2 1. Purpose The purposes of the KOSMOS Work Breakdown Structure (WBS) are to: Permit allocating and tracking a project-wide budget across project phases and participating institutions that will allow all interested parties visibility into project budget performance at any phase or level of the project. Permit management control of the project during all phases of the project. After the project is complete, permit one to understand what individual major subsystems and deliverables actually cost. 2. WBS Requirements The key requirements of the KOSMOS WBS are as follows: Separate design study phase and fabrication phase. Combine design study and fabrication phases into a single integrated project to understand total project cost without interference (no re-use of WBS numbers across phases). Separate OSU and NOAO work packages, to understand budgets and actual costs of each work package, and sub-work packages assigned to each institution. Combine OSU and NOAO work packages into an integrated project to understand total project cost without interference (no re-use of WBS numbers across institutions). Take the WBS down to a level that provides adequate transparency into the project, but not overwhelming detail so that bookkeeping becomes the primary activity on the project, and uses more than the available digits in the allocated charge numbers. To the extent possible, the WBS should be human-readable and recognizable. Break down all of the work required to complete the project. Include all physical deliverables and their subsystems (but not necessarily as separate WBS elements). For each deliverable, include development, design, prototyping, fabrication, assembly, integration and acceptance testing leading to a deliverable product (but not necessarily as separate WBS elements). Include administration, system engineering, purchasing and reporting not directly tied to deliverable products. Organize work in a way to support delivery of "products", not by activities or engineering disciplines. December 8, 2009 Page 2/13

12 Appendix B NOAO Account Numbers NOAO will have 2 sets of account numbers, corresponding to activities funded from the NSTC base budget and activities funded from the ReSTAR award. The former begin with N-MR110 and comprise everything under WBS 2; the latter begin with N-MR210 and comprise everything else. Accounts will be created and closed as needed according to the following scheme: The first, third, and fourth digits of the WBS number define the last 3 digits of the charge number. For example, a scientist working on the Science Requirements Definition under WBS D.N.2.1 would be charging to N-MR110-D21. Charge accounts will not extend below the second level so (for example) all Detector System Mechanical design phase activities would be charged to N-MR210-D84. WBS elements 10, 11, 12 etc., will correspond to A, B, C, etc. We will produce a list of charge accounts and titles so people do not have to go through this exercise when filling out their time cards (see tentative list at end). When the project cost is estimated from individual task sheets, which will be used to generate a schedule, we will often have multiple tasks for the lowest level of the WBS and certainly for the lowest level of the account structure. This is normal, and to be expected. The WBS implies a total of roughly 60 accounts, plus division into design and construction phases, although not all of these will be active at any one time, and not all accounts will be needed at either institution. Furthermore, any one person is likely to charge only a fraction of the accounts as their contribution to the project.
