Query related to Lag
Please help me explain the following:
In PMBOK Ver 5 Page 158 , there is following example:-
Activity Write Draft --> SS - 15 Days (Lag) --> Activity Edit Draft.
It mentions that Activity Edit Draft will start 15 days AFTER the Activity Write Draft.
This shown by Start to Start Relationship with 15 days lag.
1) If it is Start to Start Relationship with 15 days lag, then why we are not mentioning the relationship as SS + 15 Days (Lag)?
2) Why we are NOT using the Plus Sign (+) like SS + 15 Days (Lag)
