  1. The A to Z of the Work Breakdown Structures By Nader Khorrami Rad, PMP ver 1.0

  2. Part 1Introduction

  3. 1.1.How We Manage Things

  4. 1.2.Grouping the Project Work

  5. 1.3.Why Should We Base the WBS on Products?

  6. Grouping / organizing project work based on its products or results is called:Work Breakdown Structure(WBS)

  7. The elements of the final product or result of a project, which is the output of the activities is called:DeliverableAll deliverables together = final product

  8. The sixth core principle of the PRINCE2:Focus on ProductsA successful project is output-oriented not activity-oriented.

  9. The most important aspect of focusing on products:Work is subject to strategies and usually change, but deliverables do not change as often.

  13. 1.4.From a Simple Grouping to a Hierarchy

  14. When we are dealing with large number of items, a simple one-level grouping would not be enough.

  20. WBS is a hierarchicaldecomposition of the project work, based on deliverables.

  21. 1.5.Grouping and Summarization

  22. Grouping is used for organizing things.Organizing things makes it easier to manage them. Managing is not possible without summarized information.We also use groupings to provide summarized information.

  23. Sum Min Max Calc Rollup methods: The appropriate method of rollup depends on the nature of the information.

  24. The fifth core principle of the PRINCE2: Manage by Exception information for executives Higher levels of WBS Summarized information information for project management team Lower levels of WBS Detailed information WBS information for executing team

  25. A well-formed WBS provides appropriate information for each management level involved in the project. A poor WBS couses problems in monitoring and controlling the project. An effective WBS is always deliverable-based. information for executives Higher levels of WBS Summarized information information for project management team Lower levels of WBS Detailed information WBS information for executing team
