban Work? • Forces the team to visualize WIP (Work in Progress) • Via Kanban board • Constrained by WIP • WIP limits cannot be exceeded – No work is pulled unless a slot is available • Flow of cards (work) through the system • Identify the bottlenecks and optimize • Based upon Little’s Law from Lean Manufacturing • CT = WIP/Throughput • Lower CT = Less Lead Time
  11. 11. Copyright 2015, cPrime Inc. 11 Card Wall/Kanban Board
  12. 12. Copyright 2015, cPrime Inc. 12 Walking the Kanban board • Different color post-it notes can mean different things • Priority, bugs, defects • Class of Service – priorites, severity, due dates, etc. • Left to right process flow • Enables visualization of bottlenecks • Post-it notes typically has: • Description, assignment, <due date> • Backlog is prioritized on demand by product owner
  13. 13. Copyright 2015, cPrime Inc. 13 How does it work with Software and IT Systems? • The first virtual Kanban system for software engineering was implemented at Microsoft • In IT work we often use a virtual kanban system • Tools e.g. JIRA, Lean Kit, etc. • no actual physical card is passed around to define the limit to work-in-progress • Helps to implement incremental process improvement • Kaizen
  14. 14. Copyright 2015, cPrime Inc. 14 Differences from Traditional Scrum/Agile • Less Planning overhead • If a card is available and it doesn’t exceed WIP, pull it. • Planning on demand/as needed • No estimating. WIP is the constraint • Focus on the work and improving the system • Still have daily standup which provides focus on work flow through the system and resolving bottleknecks • No time box!
  15. 15. Copyright 2015, cPrime Inc. 15 ScrumBan? • Kanban combined with Scrum process and structure • Ideal for predictable planning and release periods • Regular planning and grooming sessions • Combination of metrics • Burndown and CFD • Regular Kiazen sessions • Time boxed
  16. 16. Copyright 2015, cPrime Inc. 16 Why use it? • Trust is event driven and that small, frequent gestures or events enhance trust more than larger gestures • Demand can be balanced against throughput with a pull system • Pull systems expose the bottlenecks and create slack in non-bottlenecks • Reduces system variability • Reducing variability allows reduced Kanban tokens, less WIP, and results in reduced average lead time • Transparency on both work and process • WIP Limits and class of service leads to empowerment
  17. 17. Copyright 2015, cPrime Inc. 17 Lean Metrics • WIP (Work in Progress) • How many cards can we handle? • CFD (Cumulative Flow Diagram) • Focus on how to reduce lead time • leverage point for improving quality is to reduce the quantity of work-in- • Little’s Law • Lead Time = Cycle Time * WIP • Cycle Time = WIP/Throughput • Focus on the work • NOT the worker

  19. 19. Copyright 2015, cPrime Inc. 19 How do Testers Add Value in Agile and Lean? • Who’s responsible for testing? • EVERYONE! – Paradigm Shift • Developers need to ensure their code is high quality, BEFORE giving it to test • XP – TDD, Pair Programming, etc. • Testers are part of the Cross-Functional Development Team • Participate in all ceremonies, including estimation • Testers create test plans and scripts while developers code • Map the testing states to the Kanban board

  23. 23. Copyright 2015, cPrime Inc. 23 Defects • Don’t have them! • Not realistic • Solid Definition of Done • Will slow down the throughput of the system • Stories/Tasks are not complete if tests are failed • It is valuable to determine where defects are found • Development, Test, Staging, and Production • Establish Defect Feedback Loop • Defects found should result in new automated tests • Product Owner and teams work together to prioritize • Which defects have to be fixed now and which can wait?
  24. 24. Copyright 2015, cPrime Inc. 24 Agile Principle #7 – Working software is the primary measure of progress • Good coding practices • Separation of Concerns • SOLID, GRASP • TDD – test first strategy • ATDD - vetting and automating acceptance criteria • Continuous Integration • Hardening sprints • Agile Requirements Modeling • Agile testing metrics

  26. 26. Copyright 2015, cPrime Inc. 26 Software Quality Metrics • Defect Tracking System • Number of defects • Location/Identification • Cyclomatic Complexity • Number of unit tests • % of unit test coverage • Code Coverage • Number and % of automated tests • Number of refactors
  27. 27. Copyright 2015, cPrime Inc. 27 IMPORTANCE OF TESTING IN AGILE • Advocate for the End User • Making sure the right thing is built • Visibility to what, how, and why something was tested • Not testing is costly – 50% of software goes untested costing US economy $60B / year* *Source: http://www.codeguru.com/blog/category/programming/the-cost-of-bugs.html
