Code Inventory and Tracking Releases
A couple of years ago, I showed you how to Visualize Small Batch Sizes with Git
by plotting day-to-day the amount of changed source code lines that
hadn’t yet been released to production. While this graph gave immediate
feedback about the “drift” of development from operations (live), it’s
not something easily digested by upper management. What do these guys
really care about? It’s all about the releases silly!
Commits are “Units of Work”
Easily understood and very simple to calculate.
What was in the release?
Clicking on the release shows Pivotal Tracker stories worked on and the actual commit revision ID in github.
The PT story types also give a good indication what the main work type was – user features, chores or bugfixes.
Cause and Effect
Now you’re able to show quite clearly to the organization how often you do releases (and even what your releasing). If tagging releases is ‘crawling’, then you are now at the ‘walking’ phase. What would it take to really stretch our legs out and get ‘running’?
Showing the impact of a release is the next logical step. Did you manage to grow traffic? Has the response time of the site improved? See any more bugs after the release? These are all fairly easy to track, and plotting them as a backdrop to the releases demonstrates the real impact your team is having on the bottom-line.
What other metrics make sense here? What would you expect to see? And what would really be kick ass? Share your thoughts on twitter using the #codeinventory hash tag!
