Read the first 7 Milestone & Constraint Management flashcards as text

  1. A milestone representing 'System Integration Complete' has no successors in the schedule. What scheduling problem does this represent?

    Answer: Dangling finish

    A milestone or activity with no successors creates a dangling finish, which violates sound CPM scheduling practice.

  2. Which constraint should be used when a task can begin no earlier than the receipt of a government permit expected on a fixed date?

    Answer: Start No Earlier Than (SNET)

    SNET is a soft constraint that prevents a task from starting before a specified date, appropriate for externally-driven early boundaries.

  3. In Earned Value Management, which milestone-related metric measures schedule efficiency at a point in time?

    Answer: Schedule Performance Index (SPI)

    SPI (EV/PV) measures how efficiently the project is progressing against the planned schedule, including milestone achievement.

  4. A scheduler is told a client milestone cannot move. After network analysis, the milestone shows -10 days of float. What is the BEST corrective action?

    Answer: Add resources or overlap tasks to recover 10 days on the driving path

    The correct response to negative float on a hard-date milestone is to compress the driving path through crashing, fast-tracking, or added resources.

  5. Which term describes a milestone that is linked to payment authorization upon verified completion?

    Answer: Contract milestone

    A contract milestone triggers a financial event such as payment or billing upon verified achievement, making it legally and commercially significant.

  6. During a schedule health check, an analyst finds a milestone with both a predecessor and a successor but its Total Float differs from all surrounding tasks. What is the most likely cause?

    Answer: The milestone has an applied date constraint creating a separate float path

    A date constraint on a milestone creates an independent float reference, causing its float to differ from tasks driven purely by logic.

  7. What is the recommended maximum percentage of activities that should carry hard constraints in a DCMA-compliant schedule?

    Answer: 5%

    DCMA guidance recommends that hard constraints should not exceed 5% of all activities to preserve the integrity of CPM calculations.
