# PRD outline — skeleton

*Headings and field lists only. Re-typed from the structure used on a sovereign OSINT platform built
for a defence innovation challenge; no content from that or any other project.*

**Header block:** product · MVP number and name · version · date · owner (by role) · status (draft /
reviewed / approved) · links to the master spec, the eval framework and the success metrics

## 1 · Problem statement
- Who has the problem, in one sentence per actor
- The number that proves it, with its source, or `[TBD]`
- What happens today without the product

## 2 · Scope and non-goals
### In scope (this MVP)
- One line per capability; each maps to at least one user story below
### Non-goals (binding)
- What this MVP will **not** do, and why; a non-goal is changed only by a new PRD version
- Declined risks from the risk register land here with their reason

## 3 · Actors
| Actor (by role) | Goal | Trust level | Negative case (what they must not be able to do) |
|---|---|---|---|

## 4 · User stories with acceptance criteria
*Grouped by capability. Each story carries: ID · as-a / I-want / so-that · acceptance criteria as
observable checks · the NFR it depends on · the eval case it creates, if any.*
### Capability group A
### Capability group B
### Candidate stories — surfaced, not committed
- Stories heard and recorded, explicitly out of this MVP, so they are neither lost nor implied

## 5 · Functional requirements
| ID | Requirement | Story it serves | Verification (test, demo, inspection) |
|---|---|---|---|

## 6 · Non-functional requirements
| ID | Dimension | Target | Measured how | Measured when (before sign-off) |
|---|---|---|---|---|

*Dimensions for an AI product include: latency (P50, P95) · abstention rate on unanswerable inputs ·
citation validity · availability in the target environment (e.g. air-gapped) · data residency ·
explanation coverage · resource ceiling (memory, CPU) · auditability*

## 7 · Metrics hook
- Which KPI in the success-metrics document this MVP moves
- Which guardrail metric must not degrade
- Which eval floor this MVP must clear, by reference to the eval framework

## 8 · Open questions and risks
| ID | Question or risk | Owner (role) | Decision needed by | Register reference |
|---|---|---|---|---|

## 9 · Traceability appendix
| Story | Functional reqs | NFRs | Eval cases | Test IDs | Sign-off entry |
|---|---|---|---|---|---|
