    Study Notes

    PMGT3623 Scheduling

    • The course covers scheduling, course resources, and assessment components
    • Week 2 focuses on defining and sequencing project tasks
    • Week 2 topics include: defining tasks and milestones, sequencing tasks, finish-to-start, start-to-start, start-to-finish, finish-to-finish, external vs internal dependencies, mandatory vs discretionary dependencies, and lead/lag time estimations
    • A Work Breakdown Structure (WBS) is a deliverable-oriented grouping of project elements, organizing and defining the total scope of the project
    • Each descending level of a WBS represents an increasingly detailed definition of the project work
    • Milestones are specific moments with a definitive deliverable, while tasks are the efforts needed to reach those milestones
    • Tasks are broken down into smaller components (work packages) to manage the overall project scope
    • Tasks include details like objectives, deliverables, resources
    • Defining milestones involves identifying critical points in the project timeline signifying the completion of major deliverables or phases
    • Defining milestone criteria specifies what must be achieved for the milestone to be considered complete
    • This helps to monitor progress and ensure alignment with project goals
    • Examples of 'define task and milestone' include designing, manufacturing, and marketing a palm book computer, as well as building a garage.
    • Sequencing in project management is arranging project tasks in a specific order. It involves organizing and prioritizing tasks logically to ensure smooth execution and successful completion
    • This is vital for meeting deadlines and achieving project goals efficiently
    • Visualization tools like network diagrams are used to demonstrate task order and dependencies
    • Logical dependencies between tasks include Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF) and Start-to-Finish (SF)
    • External dependencies relate to tasks in different projects, requiring approvals from external parties
    • Internal dependencies concern tasks within the same project
    • Mandatory dependencies are required by contract, law, or best practices, while discretionary dependencies could lead to financial benefits
    • Project risk increases with the number of external task dependencies affecting project completion time and cost
    • Discretionary dependencies can impact project duration as decisions are made during the project

    Task Dependency and Project Risk

    • A diagram illustrates the relationship between task dependencies and project risk, showing increasing risk with more mandatory dependencies and external dependencies
    • External dependencies increase inherent risk more than discretionary dependencies

    Estimate Task Duration (Discrete Approach) – Part C

    • Two primary steps for estimating task duration:
      • Historical Data Analysis: Review historical data from similar tasks or projects to estimate the duration of the current task
      • Expert Judgment: Use experts with experience in similar projects to refine/adjust estimates if historical data is not available

    Estimation Techniques

    • Analogous Estimation: Assumes the current project will cost the same as a similar past project, adjusting for differences in scope, complexity
    • Parametric Estimation: Uses statistical relationships between historical data and variables like the number of units produced per hour
      • Example: If producing 10 units takes 2 hours, producing 20 units will take 4 hours
    • Three-Point Estimation: Uses three estimates to derive an average duration or cost for an activity
      • Example formula: Expected value = (0 + 4M + P) / 6

    Review Questions

    • Define project tasks and milestones
      • Project tasks are the individual work efforts to achieve a project goal while milestones are major events that mark significant progress and completion of phases.
    • What are lead and lag times? How are they related to project scheduling?
      • Lead time is the time a dependent activity starts before its predecessor is finished, used for Finish-to-Start (FS) dependencies to reduce scheduling time. Lag time is the idle wait time between activities and is added to overall time, used for all types of dependencies.
    • What are the differences between discretionary and mandatory dependencies? What are the four different types of logical dependencies between two tasks?
      • Mandatory dependencies are required by contract, law, or best practices, whereas discretionary dependencies are optional and can lead to benefits. The four logical dependencies are FS, SS, FF, and SF.
    • What are the steps in estimating the duration of a task?
      • This includes reviewing historical data from similar projects and using expert judgment for unavailable historical data.
    • What is the impact of having too many external task dependencies on project risk?
      • Having too many external task dependencies increases project risk in terms of project completion time/cost. External dependencies are often less controllable than internal/discretionary dependencies.
    • Does the discretionary dependency impact project duration?
      • Discretionary dependency can impact project duration. It may lead to projects taking more or less time than projected with potential cost implications.
