Solution Requirements

Utilize Microsoft Excel and$/$or Word to complete the following steps:

$1.$ Draw the project network diagram.

$2.$ Find the critical path. Utilize a forward and backward pass analysis. Create a table to display ES$,$ EF$,$ LS$,$ LF$,$ and slack. Calculate the expected project completion time and the standard deviation of the critical path. Use the mean activity time in your calculations.

$3.$ Find the probability of completing in $270$ days.

$4.$ Examine the possibility of crashing the project to $250$ and $240$ days, respectively, to answer the third discussion question. Clarification: use the optimistic time as the crash time $$ you will need to calculate the total cost of crashing using the cost per day. You do not need to calculate cost per day for crashing as with some problems $$ the cost is per day to crash the project down to the optimistic time.

$5.$ Provide recommendations to managers of actions that should be pursued. Share your own insights that you discovered while solving the problem.
