Session Title : Alice in DevOps Land- An exploratory journey Abstract: This session will provide Persistent Systems view on DevOps which includes the fundamentals of Continual Integration, Continual Testing, Continual Deployment and Continual Learning. An important aspect of every Lean journey is the mindset of people which would be detailed out here. A case study covering the DevOps transformation journey of one of the programs in the organization will be covered here. The audience would be walked through the challenges faced and the program’s exploratory journey leveraging Lean Kanban principles. This session would also cover how the lean culture is practiced and promoted at Persistent.

Team wanted to use DevOps to help build the pipeline so that the POCs
could get converted to projects faster. What was stopping them?
DevOps was a maze for them. Too many things and too much to do

Our Learnings:
 Visualizing the workflow using simple post-its with WIP limit
 Incremental, evolutionary change with continual improvements
 Feedback and learning from failures
 Lean/Kanban mindset of the leadership
Sprint Level Metrics Before After Remark
Time takenfor build 1 hour 8-10 mins
Time takenfor unittesting(commitstage) 8-10 mins (part of CI) There were no test cases before
Benefits and Learnings from this Journey so far…
Minimal Cycle Time for CI implementation for the new project initiated.
