Bug Triage

The regular, disciplined meeting where new defects are reviewed, classified, prioritised and assigned — the difference between a live product backlog and a graveyard of unresolved tickets.

The habit of upgrading libraries and frameworks in small, continuous, bot-assisted steps — so security patches land in days and the dreaded 'big-bang upgrade' never has to happen.

Letter D · Updated 2026-07-14

Deployment Freeze Window

A pre-agreed period during which no non-emergency changes reach production — the operational discipline that protects a business's most exposed hours from avoidable engineering risk.

Letter F · Updated 2026-08-21

The discipline of measuring, quarantining and fixing tests that pass and fail without any code change — before the team learns to ignore red builds and ships a real regression past them.
