Assume that the catering manager was able to estimate the number of hours needed to complete each activity as follows. Activity J K L M N O P Q a. b. C. d. e. Immediate Predecessor(s) Start Start J K,M K,M L,N P,O Pessimistic time 16 10 10 3 9 10 10 15 Most Likely time (Probable) 11 7 6 3 5 7 8 10 Optimistic time 6 5 5 3 2 4 5 7 Expected duration (te) Variance Draw the network diagram of project activities (i.e. activity duration is the calculated to) Which path is the critical path? What is the length of the whole project? Calculate the ES, EF, LS, LF and Float/Slack for all activities Which activity has the highest uncertainty/variation in its estimations?
