statement-of-work

name: statement-of-workdescription: "Write a tight Statement of Work (SOW) that prevents scope creep and payment disputes. Use when asked to write a SOW, a scope of work, a project agreement, or to formalise what was agreed after a proposal. Produces an SOW — scope (and explicit exclusions), deliverables with acceptance criteria, timeline & milestones, payment schedule, assumptions, change-control, and terms. The contract layer after the proposal sells."

Statement of Work Skill

The proposal wins the deal; the SOW protects it. Most consulting pain — scope creep, "that's not what I meant," late or withheld payment — traces to a vague SOW. This skill writes a precise one: exactly what's in (and explicitly out), how each deliverable is accepted, when money changes hands, and how changes are handled — so both sides are protected.

Required Inputs

Ask for these only if they aren't already provided:

• The engagement — parties, and what was agreed (often from a consulting-proposal).
• Deliverables — the concrete outputs and how "done" is judged.
• Timeline & dependencies — milestones, and what you need from the client and by when.
• Commercials — total fee, payment schedule/triggers, and rate for out-of-scope/change work.

Output Format

Statement of Work — [project]

Between: [provider] and [client] · Effective: [date]

1. Scope — what will be done, specifically. Then explicit exclusions ("Out of scope: …") — the most valuable section; unsaid scope is assumed-included by clients.

2. Deliverables & acceptance criteria — each deliverable with how it's accepted (the objective bar, and a review window — e.g. "approved, or feedback within 5 business days, else deemed accepted").

3. Timeline & milestones — phases, dates, and client dependencies (their inputs/approvals — and what happens to the timeline if they slip).

4. Payment schedule — amounts tied to milestones/dates, invoicing terms, and late-payment terms. Deposit up front where appropriate.

5. Assumptions — what the plan and price depend on (access, environments, responsiveness) — so a broken assumption is a change, not a fight.

6. Change control — how scope changes are requested, priced (the change rate), and approved in writing before work proceeds. This is the anti-scope-creep clause.

7. Terms — IP/ownership (on payment), confidentiality, termination, liability — flag that legal should review for material engagements.

Quality Checks

• Scope includes an explicit "out of scope / exclusions" list
• Every deliverable has objective acceptance criteria and a review/sign-off window
• Payment is tied to milestones/dates with late terms (and a deposit where apt)
• Client dependencies are listed, with the timeline consequence if they slip
• A written change-control process with a change rate is defined
• Assumptions the price depends on are stated

Anti-Patterns

• Do not leave scope open-ended — without exclusions, clients reasonably assume everything is included
• Do not omit acceptance criteria — "deliver a website" with no bar means endless revisions
• Do not skip change control — it's the clause that turns scope creep into billable change requests
• Do not ignore client dependencies — if their delay silently becomes your problem, you eat the cost
• Do not present this as final legal advice — recommend counsel review for significant contracts

Based On

Statement-of-work / contracting practice — explicit scope + exclusions, acceptance criteria, milestone payments, change control.
