  • 1. Welcome to the PDU session on “Challenges on Agile projects” Bhawani Nandan Prasad
  • 2. Objectives  Differences between traditional methods and Agile  Challenges on Agile projects Caused by Agile or Exposed by Agile? Integration challenges on complex projects Dealing with technical debt Blocking issues Education of stakeholders Heavy R&D and design requirement Support distractions  Summary  Q&A Bhawani Nandan Prasa
  • 3. Differences in traditional and Agile methods  Agile relies on incremental and iterative development  A deliverable is produced every few weeks (1-4 weeks) at the end of the iteration  All the engineering activities need to completed within the time-box of the iteration  Code at the end of the each iteration needs to be “near releasable”  After certain number of iterations (when substantial value is created), the release concludes Bhawani Nandan Prasa
  • 4. Caused by Agile or Exposed by Agile?  Ask the question – is this challenge “caused by Agile” or is it “exposed by Agile”?  Examples: Unreliable estimates Distributed teams Immature teams  Agile does not fix all the dysfunction – but it will expose it sooner! Bhawani Nandan Prasad
  • 5. Multiple teams; Integration challenges  What is the challenge? Dependencies between teams need to be coordinated Integration between teams as they are in parallel development  Caused by: Agile teams are small Large products or applications will have multiple teams working in parallel Bhawani Nandan Prasad
  • 6. Multiple teams; Integration challenges  How to address? Call out dependencies early and plan ahead Plan for buffers for any hand-offs (“look ahead planning”) Publish interface definitions and integrate using mock interfaces Automated tests to validate integrations frequently Bhawani Nandan Prasad

  • 8. Technical debt  What is the challenge? Work that needed to be done during the iteration did not get done E.g. All tests did not run, defects pending All the debt accumulates till the end  Caused by: Running out of time while trying to complete features Tendency to claim success even when it is not complete Bhawani Nandan Prasad
  • 9. Technical debt  How to address? Define clear “Done criteria” and adhere to it strictly Plan for periodic “stabilization” or “hardening” iterations to remove technical debt  But resist the temptation to rely too much on “hardening”! Be transparent about the existence of debt  Plan for metrics and thresholds Bhawani Nandan Prasad
  • 10. Iteration “done” criteria (example)  Software with all features work as defined by the user story  All QA testing for completed features is done with no pending defects Regression tests pass  All documentation is completed  Planned stories demonstrated to the Product Owner, Customer and other stakeholders Copyright (c) Sandeep Shouche, PMP, PgMP, PMI- ACP, CSM
  • 11. Blocking issues  What is the challenge? If the team gets blocked by any issue (even for a few hours), the success of iteration is compromised  Caused by: Iterations are very short – not much time to recover  How to address: Encourage team to bubble up blockers quickly Scrum Master/Project Manager needs to be pro-active in tracking these issues Bhawani Nandan Prasad
  • 12. Education of stakeholders  What is the challenge? The team follows Agile principles, but they are not supported by other stakeholders; e.g. Unrealistic expectations, top-down management  Caused by: Everybody having different expectations from the methodology  How to address: Give quick primer/introductory Agile training for the stakeholders Do NOT use Agile if customer and management are not on-board Bhawani Nandan Prasad
  • 13. Requirements intensive on design, R&D  What is the challenge? Some requirements are complex and/or require a lot of R&D It takes a while to design the basic framework for a system  Caused by: Iterations may be too short to absorb the R&D and design activity  How to address: Spend time on analysis and design but time-box it (write research or SPIKE requirements) Get used to “just-enough” and evolving design Bhawani Nandan Prasad
  • 14. Support workload disrupts development  What is the challenge? As the team is working on a new version, they are distracted by issues and defects from the previous version (support issues)  Caused by: Support activity tends to be ad-hoc by nature and can disrupt iteration schedule  How to address: Reserve time for support activities Form a dedicated “sustaining” team to ring-fence and protect development activity Bhawani Nandan Prasad
  • 15. Summary  When you encounter an issue or challenge while working on an Agile project, first ask yourself the questions – “Is this caused by Agile” or “Did Agile expose this”  There is always a way to tweak the methodology to help address an issue – process tailoring is required  Use the methodology as a “starting methodology” and evolve your own based on what works for you  But make use of discussion forums and available sources of guidance before re-inventing the wheel! Bhawani Nandan Prasad
