technical-design

Technology-neutral technical design process - writing a design doc with problem, goals and non-goals, constraints, options considered with trade-offs, chosen approach, risks, rollout and rollback, testing and observability plan, open questions, and review; sizing the design to the change from one-pager to full doc; using spikes to retire uncertainty; and an inline template. Load when planning a non-trivial feature or change, writing or reviewing a design doc, comparing implementation options, or planning a rollout.
