OKR Implementation Guide

Design an OKR implementation guide for [Company] with [Employee Count] employees. Include: 1) OKR fundamentals — what makes a good Objective (inspirational, qualitative, time-bound) and Key Result (measurable, specific, challenging but achievable). 2) Rollout strategy — Phase 1: executive team only (Q1), Phase 2: department level (Q2), Phase 3: team level (Q3), Phase 4: individual level if appropriate (Q4). Don't try to do everything at once. 3) Alignment architecture — company OKRs → department OKRs → team OKRs. Maximum 3-5 objectives per level, 3-5 KRs per objective. Show how to cascade and avoid 'waterfall OKRs'. 4) Writing workshop — facilitation guide for OKR writing sessions, common mistakes (KRs that are tasks, objectives that are too vague), before/after examples for 5 departments. 5) Scoring and grading — 0.0-1.0 scale, sweet spot at 0.6-0.7, how to differentiate committed vs aspirational OKRs. 6) Review cadence — weekly check-ins (15 min), monthly progress reviews, quarterly grading and retrospective, annual planning. 7) Common failure modes — too many OKRs, OKRs become task lists, no check-in rhythm, punishing missed stretch goals, ignoring BAU work. 8) Tools — comparison of Lattice, Culture Amp, Ally.io, Gtmhub, simple spreadsheet template. 9) Change management — executive sponsorship requirements, OKR champion program, training materials, FAQ for skeptics.
