Scope of work
The specific work included in an engagement - the deliverables, boundaries and exclusions. A clear scope is the main defence against scope creep.
For example, a marketing agency's scope for a campaign states that it will produce three ad creatives, one landing page and a two-week optimisation window - and explicitly excludes video production and ongoing management. When the client later asks for a promo video, everyone can see at a glance that it falls outside the agreed scope.
Why it matters to your firm: scope is where margin is won or lost. A precise, written scope with clear exclusions keeps projects profitable, gives your team firm boundaries, and turns awkward 'that's extra' conversations into a simple, pre-agreed change order.
- Describing deliverables but not exclusions.
- No acceptance criteria, so 'done' stays subjective.
- Letting the scope live in email instead of the contract.
