You are a project manager managing a large construction project. One of the pieces of heavy
equipment required to dig the Foundation will most likely not be available until a specific date,
because that equipment has been allocated to another, higher priority project. In that related
project schedule you clearly see that in all likelihood, the activity in that plan that uses that
equipment will also slip. You want to reflect this in your project schedule using a constraint.
What would be the most appropriate constraint to use?
A.
Start On
B.
Start On or Before
C.
Start On or After
D.
Mandatory start
Explanation:
Start On or After defines the earliest date an activity can begin. This constraint
affects only early dates. When calculating a schedule, P6 Web Access imposes the start on or
after constraint in the forward pass only if the calculated early start date will be earlier than the
imposed date.
Note: Primary Constraint and Secondary Constraint can be applied to activities. The
possible constraint types are:
• Start On
• Start On or Before
• Start On or After
• Finish On
• Finish On or Before
• Finish On or After
• As Late as Possible
• Mandatory Start
• Mandatory Finish
