Gil Irizarry, Constant Contact presentation from MassTLC seminar on taking your agile development to the next level

Start with Lean Principles • Eliminate Waste • Build Quality In • Create Knowledge • Defer Commitment • Deliver Fast • Respect People • Optimize the Whole Leading Lean Software Development: Results Are not the Point by Mary and Tom PoppendieckCopyright © 2012 Constant Contact Inc. 2

Add Kanban Principles • Start with what you do now • Agree to pursue incremental, evolutionary change • Respect the current process, roles, responsibilities & titlesCopyright © 2012 Constant Contact Inc. 3

Properties of Kanban • Visualize the workflow • States in the team board are a reflection of how a team completes its work • Limit work-in-progress (WIP) • Manage Flow • Aim for continuous flow • Make Process Policies Explicit • Improve CollaborativelyCopyright © 2012 Constant Contact Inc. 4

Some tools and techniques • A value stream map to identify the work states in a process • Kanban board that has lanes mapped to the identified states • Cumulative flow diagram to chart the progress and status of work • Metrics such as cycle time to identify where to improveCopyright © 2012 Constant Contact Inc. 6

Kanban at scale • Implied in the principles is that there are no iterations. • Teams should work continuously. • However, still need software releases or other integration activity that’s often iterative. • How to address this dilemma?Copyright © 2012 Constant Contact Inc. 7

The Release Train • If a deliverable misses a release (the train), it simply waits to capture the next one • We don’t penalize a team if a deliverable is not done at the end of a release and misses the release train • Teams plan and test continuously • It’s OK if a team pulls functionality from a release within a release cycle • It’s OK if a team starts work for the next release in the current releaseCopyright © 2012 Constant Contact Inc. 8

Automation • To make this work, as much as possible needs to be automated • Automated builds upon code check-ins • Automated tests built into the builds • Automated deploys of successful builds • Automated e-mails containing results of build and test runsCopyright © 2012 Constant Contact Inc. 9

Frequent deployments • Code built but waiting to be deployed is not producing value • Shorter, frequent deployments bring value to your customers sooner • Again, automation is the keyCopyright © 2012 Constant Contact Inc. 10

DevOps (DevTestOps?) • There is a growing movement to reduce, if not eliminate, the boundaries between development and operations • Operations today looks a lot like coding. Should be scripting everything. This is called DevOps. • Some have extended the concept to DevTestOps. QA today looks a lot like software development too. The days of manually executing a test plan are over.Copyright © 2012 Constant Contact Inc. 12
