Study Notes

Work Breakdown Structure (WBS)

  • A project management tool that takes a step-by-step approach to complete large projects with several moving parts.
  • Breaks down the project into smaller components, integrating scope, cost, and deliverables into a single tool.

WBS vs. Programme

  • WBS: Comprehensive classification of project scope, containing no activity duration, no resource assignments, and no dependencies.
  • Programme: Actual work to be done (only the activities on the last level of the WBS), containing activity durations, resource assignments, and dependencies.

Why Use WBS?

  • Estimate the cost of a project.
  • Establish dependencies.
  • Determine a project timeline and develop a schedule.
  • Write a statement of work (SOW).
  • Assign responsibilities and clarify roles.
  • Track the progress of a project.
  • Identify risk.

When to Create a WBS?

  • The first step in developing a project schedule.
  • Defines all the work that needs to be completed (and in what order) to achieve the project goals and objectives.

How Does WBS Fit into Programming?

  • Record the overarching objective.
  • Divide the overarching objective into smaller and smaller pieces, but stop before listing out every action that must be taken.
  • Focus on concrete deliverables rather than actions.

Tips for Making a WBS

  • The 100% rule: The work represented by the WBS must include 100% of the work necessary to complete the overarching goal without including any extraneous or unrelated work.
  • Three levels: A WBS should include about three levels of detail.
  • Mutually exclusive: Do not include a sub-task twice or account for any amount of work twice.
  • Make assignments: Every work package should be assigned to a specific team or individual.
  • Outcomes, not actions: Focus on deliverables and outcomes rather than actions.

Examples of WBS Frameworks

  • Definition of Elements (Rawlinsons): A framework for building construction projects, including structure, site preparation, substructure, frame, structural walls, upper floors, exterior fabric, and more.
  • Masterspec CBI (Co-ordinated Building Information) classification system: A framework for building construction projects.

Activity: Creating a WBS for a House

  • Familiarise yourself with the plans provided.
  • Use the Rawlinsons Elemental Breakdown as the framework.
  • Obey the rules of WBS.
  • Use appropriate item numbering.
  • Arrive at the level where you have clear tasks.
  • Be project specific.

WBS and Programme Distinction

  • Work Breakdown Structure (WBS) is a comprehensive classification of project scope, whereas a programme is actual work to be done, with activity durations, resource assignments, and dependencies.

What is a WBS?

  • A WBS is a project management tool that breaks down a large project into smaller components to integrate scope, cost, and deliverables.
  • It takes a step-by-step approach to complete large projects with several moving pieces.

Why do we use WBS?

  • To estimate the cost of a project
  • To establish dependencies
  • To determine a project timeline and develop a schedule
  • To write a statement of work (SOW)
  • To assign responsibilities and clarify roles
  • To track the progress of a project
  • To identify risk

When do we create a WBS?

  • As the first step in developing a project schedule
  • To define all the work that needs to be completed to achieve project goals and objectives

How does WBS fit into programming?

  • Record the overarching objective to be accomplished
  • Divide the objective into smaller and smaller pieces, focusing on concrete deliverables rather than actions

Tips for making a WBS

  • Follow the 100% rule: the WBS must include 100% of the work necessary to complete the overarching goal
  • Ensure child tasks on any level account for all the work necessary to complete the parent task
  • Use three levels of detail
  • Make assignments: every work package should be assigned to a specific team or individual
  • Focus on outcomes, not actions: remember to focus on deliverables and outcomes rather than actions

Examples of WBS

  • Definition of Elements (Rawlinsons) framework: uses categories like Structure, Site Preparation, Substructure, Frame, and more
  • Masterspec CBI (Co-ordinated Building Information) classification system
  • Examples of WBS format: notice how the rules of building a WBS are applied in the example, with a maximum of three levels, allocation of effort across all work packages, and no duplication of work.
