Scope
What it is
Scope is the agreed boundary of a project: what will be delivered and, just as important, what will not. It can be written as in-scope and out-of-scope lists covering processes, systems, users, locations and timeframes. Scope is agreed with the sponsor and reviewed whenever a change is requested, so everyone sees the effect on cost and time.
Why it matters
Without a boundary, projects grow quietly (scope creep) and miss their dates. A written scope gives you a calm way to say "that is a good idea, but it is outside what we agreed". Scope statements also protect the team's morale, because people can see exactly what they committed to and when it is finished.
Example
For the Marlow Online Store checkout project, in scope are the delivery-cost display and the order summary page. Out of scope are loyalty points, a new payment provider and the mobile app, which are listed as possible future phases. Each excluded item is written down on purpose, so the team can point to it when someone later asks why it was not included.
