2 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P2 - 1 Session Outline What is a WBS and where is it useful? What is successive decomposition? How is the WBS used on a program? How can I tell if I have a good WBS? Numbering notation. Examples. Common errors. Outline

3 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P2 - 2 Where is WBS Useful? Rocket Science? Brain Surgery? CVISN?

4 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P2 - 3 The Work Breakdown Structure Is... “Product-oriented hierarchy of goods and services.” Form: inverted tree; or indented list. Visualizing the entire project. Common framework for planning and control. Vehicle to divide work into tasks that are: Manageable Independent Measurable Integratable Graphically displays entire project. Clear definition of all effort. “Top Assembly Drawing” of the project. “Product Breakdown Structure” or “Project Breakdown Structure” more apt name! Or perhaps “Work Buildup Structure”.

12 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P WBS is The Basis For Cost estimates and budgets. Milestones & schedules. Responsibility assignment. Allocation of resources. Schedule horizontal and vertical traceability. Risk analysis. Concurrence of participants. Integrating the total project effort. Summarizing costs, schedules, performance. Forcing the Project Manager to think through all elements of the project. WBS Definition

13 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P Tests for a Good WBS:  Product-oriented hierarchy of goods and services.  Top level may be dictated by contract.  Basis for cost estimating, project organization, assigning responsibility, task scheduling, and status reporting.  Basis for understanding and communication.  Each element should be “manageable”.  Based on System Engineering: interfaces are minimized; units are stand-alone testable.  Eliminating one product element will delete the associated costs.  Segregate recurring from non-recurring costs.  Identifies and defines all effort to be expended: correlation of lower levels to specification tree, contract line items, data items, and work statement tasks.  Useful! Reflects the way the work is managed and performed.  Sufficiently low level to establish adequate visibility and confidence for cost estimating, project planning, and project control.  Technical/cost/schedule can be integrated at every level for each element.

Motto: “Yesterday’s Technology Solving Today’s Problems Tomorrow”

16 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P Key Concept: The WBS is a product-oriented, hierarchical list of the work to be done. The program plan is linked to the system design through the upper levels of the WBS. CVISN State System Design Program Scope CVISN State Program Plan Program Implementation Detailed Design by Subsystem Detailed Design Rolling Wave Plans (3-6 months) Detailed Phase Plans Work Breakdown Structure Screening Project Plan Credentials Project Plan Safety Project Plan WBS Concept

19 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P Elements Not to Include in WBS Do not use the structure of the contractor’s organization as the basis of a WBS. At the top levels do not begin by decomposing into the functions or cost categories associated with developing those products. Adapted from Department of Defense Handbook – Work Breakdown Structure, MIL-HDBK-881. Available at: Includes examples from the defense industry. Program DesignBuildTest HardwareSoftware What not to do! Do not use generic names -- use actual system names and nomenclature. No disembodied software -- software developed to reside on specific equipment must be identified as a subset of that equipment. WBS Definition

20 CVISN Planning Workshop The Johns Hopkins University Applied Physics Laboratory Day 0, P2 Work Breakdown Structure Review & Prep! 4/13/2015 5:28 PM P Common Errors When Creating WBS Does not include all of the work. Example: The project calls for a prototype and a final version, but the WBS shows only one of these. Or it shows the prototype in detail, and then simply lists the other without showing the work needed to produce it. The level of detail is not sufficient to manage the program. Example: The big pieces may be there, but they are not broken down sufficiently to enable the work to be assigned, tracked, and managed. (The test would be: Can you use this WBS to make a good, detailed CPM network?) Important but not readily apparent steps are left out. Example: The omission of integration and testing. The work is there, but it’s not arranged logically. Example: Lower-level product integration and testing is there, but its off on its own and you cannot tell what it is to be applied to or when.
