Use the following order of heuristics: 1. Minimum slack, 2. Smallest duration, 3. Lowest identification number Schedule resource load chart with ES and slack updates Note: Recall, in the schedule resource load chart the time-constrained scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project. "TP" stands for time period. How long will the project take if it was NOT resource-constrained?.
