Given the precedence diagram and activity duration in the Excel template, determine ES, EF, LS, LF and slack in each activity, identify the critical path, and identify the expected duration of the project. Formula: Slack time = LS-ES or LF-EF. Figure Sense: What information do I know? What is the algorithm for doing the tasks mentioned? How do you solve this problem in the Excel template? 5 6 Activity Duration ES EF LS LF Slack 1-2 4 2-7 6 1-5 9 5-6 5 2-6 2 6-7 3 Critical Path Project Expected Duration 7 LS LF ES EF
