Quiz Q2: Calculation of EAC (Example A)

A project has a BAC of 2000 and customer is concerned about schedule also. At a certain point in time (i.e. data date), the PV = 1000, AC = 1300 and EV = 1100. The cost escalation happened due to less productivity and the same is likely to continue in future also.

What is the EAC?

a) 2200

b) 2267

Start to Finish Relationship Explanation

SF as per PMBOK5 SF as per Lalit

As per PMBOK5 the definition of Start to Finish Relationship is: A logical relationship in which a successor activity cannot finish until a predecessor activity has started.

The same has been shown in the link  “SF as per PMBOK5” above.

However a better interpretation of this relationship will be as follows: A logical relationship in which the predecessor (although it may be happening later in time) DECIDES or DICTATES the finishing of the successor activity.

The same as been shown in link “SF as per Lalit” above.

Ans of Quiz Q1:

In layman’s language, predecessor means some thing which happens earlier. But in project management terminology, predecessor means the primary activity and successor means the dependent activity. Therefore the event A “Boss Going to Office” is the predecessor and event B “Driver making the car ready” is successor event.

As the process of making the car ready must be over by the time the boss starts for office with a buffer of 15 minutes, the best relationship to link them will be SF (Start to Finish relationship) with a lead of 15 minutes.

PMP Quiz Q1:

Activity A is, “Boss Going to office typically at 9 AM every morning”. Activity B is “Driver making the car ready 15 minutes BEFORE departure of boss”. Which is the predecessor activity here. Out of FS, SS, FF and SF, which is the best relationship to link these 2 activities?
