Include: 1) One‑sentence product vision and the key customer problem it solves; 2) Strategic objectives (3–5) tied to measurable outcomes (OKRs or KPIs); 3) Top initiatives and epics prioritized with rationale (impact, effort, risk); 4) A quarter-by-quarter roadmap showing major milestones and releases; 5) Success metrics per initiative and how to measure them (data sources, instrumentation needs); 6) Resource and dependency summary (teams, estimated effort, external dependencies); 7) Key risks and mitigation plans; 8) A short executive summary (3–4 sentences) suitable for leadership. Use the variables to tailor the output. Where assumptions are made, list them explicitly.
