Your firm is implementing a balanced scorecard. As the project manager, you need to make sure the project is completed on time and on-budget. The table below lists the steps that need to be complete. The data analysis team members are going to be late delivering some key data points that are needed to complete the project (activity B). How many weeks can this activity be delayed without delaying the completion of the project?

Answer 1

Answer:

Activity	Duration, D	Early start, ES=Max of early finish of preceding activities	Early finish, EF = ES + D	Late finish, LF= Min of LS of successor activities	Late start, LS= LF - D	Total slack= LF-EF
A	12	0	12	12	0	0
B	5	0	5	9	4	4
C	7	12	19	19	12	0
D	2	19	21	21	19	0
E	8	5	13	17	9	4
F	9	13	22	26	17	4
G	5	21	26	26	21	0
H	8	26	34	34	26	0
