Question

A project has three paths through its network diagram: paths ABE, ACE, and ADE. Activity A will take two days. Activity B will take two days. Activity C will take three days. Activity D will take four days. Activity E will take two days. What will happen if activity C is delayed by three days?

a) The critical path will not change.

b) The critical path will change from path ABE to path ACE.

c) The critical path will change from path ACE to path ABE.

d) The critical path will change from path ADE to path ACE.

Explanation / Answer

Currently the crtical path is ADE as it takes highest time of 8 days

When C gets delayed by three days, time taken would be more by ACE which would be 10 days.

Therefore,

(d) The critical path will change from path ADE to path ACE.
