Examine the figure given below:

You are the project manager of this project. Tom, a project team member, reports that Activity D
will be delayed by 12 days due to the unavailability of the resources from the vendor. What will this
delay do to your project completion, if you allow the delay to enter into the project?

A.
The project will be one day late.

B.
The float for activity D will be consumed.

C.
The project can still finish on time.

D.
The project will be seven days late.

Explanation:
The project will be just one day late due to this delay. The path ADGJ takes a total of 15 days. If
Activity D takes a total of 13 days (i.e. 12 + 1), then the path will now take 27 days to complete.
This causes the critical path to shift to ADGJ and the project will end on day 27 rather than day 26.
Answer options D, B, and C are incorrect. These are not the valid answers, as the project will now
take 27 days to complete, rather than 26.
