The Naval Sea Systems Command (NAVSEA) began an initiative titled "Affordability Through Commonality" (ATC) in 1992. The effort's long-term goal is to improve the process by which the Navy, with industry's help, will design, acquire, and provide lifetime support for the ships required for national defense. The technical approach considers commonality to be a synergistic combination of the elements of modularity, increased equipment standardization, and process simplification. A division within NAVSEA (SEA 03R3) was created to coordinate efforts towards this fleet affordability goal, specifically to (a) identify and develop analysis tools for a commonality-based process; (b) assemble resources for initiating a decade-long task; (c) develop a plan for a commonality-based approach to ship design, acquisition, and lifetime support; and (d) implement the plan into the mainstream of the Navy's way of conducting business. This paper provides an interim report on the ATC project's first funded year and the implementation progress of the first program to fully adopt commonality principles, the Advanced Surface Machinery Programs (ASMP), SEA 03Z.

The paper discusses, from a ship designer's perspective, some of the current topics and issues relating to the interface between naval ship design and production. The current environment within which naval ship design activity is taking place is described. Notable current views on Navy ship design and how it might be improved are summarized. Navy design topics pertinent to improving ship producibility, operability, maintainability and survivability are discussed and examples from recent ship designs are. presented. Issues which result from apparent conflicts in current design initiatives and critiques of the Navy ship design process are highlighted and discussed. Finally, some general conclusions are drawn.

A new model for ship design calculations is presented that separates the graphical user interface (GUI) from the calculations (CALC). Design programs can now be defined as more than one interactive graphical user interface tied to one calculation. Several different GUIs can be created for one CALC engine and one GUI can be created to launch several CALC engines in sequence. The GUI of choice is a spreadsheet due to its availability, programmable customization, powerful analysis tools, cross-platform capability, and open code environment.

This paper presents the results of a project that has been carried out under the sponsorship of Panel SP-4, Design/Production Engineering, of the Ship Production Committee of the National Shipbuilding Research Program. Two methods for evaluating the producibility of ship designs and /or ship design alternatives have been developed, one of which provides quantitative results in man-hours or dollars. The other method provides relative results based on weighting factors developed for specific ship projects and the design phase during which the alternatives are being considered. The second, relative, method also can be used for evaluating all of the other parameters which must be considered in making a decision to proceed with any design change, including total cost, performance, schedule, and risk. The two methods are described in some detail and examples of application of each of these two methods to specific design alternatives are presented.

In October 1989, the Naval Sea Systems Command (NAVSEA) conducted the Ship Design for Producibility Workshop with broad participation from the Navy, Shipbuilders, Ship Design Agents and Academia. The Workshop was one of NAVSEA’s first Total Quality Leadership (TQL) initiatives and was subsequently expanded by NAVSEA’s Chief Engineer (CHENG) and the Deputy Assistant Secretary of the Navy (DASN) for Ships into the Ship Design, Acquisition, and Construction (DAC) Process Improvement Project. In addition, the National Shipbuilding Research Program (NSRP) initiated a number of thrusts in Concurrent Engineering and Increased Throughput. The authors describe one of these major process improvement initiatives, NAVSEA’s 3D “Product Model” Strategy to extend throughout the enterprise-wide process of warship development a primary focus on the bridge between ship design and shipbuilding. The Workshop and subsequent process improvement initiatives have had a profound impact on the Naval Ship Design Process. Yet, as reported to Congress in 2002 by the Secretary of the Navy, the unbudgeted cost growth and increased cycle times for Detail Design of new warships have “reached an untenable level”. This necessitated the October 2004 ASN (RDA) policy memorandum on Integrated Digital Data Environment (IDDE). To realize transformational innovations in our ship designs, as well as transformational innovations in the entire warship development process, the National Naval Responsibility in Naval Engineering (NNR-NE) was recently established by the Navy. To support NNR-NE the Office of Naval Research (ONR) and the Naval Sea Systems Command (NAVSEA) created the Center for Innovation in Ship Design (CISD). A summary of some recent CISD Innovation Cells and how CISD can contribute to breaking down the existing organizational cultures and institutionalizing a collaborative product development environment are also discussed. As we begin a new century, it is appropriate that our naval ship design and shipbuilding community review its progress, look at the cross-cut principles of leading change, determine what it takes to bring about dramatic cultural transformation, and discuss the critical need for Navy, Shipbuilder, Design Agent and Academia leadership to continue developing a new collaborative product development environment which fosters a sea change in the whole naval ship development process.

ABSTRACT This study addresses the effect of clawbacks on earnings management (EM). In a two-period model, the manager can report truthfully or distort an interim report using either accrual or real EM. The principal can make short-term payments based on a manipulable accounting signal and long-term payments based on unmanipulable cash flows. The strength of the clawbacks determines the likelihood that the manager's compensation is reclaimed when the interim report was managed. Stronger clawback provisions may result in (1) a substitution between accrual and real earnings management, or (2) earnings management when no earnings management was optimal with weak clawbacks, and (3) lower expected profits for the principal. Numerical analysis suggests that strong clawbacks do not reduce aggregate earnings management. JEL Classifications: J33; M48; M52; G38. Data Availability: All data are simulated.
