Seriously? Even without knowing any context, there’s a handful of universal best practices that had to Swiss cheese fail for this to even get handed off to devtest…
- Why are you adding/changing feature flag changes the day before handoff? Is there process for development freeze before handoff, e.g. only showstopper changes are made after freeze? Yes but aales asked for it so they could demo at a conference. Why don’t we have special build/deployment pipeline for experimental features that our sales / marketing engineers are asking for?
- Was it tested be developer before pushing? Yes - why did succeed at that point and fail in prod? Environment was different. Why do we not have dev environment that matches prod? Money? Time? Politics?
- Was it code reviewed? Did it get an actual review, or rubber stamped? Reviewed, but skimmed important parts only — Why was it not reviewed more carefully? Not enough time — why is there not enough time to do code reviews? Oh, the feature flag name used underscore instead of hyphen — why did this not get flagged by style checker? Oh, so there’s no clear style conventions for feature flags and each team does their own thing…? Interesting…
Etc etc.
