Setting Boundaries and Assumptions

When documenting project scope, it is essential to set clear boundaries and record key assumptions. Boundaries define what is included and excluded from the project. They act as a fence, preventing scope creep by making it clear to all stakeholders what you will and will not deliver. For example, in a marketing campaign, a boundary might specify that only digital channels are included, while print advertising is not.

Assumptions are conditions you accept as true for planning purposes, even though you cannot guarantee them. They fill in gaps where information is incomplete or uncertain. For instance, you might assume that a new product will be available for the campaign launch, or that the client will provide all necessary branding materials by a certain date. Documenting assumptions helps everyone understand the basis for your scope, and what could cause changes if those assumptions turn out to be incorrect.

The boundaries and assumptions in the example above serve as a contract between you and your stakeholders. By stating exactly which marketing channels are in scope, you avoid misunderstandings about deliverables. If a stakeholder later requests print ads or an in-person event, you can refer back to the documented boundaries. Listing assumptions clarifies the conditions your plan depends on. If, for example, the product launch is delayed, everyone can see that this was a key assumption and will understand why timelines must change. This transparency helps manage expectations and reduces conflict, as everyone knows what was agreed upon from the start.
