This manual is written to serve as a guide to Ship Design Managers (SDMs), Systems Integration Managers (SIMs), and other design management personnel. It is intended to aid in indoctrination of newly assigned personnel and serve as a source for planning and execution of each design phase for the management of designs for ships being acquired by the Naval Sea Systems Command (NAVSEA) and its affiliated Program Executive Offices (PEOs). The SDM is directly responsible for the successful management of the ship design project and for the final design package. For Warfare or Mission Systems, procured by a different Program Office, the SIM performs a similar function to integrate the systems together to a cohesive warfare or mission system and to work with the SDM to integrate the system into the ship. The SDM and SIM must ensure the development of a fully integrated, technically satisfactory ship and associated system designs that meet the specified performance requirements and cost goals. All SDMs and SIMs including in-service, are concerned with addressing technical issues associated with design deficiencies, modernization, alterations, safe operations of ships and ship systems when using equipment and systems in a non-traditional manner. This manual sets forth ways and means of performing the planning, coordination, and review functions required of SDMs and SIMs presuming sufficient technical knowledge and experience to perform the required tasks. The manual contains generic samples of management products developed for or by the SDM and SIM. General SDM and SIM guidance applicable to all design phases is covered in the main body of the manual. More specific guidance is provided in the appendices. This manual is planned for update every two years.
