During a project planning phase, the project manager realizes that project performance win be measured...

The project manager realizes that the project performance will be measured based on budget deviation and revenue, but without consideration for the overall project schedule. This could lead to a situation where the project is successful in terms of budget and revenue, but fails in terms of schedule. Therefore, the project manager should review the schedule baseline and consider adopting a schedule performance indicator. This will ensure that the project schedule is also taken into account when measuring project performance. References: PMBOK Guide, 6th Edition, Section 6.6.1.1, “Schedule Baseline” and Section 7.4.2.1, “Cost Performance Baseline”
