M2 design-partner closure and readiness decision

Problem

Own the M2 closure artifact: verify internal-adoption and design-partner readiness, maintain the operating checklist, track remaining gaps to owners, and record the explicit readiness decision with risks and next actions.

Context

The milestone pages define exit criteria and KPI targets, but closure work is often distributed across many implementation tasks. Without one explicit owner for milestone closure, weekly triage cadence, runbook/checklist updates, owner-based gap tracking, and final go/no-go evidence can remain implicit and drift until the deadline.

Possible Solutions

Recommended: assign one milestone-closure owner and one explicit closure artifact instead of relying on implicit status spread across many task files.

Plan

1. Review the milestone exit criteria and KPI targets against current implementation tasks and evidence. 2. Build and maintain the milestone closure checklist and operating cadence. 3. Track all remaining gaps, risks, blockers, and owners in one place. 4. Publish an explicit readiness or disposition decision with risks, exceptions, and next actions.
