Field notes
Short pieces from assessments and retainers — written for release owners who live with deployment frequency, rollback rates, and reliability day to day.
When deployment frequency and rollback rates disagree
Rising ship counts look healthy until reverse deployments climb in the same window. Here is how to read that tension without blaming a single team.
Sampling releases instead of worshipping averages
Averages hide the awkward releases. Sampling a handful of real ships — good and bad — gives assessment conversations something solid to stand on.
Rollback criteria that survive a stressful night
Criteria written in calm daylight often fail at 02:00. We sketch language that ties rollback decisions to observable reliability signals.
Reading reliability after a quiet deploy
Green pipelines and calm chat channels can hide slow reliability erosion. A short post-deploy reading habit keeps frequency honest.
