Product-oriented Work Breakdown Structure Pdf Download
084f2db8c6 Example from MIL-HDBK-881, which illustrates the first three levels of a typical aircraft system. . In a Work Breakdown Structure such elements (activity or deliverable), also known as work packages, are the items that are estimated in terms of resource requirements, budget and duration; linked by dependencies; and scheduled. Since the planned outcomes are the desired ends of the project, they form a relatively stable set of categories in which the costs of the planned actions needed to achieve them can be collected. The development of the WBS normally occurs at the start of a project and precedes detailed project and task planning. Design principles. The work represented by the activities in each work package must add up to 100% of the work necessary to complete the work package. . For example, shipbuilding for the U.S. WBS is a hierarchical and incremental decomposition of the project into phases, deliverables and work packages. ^ MIL-STD-881C, Work Breakdown Structures for Defense Materiel Items, 3 October 2011, 3.1.4 ^ MIL-STD-881C, Work Breakdown Structures for Defense Materiel Items, 3 October 2011, 1.4.1 ^ MIL-STD-881C, Work Breakdown Structures for Defense Materiel Items, 3 October 2011, 22.214.171.124 ^ MIL-STD-881C, Work Breakdown Structures for Defense Materiel Items, 3 October 2011, Fig.3-6 ^ MIL-STD-881C, Work Breakdown Structures for Defense Materiel Items, 3 October 2011, Fig.3-1 ^ MIL-STD-881C, Work Breakdown Structures for Defense Materiel Items, 3 October 2011, Appendix E ^ Gilmer, Thomas (1982-08-04). Defense Materiel Item categories from MIL-STD-881C are:.
At the juncture of the WBS element and organization unit, control accounts and work packages are established and performance is planned, measured, recorded and controlled. A WBS can be expressed down to any level of interest. Example of a product-oriented work breakdown structure of an aircraft system. The WBS construction technique employing the 100% rule during WBS construction. A WBS is not an exhaustive list of work. It specifies what will be done, not how or when. 1.1 Air Vehicle 1.1.1 Airframe 126.96.36.199 Airframe Integration, Assembly, Test and Checkout 188.8.131.52 Fuselage 184.108.40.206 Wing 220.127.116.11 Empennage 18.104.22.168 Nacelle 22.214.171.124 Other Airframe Components 1.n (Specify) 1.1.2 Propulsion 1.1.3 Vehicle Subsystems 1.1.4 Avionics 1.2 System Engineering 1.3 Program Management 1.4 System Test and Evaluation 1.5 Training 1.6 Data 1.7 Peculiar Support Equipment 1.8 Common Support Equipment 1.9 Operational/Site Activation 1.10 Industrial Facilities 1.11 Initial Spares and Repair Parts . The figure on the left shows a work breakdown structure construction technique that demonstrates the 100% rule and the "progressive elaboration" technique.
