Practical guidance
Why define project scope before planning dates?
Scope describes the boundary of the work; a timeline describes its sequence. Agreeing on deliverables and acceptance criteria first gives you a better basis for estimating dates and prevents a plan from treating uncertain work as settled.
A useful project scope should include
- A measurable objective tied to the project need
- In-scope work and meaningful exclusions
- Deliverables with observable acceptance criteria
- Dependencies, assumptions, constraints, and risks kept distinct
