Slack

A measure of the flexibility in scheduling activities; it represents the amount of time that a task in a project can be delayed without causing a delay to subsequent tasks or the project completion date.

PERT

Stands for "Program Evaluation and Review Technique," a project management tool used to schedule, organize, and coordinate tasks within a project.

CPM

Critical Path Method, a project management tool used to schedule, organize, and coordinate tasks within a project. It identifies the longest stretch of dependent tasks and measures the time required to complete them from start to finish.

Activity Durations

The length of time taken to complete specific activities within a project or process, crucial for project planning and scheduling.
