Business Case Template for Product Strategy

Two to four pages. Executives do not read 20-page business cases. If your business case exceeds 4 pages, move the detailed financial model and risk analysis into an appendix and keep the main document concise. The executive summary alone should be enough to make a preliminary decision.

Focus on cost savings, efficiency gains, or risk reduction instead. Not every business case has a direct revenue line. "This saves 200 engineering hours per quarter" or "this reduces the probability of a compliance violation from 15% to 2%" are valid business justifications. Use the [ROI Calculator](/tools/roi-calculator) to model cost-based returns.

Only if competitive pressure is part of the "why now" rationale. A sentence or two in the Market Opportunity section is sufficient: "Competitor X launched this capability in Q1. Three enterprise prospects cited it in recent evaluations." For a full competitive deep-dive, create a separate competitive analysis document and link to it.

The approval level depends on the investment size. At most companies: under $50K or 1 person-month is PM + Eng Lead approval. $50K-$250K or 1-4 person-months requires VP approval. Over $250K or 4+ person-months requires C-level or board approval. Check your company's delegation of authority matrix.

Ask for specific feedback. Was the problem not compelling? Were the financials unconvincing? Was the timing wrong? Most rejected business cases can be resubmitted after addressing the feedback. Common fixes: stronger quantification of the problem, more conservative financial projections, a phased approach that reduces initial investment, or better competitive evidence. The [TAM Calculator](/tools/tam-calculator) can help strengthen market opportunity arguments. ---
