PROFESSIONAL PRACTICE AND COLLABORATION

KEY TERMS REVIEW Governance team: the team that owns rules about permissions, data, and approvals. Observability team: the team that owns tracing systems and dashboards. Design-decision document: a short record of why a choice was made. Postmortem: a blame-free written review of an incident. Changelog: a list of changes between versions of a tool. CHECK YOUR UNDERSTANDING • Why get governance sign-off before writing code? ◦ Answer: Because rebuilding after a late rejection costs far more, and early review treats the team's concerns as design input. • What are the four parts of the design-decision template? ◦ Answer: Problem, Alternatives Considered, Chosen Approach, and Reasoning. • What makes a postmortem blame-free? ◦ Answer: It focuses on what happened and how to prevent it, not on punishing a person. • Why use a fixed weekly schedule for reading updates? ◦ Answer: A fixed schedule makes the habit reliable, whereas reading whenever you remember leads to gaps. • What three parts make a good status update? ◦ Answer: What is done, what is next, and what is blocking progress.
