A scheduler needs to represent a phase gate review that must occur after all phase activities finish. Which approach is best?
Answer: Insert a milestone with Finish-to-Start links from all phase-closing activities
A gate milestone with FS relationships from all phase-closing activities correctly captures the dependency that all work must finish before the gate can be passed.
Which lag type applied to a milestone predecessor relationship would delay a milestone by 2 weeks after its predecessor finishes?
Answer: Positive lag of 2 weeks on a Finish-to-Start link
A positive lag on an FS relationship delays the successor milestone's earliest start by the specified duration after the predecessor finishes.
When baselining a schedule, what happens to milestone dates?
Answer: Milestone early and late dates are frozen as baseline start and finish targets
At baseline, milestone early and late dates are captured as BL Start and BL Finish, providing the reference against which schedule performance is later measured.
A project schedule has a 'Start No Later Than' (SNLT) constraint on an early activity. The network logic pushes that activity to start earlier than the SNLT date. What is the scheduling effect?
Answer: The activity gains positive float equal to the difference between logic date and SNLT date
SNLT acts as a ceiling on the late start; when logic places the activity earlier, the gap between the logic date and SNLT creates positive float.
Which scheduling concept specifically uses milestones as weighted events to measure physical percent complete in government contracts?
Answer: Milestone Weighted Method (MWM)
The Milestone Weighted Method assigns weights to milestones and uses their completion status to calculate earned value and physical percent complete.
A scheduler notices a milestone is missing from the integrated master schedule (IMS) that was listed in the contract's Contract Data Requirements List (CDRL). What is the FIRST corrective action?
Answer: Add the missing milestone with appropriate logic and constraints
Contract-required milestones must be reflected in the IMS; the first step is to add the milestone with proper logic so the schedule aligns with contractual obligations.
In a resource-loaded schedule, why is it important that milestones carry zero resource assignments?
Answer: Milestones with resources inflate the cost baseline artificially
Since milestones have zero duration, assigning resources to them creates fictitious cost loading that distorts the resource-loaded baseline and EVM calculations.
