The Naval Sea Systems Command (NAVSEA) promulgated the Ship Work Breakdown Structure (SWBS) in 1973 to provide a single language to span the entire ship life-cycle from early design and cost studies through disposition. This system and its predecessors have been primarily used as an accounting system for weight and cost estimates in the latter stages of ship design, i.e., contract and detail design. The position is taken that the SWBS system can be the center of the logical approach to ship design for each and every phase of the design. Using this approach, systems engineering and ship integration can be accomplished by ensuring the consideration of each functional area in the early stages of design. A matrix approach is developed which tracks the design by looking at each functional area for various system disciplines, such as cost, manning, survivability, reliability, et cetera. The overall approach allows for the disciplined analysis of each functional area of the ship with decisions and selections made by using a ship system/ship impact oriented design philosophy. Properly set up and orchestrated, this logical approach should lead to a thoroughly developed and balanced ship design which is managed by initially putting everything from R&D, weight estimating, cost, et cetera into the system that becomes even more valuable as the design matures, i.e., SWBS.
