Transcript of Release wednesdays and the agile release train upload
Why talk about this?
•Successful approach on current projects•Putting releases at the heart of how we develop and deliver software•Allowing us to plan better and make better decisions•Encourage other teams to try this approach
Because…
•Give users valuable stuff quickly•Get timely feedback•Reduce risk by reducing delta between releases •Get better at releasing•Get a kick out of it
Why releases at a ‘deliberate’ cadence?
•Gives us a regular, sustainable rhythm•Keeps us honest; we need to keep build continually ready•Don’t have to think about it•Don’t overdo it
The benefits we have seen
•Users get functionality and bug-fixes quickly•No release ‘crunch’•We don’t worry about ‘when’•We are better at releasing•Work in progress is small•Our processes are healthy•The team are motivated by it
How we release every Wednesday
•Streamlined, automated releases•Small, incrementally valuable user stories•‘Master’ branch is continually releasable•Team focusses on the release cadence•Team owns release process
The what?
•Trains (releases) go out on fixed timetable•The train delivers cargo to customers•The train will not wait for you•If cargo (work) is not ready the train goes without it•Cargo waits for the next train
Why is this better than a Gantt Chart?
“Plans are useless,
but planning is indispensable”
Dwight D. Eisenhower
Why is this better than a Gantt Chart?
The Release Train is not a formal schedule to be obeyed, but a prediction that helps us make
decisions. It encourages the team to ask the right questions in order to control scope and understand timescales
throughout the project
The benefits we have seen
Team-driven planning:•Clear planning horizon•Clear current focus•Clear immediate plan• Important marketing activities/deadlines are
visible •Changes to plan are explicitly discussed•Team-driven scope management•Understand real progress towards goals
The benefits we have seen
Embeds good practice:•Keeps weekly releases•Keeps us to small user stories•#NoEstimates
It can be hard
For example:•Breaking work up into small, valuable stories is hard (but not impossible)•Watching cargo fall off the end of a train can be painful•*Just* missing a release with some cargo is frustrating•Releasing is REALLY motivational (we need to watch for burnout)
