Project phase gates are a powerful tool, but they’re easy to brush past. When used correctly, they create natural opportunities to verify that a project is on the right track, that the right people are aligned, and that the investment is still worth making.
The practices below are about getting the most out of those opportunities.
Before a project moves past scoping, take time to establish a defined list of what each phase is expected to produce and what "done" looks like. Include relevant business leaders in the conversation to keep everyone on the same page. Think about what resources will be required and plan accordingly.
This upfront investment pays off throughout the project. When deliverables and requirements are planned from the beginning, there's less ambiguity and rework down the line. When something new comes up mid-project (a new deliverable, for example) you'll be equipped to ask the right question: is this genuinely value-added?
Example: Suppose a company is replacing written work orders with a mobile app for field technicians.
The team agrees upfront that Phase 1 delivers a working mobile app connected to the existing work order system. When HR later requests an in-app certification tracker, it's an easy call: it wasn't in the original plan and it’s not an immediate need, so it can wait.
A well-designed project plan has room to breathe. Yet not all flexibility is the same.
For minor adjustments (small timing shifts, clarifications, low-impact changes), build flexibility directly into the plan. These things will happen on any real project. Smaller changes can typically be absorbed quickly.
For significant scope changes (major new requirements, shifts in business direction, resource constraints that affect the timeline), treat these as project-level decisions that require a formal response. The timeline and budget will extend. The right decision makers must be brought in to decide if the change adds value or if it should be deferred.
A gate review that happens after a major scope change is a natural moment to reset: here's where we are, here's what changed, here's what the project looks like now. That transparency keeps stakeholders informed and keeps accountability intact.
Example: Small delays like late device shipments are expected and planned for. When Operations decides mid-project to triple the pilot size, leadership is brought in to approve the new timeline and cost before anything changes.
Even with a plan from the start, changes can still creep in. Create a clear, agreed-upon path for evaluating, approving, and communicating changes mid-project so the team knows how to handle it efficiently. Something that made sense six months ago might not make sense today, and it’s important to prepare to manage changes efficiently and thoroughly.
When a big change comes in, fully account for the dependencies it creates. Projects that span multiple areas of a business are vulnerable here. Map the dependencies explicitly before approving the change.
Change control also creates a useful record. When a project extends in timeline or budget, the reasoning is documented. Decision-makers can see what choices were made and make improvements for future projects.
Example: When the GIS team requests live map integration, the team walks through everything it would affect before agreeing to anything. They decide to push it to Phase 2. When the project finishes two weeks late, there's a clear record of why, and it's obvious the decision saved more time than it cost.
It sounds counterintuitive, but taking time to complete each phase properly allows projects to move faster. When gate criteria are met, the right signoffs are in place, and business leads have engaged with what they're approving, the project can move into the next phase smoothly.
Establish clear criteria for moving from one phase to the next. The goal is for each gate to feel like a smooth transition and to avoid going back to reopen previous stage gates. Projects that span multiple areas of a business benefit enormously from honest, thorough timeline planning.
Example: Before rolling out to all technicians, the team requires 30 days of clean data from the pilot group. During that window, a connectivity issue is caught and fixed that would have caused problems across most field routes.
Treat reviews as genuine decision points. Are the deliverables complete? Are the risks understood and manageable? Is the business case still valid? Have the right people weighed in? If a review can’t answer these questions, redesign it.
When phase gates are just a formality, value is lost. Teams go through the motions, and stakeholders stop engaging when they learn stage gates don’t actually change anything. Keep checkpoints focused on the questions that matter and they’ll be much more meaningful.
And be willing to evolve the process. If a particular gate consistently produces rubber-stamp approvals with little real discussion, that's useful information. It might mean criteria need to be sharpened, the right stakeholders aren't in the room, or the gate is positioned at the wrong point in the project lifecycle. The gate structure itself can be refined if needed.
Example: At the final review, Operations shares that overtime costs dropped during the pilot, giving leadership a reason to confident moving forward. After the project, the team realizes early reviews were easy to pass and tightens the criteria for next time.
Structured checkpoints help organizations stay intentional about what they’re building and why. Without gates, projects run on momentum alone. Money is spent and teams stay busy without explicitly questioning if the right things are getting done… or if the project is even still worth continuing. Organizations are limited by budgets, technical capacity, and people. Gates ensure these resources are continuously re-evaluated against current business priorities.
