Which are examples of processes that may be used once or at predefined points in the project life cycle?

Develop Project Charter occurs once at the very beginning of a project or phase to formally authorize it, and Close Project or Phase occurs once at the conclusion to formally complete and transfer the project or phase. Both are bounded to specific, predefined points in the project life cycle rather than being repeated throughout. PMBOK explicitly categorizes these as processes performed once or at predefined points, distinguishing them from iterative or ongoing processes.

Define Activities and Acquire Resources are iterative processes that may be repeated across phases or when scope changes, rather than being limited to predefined single points.

Control Schedule and Conduct Procurements are ongoing processes performed throughout the project execution and monitoring phases, not at single predefined points.

Monitor Communications and Control Costs are continuous monitoring processes performed throughout the project life cycle, not bounded to a single occurrence.
