Answer the questions based on the partially completed network diagram of a project below where the five values in each square grid represent the task time (center), ES (bottom left), EF (bottom right), LS (top left), and LF (top right) times. This problem asks you to find the values of those cells marked by "ES", "LS", or "LF" in red. You do not need to obtain the values for the cells marked by "xx" or "yy". 0 0 6 A 6 6 10 6 6 yy 6 7 yy LF 9 B 8 D 17 13 15 LF 14 Forward pass to determine ES and EF: (1) What is the Earlest Start (ES) time for activity E? (2) What is the Earlest Start (ES) time for activity G? Backward pass to determine LF and LS: (3) What is the Latest Start (LS) time for activity E? (4) What is the Latest Finish (LF) time for activity C? (5) What is the Latest Finish (LF) time for activity D? LS ES 6 15 E 15 23 co 8 F 16 ES XX yy 7 G 23 23 XX 23 23 H 4 27 27 Overall: You can complete the ES, EF, LF, LS to answer the following question or manually inspect the network to find the answer. (6) What is the critical path? |(Click to select)
