In Critical Path Method, the project completion period is the EF of last activities.

Changing the duration of a critical activity will not affect the overall completion time.

The starting activities that have no predecessor cannot be carried out in parallel.

Changing the duration of a non-critical activity will not affect the overall completion time, provided the revised float is positive.

The backward pass calculation cannot proceed if the forward pass had not completed.

The critical path activities can be identified only after all the floats were determined.

To start the backward pass computation, the LF is equal to EF for the last activity.

Organizing a trip to Paris for the upcoming school holiday is a project

Organizing a tour of multiple cities for Christmas holiday is an operation.

In Critical Path Method, the project completion period is the sum of all of all activities duration.

Develop an App for smartphone by hired programmer is a project

The LS and LF is the result of forward pass calculation.

LS = LF - t

Activities on critical path will have positive float.
