This research investigates whether the knowledge-based decision support system (KBDSS) paradigm provides the necessary supporting structure and developmental framework for product development evaluation. To address the research questions posed in this study, it is necessary to develop and implement KBDSS's at specific decision points along the product development cycle. This paper describes the design, development, and implementation of a KBDSS to support a product development manager's decision concerning full-scale development of a new product. From the systems design perspective, this paper addresses the integration and innovative use of a variety of techniques for knowledge acquisition, modeling, and processing. The approach utilized obtains the benefits of normative modeling as well as the flexibility and developmental advantages of knowledge-based systems. Since its implementation, the system has been successfully used by a development manager to support his recommendation for an ongoing project. His complete satisfaction with this system served as the impetus for the design and development of a multi-expert system which was implemented at the strategic level.

    • "If effective a PQKB will improve individual and organizational learning via its ability for increased storage and transmission capacity, and will tend to lead to more timely and better quality decision making (Huber, 1990). These positive effects are contingent upon the presence of appropriate planning and control mechanisms (Liberatore and Stylianou, 1993), and effective and strategically important implementation (ref). {better lit review, esp. of TQM-specific studies} We propose that the presence of a PQKB will enhance the quality performance of both the targeted, focal process, as well as other processes that are similar to the focal process.

    ABSTRACT: While organizations have focused increasing attention towards the acquisition and use of process knowledge for the purposes of quality performance, significant advances in information systems have occurred. The emergence of these two forces creates an opportunity for organizations to benefit from the integration of information systems and quality systems. The basic purpose of an information system is to acquire and represent knowledge. The basic purposes of a quality system are quality planning, quality control, and quality improvement. We therefore define a process quality knowledge base (PQKB) as an information system that acquires process knowledge and represents it for the purposes of quality planning, quality control, and quality improvement. This article proposes that the presence of a PQKB can improve the quality performance of the focal process, as well as the quality performance of processes similar to the focal process. We argue that the degree to which a PQKB can effect quality performance is moderated by the richness of the process description encapsulated inside the PQKB, and the diversity of knowledge sources that are engaged during the construction and use of the PQKB. Managerial and research implications are highlighted.

    • "Such systems will tend to improve learning via increased storage and transmission capacity, and sometimes lead to more timely and better quality decision making [12]. These positive effects are contingent upon the presence of such factors as user participation, senior management commitment, project management, system performance, training, and validation [35]. Thus the effective implementation of a PKB depends on careful attention to its design, implementation, and support. "

    ABSTRACT: This paper reports on the development of Lifenet, a knowledge-based decision support system (KBDSS) for the risk assessment of adolescent suicide. Lifenet combines aspects of expert system and decision support technology, and applies them to the social service domain. Assessment is a core task in the social service industry, and its complex nature, combined with the growing use of paraprofessionals as caseworkers, provides several likely domain areas for KBDSS technology. Lifenet's main functions are to provide paraprofessional caseworkers support in reaching unbiased and consistent risk assessments, and to recommend a course of action on the part of the caseworker. The KBDSS was tested by social service professionals using actual cases, and in a controlled experiment with paraprofessionals. Paraprofessionals using Lifenet made more accurate assessments in less time than did paraprofessionals using manual assessment tools. This paper discusses the background, design, implementation, and validation of Lifenet, and presents ideas for future work.
