AbstractThis paper considers the orientation of product development structures towards interdisciplinary system architectures using the example of a tool machine manufacturer. Due to the change from simple mechanical products to extensively designed systems, whose successful development requires the integration of all disciplines involved, it is analyzed which requirements there are for these interdisciplinary system architectures in today's development environment. In addition, it is validated on the basis of the investigation environment that interdisciplinary system structures are necessary for the development on the different levels of the system view. In doing so, the investigation environment addresses the concept of extracting customer-relevant features (systems) from a physical-tailored modular system (supersystem) in order to develop and test them autonomously, as well as to transfer them to the entire product range in a standardized manner. The elaboration identifies basic requirements for the development of a knowledge base in interdisciplinary system structures and places them into the context of an agile modular kit development.

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.

In a competitive development environment, a method is needed to quantify the usability characteristics of an interface. This quantification provides a basis for making human factors design recommendations. A methodology for comparing the usability characteristics of product interfaces with those of the competition is presented. The discussion details the steps of a competitive evaluation methodology: (1) definition of interface objectives, (2) development of a flow chart for each product interface, (3) determination of the categories of comparison based on salient and quantifiable characteristics of the interface, (4) derivation of the metrics used for comparison, and (5) the resulting comparative evaluation. The methodology was used to compare the panel (screen) format and navigation characteristics of two network controllers. The value of this methodology and its impact on the way human factors engineers contribute to product development are also discussed.

Abstract Various approaches to capturing and retrieving engineering design information and intent are currently used in industry and play an important role in engineering design collaboration and concurrent engineering. At one end of the spectrum there are expert systems that perform complex analyses of designs based on information that is very specific and specialized for a particular product. At the other end are less automated and less complex non-expert systems. These systems provide the means to organize, collect, and reuse general collections of design intent and rationale in terms of notes, solutions to problems previously encountered, and best practices organized into a database or posted on an internal web site. By surveying the current state of engineering design knowledge management (KM) tools and implementation, conclusions can be drawn regarding the basic elements of successful knowledge management and the opportunities that exist to expand the capabilities and use of such systems in the product development environment. This is of particular relevance to current design practices that are becoming increasingly automated, decentralized, and global. Knowledge management on a large scale will require strategic planning and a deeper understanding to provide the standards for interoperability and exchange that will be needed. This paper provides an overview of approaches to knowledge management in the product development environment.

Abstract U.S. industry spends billions of dollars as a result of poor interoperability between computer-aided engineering software tools. While ongoing standards development efforts are attempting to address this problem in today’s tools, the more significant demand in next-generation tools will be for representations that allow information used or generated during various product development activities to feed forward and backward into others by way of direct electronic interchange. Although the next generation of tools has the potential for greatly increased benefits, there is also a potential for the cost of poor interoperability to multiply. The goal of this work is to develop representations of information that are unavailable in traditional CAD/CAM/CAE tools to support the exchange of product information in a distributed product development environment. This paper develops a vision of next-generation product development systems and provides a core representation for product development information on which future systems can be built.

This paper describes the integration of a producibility and product performance tool in a web service environment. First, we provide a background on web services and a review of product development environments that utilize a service-based architecture. Next, the paper describes the implementation of two services—a process capability database coupled with an aircraft engine fuel nozzle performance model. Discussions close addressing the challenges faced in the current software services development environment.
