Questions and Answers

What is the formula for calculating total float (TF)?

    Study Notes

    Project Management Formulas and Concepts

    • Total Float (TF) formula: Not provided in the original text, but it is typically calculated as TF = LF - EF, where LF is the latest finish time and EF is the earliest finish time.
    • Parkinson's Law: Refers to the idea that "work expands to fill the time available for its completion".

    Standard Deviation and Time Estimates

    • Standard Deviation (σ) formula using three time estimates (a, m, b): σ = (b - a) / 6
    • TE = $(a + 4m + b) / 6 represents a method to estimate the expected time for a task.

    Network Diagrams and Scheduling

    • AON Network: Primarily used to create a visual representation of a project schedule.
    • Gantt Chart: A type of bar chart that illustrates a project schedule. Advantage: provides a clear visual representation of the project timeline.
    • Disadvantage of Gantt Chart: Can be cumbersome to create and update manually.

    Critical Path and Float

    • Critical Path: Represents the sequence of activities that determines the minimum duration required to complete a project.
    • Slack (Float): Refers to the amount of time an activity can be delayed without affecting the overall project duration.

    Project Management Tools and Techniques

    • Precedence Diagramming Restrictions: Define the relationships between activities in a project.
    • PERT and CPM: Two popular project management techniques developed in the late 1950s.
    • CPM and PERT: Stand for Critical Path Method and Program Evaluation and Review Technique, respectively.
    • PERT was developed for the Polaris missile/submarine project in 1958.

    Project Management Fundamentals

    • A project: Comprises a series of connected activities and events.
    • Activity: A specific task or set of tasks that are required by the project, use up resources, and take time to complete.
    • Immediate Predecessor: The activity that must be completed before another activity can begin.
    • Network Scheduling: Advantage: allows for the creation of a realistic project schedule.
    • Henry L. Gantt: Developed the Gantt chart.
    • Basis for monitoring a project: The project schedule and budget.
    • Resource allocation: Can be planned using a Gantt chart, which shows when resources are needed.
