  1. Chapter 8 Scheduling

  2. Objectives • Determining work breakdown structure (WBS) • Noting precedence relationships • Using scheduling tools

  3. Work Breakdown Structure (WBS) • Work breakdown structure: a schedule that shows each step of the project. • To develop a schedule a successful project manager must break the project down into smaller work components. • Hierarchy of work: A job must be broken down into objectives, then into tasks, and finally into activities (See fig 8-1, page 154). • Objectives: Big chunks of the project, when added together accomplish the project goal. • Tasks: are sub-objective, or work packages, each made up of multiple activities. • Specs: specifications of what must happen with a project. • Activities: the basic building blocks of a project, the individual actions that will be performed one at a time (fig 8-4, page 157). • Duration rule: rule that requires you to define activities that will take hours to days to complete, thereby limiting the amount of time during which you will have no visibility of progress.

  4. Precedence Relationships • Precedence relationships: relationships between activities based on when they occur in relation to each other. • 4 categories that will influence sequencing: • 1. Technical requirements: example – run electrical wiring prior to putting up drywall. • 2. Safety and efficiency: example – disconnect power before making repairs. • 3. Policy or preference: example – vendor certification prior to contract. • 4. Resources: money, computer equipment, technical expertise or anything that you may need to accomplish the goal. • The only way to cope with the unexpected is to have all the expected events planned for, and then you can add some elbow room to cope with the remaining unexpected problems.

  5. Scheduling Tools • Gantt chart: a bar chart that is a visual representation of the sequencing and duration of activities on any given project (fig 8-5, page 162). • PERT chart: diagrams, consisting of nodes connected by arrows, that show the flow of work and highlight precedence relationship. • Activity-on-Node chart: each activity is represented by a node or box (fig 8-7, page 164).

  6. Summary • Work breakdown structure: a schedule that shows each step of the project. • Hierarchy of work: A job must be broken down into objectives, then into tasks, and finally into activities. • Precedence relationships: relationships between activities based on when they occur in relation to each other. • The only way to cope with the unexpected is to have all the expected events planned for, and then you can add some elbow room to cope with the remaining unexpected problems. • Gantt chart: a bar chart that is a visual representation of the sequencing and duration of activities on any given project. • PERT chart: diagrams, consisting of nodes connected by arrows, that show the flow of work and highlight precedence relationship. • Activity-on-Node chart: each activity is represented by a node or box.
