    Study Notes

    Scheduling Issues

    • Scheduling issues can arise due to resources not being ready when needed, causing scope changes (creep).
    • Priorities may keep changing, potentially due to poor management, and individuals working on multiple projects can lead to productivity issues.

    Constructing Arrow Diagrams

    • Schedule at a level that can be managed, and avoid planning more detail than can be managed.
    • No task should have a duration greater than 4-6 weeks to prevent back-end loading.
    • Start with the beginning of the project and work towards the end, deciding what can be done first.
    • Diagram out what is logically possible, then deal with resource limitations, and schedule as if help is possible on the project.
    • Keep all times in the same increments (hours).

    Producing a Workable Schedule

    • Scheduling means trying to fit work between two fixed points in time.
    • Resource allocation is necessary to determine what kind of schedule is achievable.
    • Determine the critical path and available latitude for non-critical work.

    Simple Network Rules

    • A task can begin only after all preceding tasks are completed.
    • Arrows denote logical precedence.

    Scheduling Codes

    • ES: Early Start
    • LS: Late Start
    • EF: Early Finish
    • LF: Late Finish
    • DU: Duration

    Forward-pass Computations

    • Begin by determining the ES for all tasks in the project.
    • The latest EF for preceding tasks becomes the ES for subsequent tasks.

    Backward-pass Computations

    • Determine the latest start and latest finish times for each task in the project.
    • Decide how late the project can finish.

    The Float

    • A task has float if its ES/LS or EF/LF differ, meaning a time lag that is not critical.

    Critical Path and Float

    • Critical path tasks have no float, and the manager's attention must be applied to these tasks.
    • Effort may need to be adjusted, such as adding more people to the project or working overtime.

    Issues with Maintaining Critical Path

    • Not always possible to work overtime or add extra people to the project.

    Gantt Charts

    • A bar chart designed by Henry Gantt, simple to construct and read.
    • Best tool for communicating time frames to team members.

    Arrow Diagram Charts (Networks)

    • Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) both determine the critical path.
    • PERT calculates probability a task will be done by a certain time, while CPM doesn't.

    Program Evaluation and Review Technique (PERT)

    • A model for project management designed to analyze and represent tasks involved in completing a project.
    • Incorporates uncertainty, making it possible to schedule a project while not knowing details and durations of all activities.
    • Is an event-oriented technique, used more in R&D-type projects where time is the major factor.
    • An event in scheduling terminology is a specific point in time when something has just started or just finished.

    Milestone Events

    • An event representing a point in a project of special significance, usually the completion of a major phase of work.
