Resource-Constrained Scheduling A project manager might estimate that the workforce situation constrains the project to using no more than 100 labor-hours or man-hours. However, the manager may have some choices in the matter. Specifying one union-constrained worker, working eight hours a day, five days a week, will result in a completely different activity estimate than two nonunion workers working 10 hours a day, seven days a week. That’s simple math. Extend this thinking to all activities and their precedence relationships. You will find resource constraints produce such things as completely different schedules, critical paths, and dependencies. The key point in resource-constrained scheduling is that time is not the independent variable. It is the dependent variable in the estimating equation. You do not specify time; you specify resource constraints, and this mathematically results in a calculation of time.
