It happens every single time: we finalize our Project Planning documentation, get formal sign-offs, and within two weeks, stakeholder requests begin derailing our progress. How do we protect our agreed-upon baseline?

Preventing scope creep requires setting clear boundaries right when your Project Planning phase concludes. You must establish a strict "One-In, One-Out" policy for all post-baseline changes. If a stakeholder insists on adding an unplanned feature, they must identify an existing requirement of equal complexity to remove or delay. Additionally, ensure that the financial and timeline impacts of every change are made visible to executive sponsors immediately, which naturally deters unnecessary adjustments.
Do your project charters clearly define what is explicitly out of scope? Sometimes, simply listing the features or platforms you will not be building during this phase is enough to stop stakeholder assumptions from turning into scope creep.
We manage this by creating a dedicated product backlog for phase two. Every single new request made after the planning baseline is locked gets automatically routed there, keeping phase one completely protected.
Moving new items to a phase-two backlog is an excellent gatekeeping mechanism. As Theresa Albright noted, making the timeline impacts visible alongside this backlog keeps the core scope secure throughout the project lifecycle.
We usually focus only on what is included in the project plan. Not explicitly defining the out-of-scope boundaries leaves too much room for interpretation, which allows stakeholders to claim that their new requests were implied all along.
