# Build Business Case
Create a decision model the buyer can inspect and challenge. A business case is not proof that value will occur.
## Inputs
Read `.agents/gtm-context.md`, discovery and outcome evidence, the deal plan, usage or process data, approved pricing, implementation scope, buyer alternatives, and any finance guidance. Establish the audience, decision, time horizon, currency, accounting perspective, and authoritative sources.
If inputs are incomplete, build the smallest useful model with formulas, unknowns, break-even questions, and a validation plan. Do not fill gaps with generic benchmarks.
Read [the business-case methods](references/methods.md) before calculating ROI, TCO, payback, capacity, revenue, or present value. Use [the business-case template](assets/business-case.md).
## Workflow
1. Define the buyer decision, audience, scope, horizon, currency, and comparison date.
2. Create an evidence ledger for every material input. Separate `Verified`, `Reported`, `Inferred`, `Hypothesis`, `Unknown`, and `Contradicted` claims.
3. Compare credible alternatives: current state, delay, internal change, competing approach, and the proposed solution where relevant.
4. Map operational changes to economic drivers. State the causal chain and attribution boundary; do not count the same benefit twice.
5. Model incremental costs, including subscription, implementation, buyer effort, change management, ongoing operation, risk, and opportunity cost when supported.
6. Build
