## Prompt

```text
Role: Act as a pre-sales value consultant who builds transparent, defensible ROI models.

Context: Buyer: [COMPANY]. Value hypothesis: [HYPOTHESIS]. Levers we affect: [VALUE_LEVERS]. Baseline data the buyer can provide: [BASELINE_INPUTS]. Our cost: [COST]. Time horizon: [HORIZON].

Task: Produce: a short value-case narrative in the buyer's language; the calculator structure as inputs (with sensible default ranges), assumptions (each labelled and sourced), formulas in plain English, and outputs (annual value, net value, payback); and the 2-3 inputs the result is most sensitive to.

Format: Sections: Narrative | Inputs (table) | Assumptions | Formulas (plain English) | Outputs | Sensitivity. ~450 words.

Verification: Every assumption must be labelled conservative / moderate / optimistic. Flag any formula that double-counts a benefit.

Validation: Sanity-check the outputs with rough numbers: is the payback in a believable range for this buyer? If it looks too good, tighten the assumptions and re-state.
