Read the first 7 Project Scheduling & Critical Path flashcards as text

  1. A project has activities A→C→E on one path (durations 3,5,4) and A→B→D→E on another (durations 3,2,6,4). Which path is critical?

    Answer: A→B→D→E with duration 15

    A→B→D→E totals 3+2+6+4=15 days, which is longer than A→C→E at 3+5+4=12 days, making it the critical path.

  2. What does a negative float (slack) value on an activity indicate?

    Answer: The schedule has a constraint violation or the project is behind schedule

    Negative float means the activity's late finish is earlier than its early finish, indicating a schedule constraint violation or delay.

  3. Which scheduling technique uses three time estimates (optimistic, pessimistic, most likely) to calculate expected activity durations?

    Answer: Program Evaluation and Review Technique (PERT)

    PERT uses three-point estimates with the formula (O + 4M + P) / 6 to calculate expected duration under uncertainty.

  4. In a Precedence Diagramming Method (PDM) network, which relationship type means successor cannot start until predecessor finishes?

    Answer: Finish-to-Start (FS)

    Finish-to-Start (FS) is the most common dependency type, where the successor activity cannot begin until the predecessor is complete.

  5. A project manager applies fast tracking to compress the schedule. What is a primary risk of this technique?

    Answer: Rework because activities that were meant to be sequential now overlap

    Fast tracking overlaps activities that were originally planned sequentially, which can cause rework if later work depends on outputs from earlier work that isn't complete.

  6. The Schedule Performance Index (SPI) for a project is 0.85. What does this indicate?

    Answer: The project is performing at 85% of the planned rate of progress

    An SPI of 0.85 means the project is only accomplishing 85 cents of work for every dollar of scheduled work, indicating it is behind schedule.

  7. Which output of the Develop Schedule process shows planned start and finish dates for project activities?

    Answer: Project schedule baseline

    The project schedule baseline is the approved version of the schedule model, showing planned start and finish dates used to measure schedule performance.
