Contractor Mini‑PRD: A 1‑Page, Build‑Ready Spec Contractors Can Implement in 48 Hours

Contractors don’t have the institutional context your full-time team does. A long, ambiguous PRD increases back‑and‑forth and context switching; a compact, implementation‑focused spec reduces it. One‑page PRDs are widely recommended for fast teams because they force clarity on scope, outcome, and acceptance before work begins.

For contractor work you must go further than a one‑pager that describes intent — you need explicit acceptance criteria and test artifacts so the contractor knows when the job is done. Contracts and procurement guidance also emphasize objective acceptance to avoid disputes and rework.

Design the mini‑PRD so a contractor can open it, understand the job, and start coding. Use these seven concise sections: Title & owner, JTBD statement, scope (in/out), UX mock(s), acceptance tests (pass/fail), telemetry & rollout checks, constraints & deliverables.

Each section should be one or two lines except mocks and acceptance tests. Keep language imperative — describe observable behavior and the exact queries or checks needed to prove success. Where necessary, link to longer docs (APIs, style guide) but don’t bury the acceptance criteria in separate files.

Acceptance tests are the contract’s heartbeat. Each test should be an input, an action, and an observable outcome — written so QA, a contractor, or an automated test can run it. Prefer binary checks (pass/fail) over vague goals. Where possible include example test data and expected API responses or UI states.

If the contractor will deploy feature flags or staged rollouts, add tests keyed to the flag states and include rollback criteria. Legal and procurement guidance also recommends documenting who signs off on acceptance and how many revision rounds are allowed to avoid disputes.

Tell contractors exactly what telemetry events, user properties, and aggregation queries must exist before acceptance. Provide example analytics SQL (or whichever query language you use) that verifies active users, error counts, and conversion lift for the change. Contractors should implement instrumentation hooks and unit tests for event shape.

Also include rollout thresholds and rollback triggers. A typical minimum: events for success/failure, a user‑id or anonymous id, timestamps, and context fields (page, platform, experiment id). Adding the verification query to the PRD eliminates guesswork and prevents the common ‘we shipped but no one instrumented it’ failure mode.

Finish the mini‑PRD and hand it to the contractor with an explicit 48‑hour plan: 0–4h read + questions, 4–24h prototype/mocks & instrumentation, 24–40h implementation, 40–48h tests, demo, and sign‑off. This removes schedule ambiguity and gives both sides a predictable cadence.

Attach the acceptance tests and telemetry queries as checkboxes the contractor must close. If disputes or ambiguous items remain, require a single clarification call limited to 30 minutes — prefer written follow ups so onboarding context stays with the PRD for the next contractor.
