A project manager is working on a large, complex project. While creating the project schedule, the project manager defines key points at which progress to date can be identified. Which of the…

Approval gates are formal go/no-go decision points typically used at phase boundaries, not general progress-tracking checkpoints distributed throughout a schedule.

Milestone development involves establishing specific, significant events or checkpoints within the project schedule that have zero duration and serve as measurable progress indicators. These markers allow the project manager and stakeholders to assess schedule performance at defined intervals throughout the project. Milestones are a formal output of the schedule planning process and are distinct from activities because they represent a moment in time, not work being performed.

Critical path identification determines the longest sequence of dependent tasks defining the minimum project duration, which is a separate scheduling technique unrelated to marking progress points.

Quality gates are review checkpoints used to verify that defined quality standards have been satisfied, not to track general schedule progress.
