  1. Work Breakdown Structure (WBS) Farrokh Alemi, Ph.D. Lee Baliton

  2. Why break up? • Improve work management • Understand resource and time constraints • Set milestones for progress • See alternative sequencing of components of work

  3. Definition of WBS • Breaks the project scope • Inter-related • Discrete tasks • Hierarchical tree structure

  4. Definition of WBS Clear starts and ends • Breaks the project scope • Inter-related task • Discrete tasks • Hierarchical tree structure

  5. Definition of WBS Four possible relationships • Breaks the project scope • Inter-related • Discrete tasks • Hierarchical tree structure

  6. Definition of WBS Four possible relationships • Breaks the project scope • Inter-related • Discrete tasks • Hierarchical tree structure • Finish to Start: Start second task after first one is finished

  7. Definition of WBS Four possible relationships • Breaks the project scope • Inter-related • Discrete tasks • Hierarchical tree structure • Finish to Start • Start to Start: Start second task same time as first one

  8. Definition of WBS Four possible relationships • Breaks the project scope • Inter-related • Discrete tasks • Hierarchical tree structure • Finish to Start • Start to Start • Finish to Finish: Start second task so both finish at same time

  9. Definition of WBS Four possible relationships • Breaks the project scope • Inter-related • Discrete tasks • Hierarchical tree structure • Finish to Start • Start to Start • Finish to Finish • Start to Finish: Second task cannot finish before first one starts

  10. Definition of WBS Lower level tasks inherit the relationships among higher level tasks • Breaks the project scope • Inter-related task • Discrete tasks • Hierarchical tree structure

  11. Hierarchy of Activities Level 1: The root of the tree is the project name A

  12. Hierarchy of Activities EHR implementation A

  13. Hierarchy of Activities EHR implementation Level 2: Components of the entire project A B C D

  14. Purchase system Train users Configure system Hierarchy of Activities EHR implementation A B C D

  15. Purchase system Train users Configure system Hierarchy of Activities EHR implementation A Level 3: Each level 2 tasks is broken into its subcomponents B C D E F

  16. Hierarchy of Activities EHR implementation A Purchase system B C D Train users Configure system E F Purchase training material Detail employees

  17. E Purchase training material Hierarchy of Activities EHR implementation A Purchase system B C D Train users Configure system F Detail employees

  18. E Purchase training material Hierarchy of Activities EHR implementation A Purchase system B C D Train users Configure system F Detail employees

  19. A D C E B Hierarchy of Activities EHR implementation F Detail employees Train users Purchase training material Configure system Purchase system

  20. Approaches to Developing Work Breakdown • Guidelines • Analogy • Bottom up • Mind mapping

  21. Approaches to Developing Work Breakdown • Guidelines • Analogy • Bottom up • Mind mapping

  22. Approaches to Developing Work Breakdown • Guidelines • Analogy • Bottom up • Mind mapping

  23. A D C E B Hierarchy of Activities EHR implementation F Detail employees Train users Purchase training material Configure system Purchase system

  24. EHR implementation A Train users D F Detail employees Purchase training material C Configure system E Purchase system B Hierarchy of Activities

  25. Approaches to Developing Work Breakdown • Guidelines • Analogy • Bottom up • Mind mapping

  26. Task • Mutually exclusive • Exhaustive

  27. EHR implementation A D Train users C Configure system B Purchase system Task • Mutually exclusive • Exhaustive Purchase of systems and organizing training may not be mutually exclusive if the purchase includes training

  28. Task • Mutually exclusive • Exhaustive

  29. Breadth .vs. Depth • Focus on breadth • Let details emerge • Progressive elaboration • Creativity

  30. Breadth .vs. Depth • Focus on breadth • Let details emerge • Progressive elaboration • Creativity

  31. EHR implementation A Train (detail)users D C Configure system Purchase system B Numbering Convention 1.1.2 Purchase training material E

  32. EHR implementation A Train (detail)users D C Configure system Purchase system B Numbering Convention 1.1.2 Purchase training material E

  33. EHR implementation A Train (detail)users D C Configure system Purchase system B Numbering Convention 1.1.2 Purchase training material E

  34. EHR implementation A Train (detail)users D C Configure system Purchase system B Numbering Convention 1.1.2 Purchase training material E

  35. Work Breakdown Is Not … • We need to clarify some common mistakes …

  36. A Task Is … • Not a goal

  37. A Task Is … • Not a goal • Not a process

  38. Work Breakdown Is … • Not an exhaustive list of work

  39. Work Breakdown Is … • Not an exhaustive list of work • Not a chronology

  40. Work Breakdown Is … • Not an exhaustive list of work • Not a chronology • Not an organization structure

  41. Work Breakdown Is … • Not an exhaustive list of work • Not a chronology • Not an organization structure • Not to be changed often

  42. Good Work Breakdowns • Easy to understand • Corresponds to job descriptions • Not too detailed • Preserve the most important relationships among the tasks • Does not add to length of project

  43. Take Home Message Think Carefully through Work Breakdown Structure
