Objectives and Approach

The KADS-II project will deliver a methodology that covers the life-cycle of KBS projects, provides standards both for project control and system development, and bridges the gap between KBS development methods and other methodologies. By thorough validation and active dissemination efforts, the project aims at making the KADS-II methodology the accepted standard for KBS development in the European IT industry.

The approach taken in KADS-II is derived from that developed within project 1098, KADS, which stressed the idea of an iterative process of methodology construction. The methodology rests upon a theoretical description of KBS construction in terms of a number of models describing different aspects of a KBS. These models, constructed at varying levels of abstraction, lead to a complete set of methods and techniques which support the process of KBS development. A major objective of the project is to further develop this theoretical basis in such a way as to facilitate a formal specification of the model to support prototyping as a development technique, and to enable the optimal use of reusable components. Recent insights in areas such as generic tasks, problem-solving methods and second-generation KBS techniques will be incorporated. Throughout its duration KADS-II will deliver a number of systems based on the methodology

In addition, the project recognises the important issue of acceptance and usability of the methodology. Results will be validated through an active systems development programme and an on-going process of dissemination. A major theme of the project is to facilitate acceptance of the methodology by ensuring that its tools and techniques are compatible with more conventional approaches to systems development in terms of both delivery environment as well as structure and contents.

Progress and Results

A unified knowledge modelling approach has been established with supporting tools (CommonKADS model set, common modelling language, ML2). A KBS development life cycle including risk and quality management concerns has been defined. The library of generic task (ie diagnoses, assessment, configuration, modelling, design) is being populated and the KADS tools are now integrated in the workbench architecture. The method and tools are under extensive experiments in order to assess them in concrete industrial context and provide feedback for further improvements in the computer-based tool support for common KADS.

Exploitation

Relying on the growing success of the KADS methodology (the SHELLEY workbench developed in project 1098, KADS), the industrial partners of the project have started:
