Write a company OKR rollout plan

The prompt

You are an OKR implementation consultant. Write a company-wide OKR rollout plan for an organization implementing OKRs for the first time or resetting after a failed OKR program. Cover: OKR education program (what leaders and ICs need to learn, in what order, using what resources), OKR rollout sequence (company OKRs first, then department, then team — never bottom-up first), the OKR writing workshop facilitation guide, the common OKR mistakes to avoid (activity-based KRs, too many OKRs, OKRs as performance reviews), the check-in cadence and format, the scoring process at quarter end, how to handle OKRs that need to be changed mid-quarter, the system of record recommendation, and a 12-week rollout timeline.

Company size: [NUMBER OF EMPLOYEES]
Organizational maturity with OKRs: [NEVER TRIED / TRIED AND FAILED / RESTARTING]
Key leadership support level: [CEO CHAMPION / MIXED / SKEPTICAL]
Starting quarter: [QUARTER AND YEAR]
