Question

If a project activity has an Early Start (ES) of 6 and a Duration of 10, then its Early Finish (EF) value will be 4.

a True.
b False

Answer 1

The claim that the Early Finish (EF) value will be 4 given an Early Start (ES) of 6 and a Duration of 10 is false. The correct Early Finish (EF) value is calculated as 15, not 4.

Step-by-step explanation:

The statement is false. In project management and schedule development, the Early Finish (EF) of an activity is calculated by taking the Early Start (ES) and adding the Duration of the activity to it, minus one day because the start date is included in the duration. Therefore, if the Early Start of an activity is 6 and its Duration is 10, we calculate the Early Finish as follows:

EF = ES + Duration - 1
EF = 6 + 10 - 1
EF = 15

Thus, the correct Early Finish for the project activity is 15, not 4.
