status-update has two modes. Analyze mode produces an internal delivery assessment — workstream status, risks, blockers, dependencies, and recommended actions. Draft mode produces audience-calibrated communication leading with the assessment, not a summary of activity. The output format adapts by audience: a VP gets a concise assessment with clear risks and decisions needed; a cross-functional team gets workstream-level detail with dependencies called out.
The failure mode for status updates is describing output rather than making an assessment. "We shipped X, started Y, and will finish Z next sprint" is activity. "We are on track for Android GA with one open risk: the payment edge-case bug. If it doesn't close by end of this sprint, GA slips two weeks" is an assessment. status-update enforces that distinction — it leads with delivery health and only describes activity in service of that assessment.
Day 5 closes Week 1 because communication is the output of all the prior work. You drafted, reviewed, decomposed, and planned. Now you communicate the state of that work to someone who wasn't in the room. After this week, you've run the full writing cycle: produce → evaluate → decompose → plan → communicate.
