    • What is the relationship between the earliest start time (ES) and earliest finish time (EF) of an activity?

  • ES = EF - (estimated) duration of the activity

    Study Notes

    Project Management Terminology

    • AOA stands for Activity on Arrow, which represents a type of project network diagram.

    Project Network Components

    • Nodes or events represent the beginning or ending points of one or more activities in a project network.

    Activity Time Calculations

    • The earliest finish time (EF) of an activity is the sum of its earliest start time (ES) and duration.
    • The latest start time (LS) of an activity is determined by subtracting the duration from the latest finish time (LF).
    • The latest finish time (LF) of an activity is calculated by subtracting the slack from the earliest finish time (EF).

    Critical Path and Slack

    • The critical path is the sequence of activities that determines the minimum duration required to complete a project.
    • The slack of an activity is the difference between its latest finish time and earliest finish time.
    • The formula to calculate slack is LF - EF.

    Activity Characteristics

    • An activity is a specific task or job that must be completed in a project.
    • Activities have durations, earliest start times, and earliest finish times.

    PERT and CPM Methodologies

    • PERT (Program Evaluation and Review Technique) is a methodology used for projects where time required to complete activities is not known in advance.
    • CPM (Critical Path Method) is a methodology used for projects where time required to complete activities is known in advance.
    • The primary purpose of PERT and CPM is to identify the critical path and determine the minimum duration required to complete a project.
    • PERT charts or network diagrams are used to visualize the project network and identify relationships between activities.

    Key Differences

    • The primary difference between PERT and CPM is the uncertainty of activity durations.
