Question 1

What happens if work falls outside the scope?

Accepted Answer

That's where a change order process comes in. The SOW should include a procedure for handling out-of-scope requests: client submits a request, provider estimates additional time and cost, both parties agree in writing before work begins. Without this process, you'll either do free work or have an unhappy client.

Question 2

How detailed should a scope of work be?

Accepted Answer

Detailed enough that a stranger could read it and know exactly what's expected. Include: specific deliverables, quantities, quality standards, tools/technologies used, revision limits, acceptance criteria, timeline, and what's explicitly excluded. If you're debating whether to include a detail, include it.

Question 3

Who writes the scope of work?

Accepted Answer

Usually the service provider, based on the client's requirements. This is actually advantageous — the provider knows what's realistic and can define terms clearly. The client reviews, negotiates, and approves. Both parties sign. Never start work on a SOW that only one party has agreed to.

Question 4

Can the scope of work change after signing?

Accepted Answer

Yes, through formal change orders. A change order documents the new scope, revised timeline, and adjusted pricing. Both parties sign the change order, which becomes an addendum to the original contract. Verbal scope changes are a recipe for disputes — always put changes in writing.

Question 5

What's the difference between a SOW and a contract?

Accepted Answer

A SOW describes the work. A contract covers everything else — payment terms, IP ownership, liability, termination, dispute resolution. Many contracts include the SOW as an exhibit or attachment. The SOW is the 'what'; the contract is the 'how, when, and what if.' You need both.

Question 6

How do I prevent scope creep?

Accepted Answer

Three things: a detailed SOW that lists exclusions, a written change order process with cost implications, and the discipline to use it. When a client asks for something outside scope, don't say 'sure, I'll squeeze it in.' Say 'I can do that — here's a change order with the additional cost and timeline.' Scope creep dies when it has a price tag.
