Abstract:
Recognition of the need to effectively develop and deploy new capability within large BAE SYSTEMS projects has lead to the development of several lifecycle management processes. Many of these processes are generic and open to interpretation, or large and unwieldy. The Capability Development and Deployment Process (COOP) evolved to amalgamate many of these mandatory lifecycIe processes but in doing so became a large complex business process in itself with issues regarding representation, usability and decision making. The hypothesis of this thesis is that a Decision Support System (DSS) could be developed to resolve issues of representation, usability and decision making associated with large complex business processes such as the CDDP. In proving the hypothesis, a 'proof of concept' DSS has been developed and evaluated from 'personal', 'technical' and 'organisational' perspectives as a tool for use by managers that reduces the apparent complexity of the CDDP, bridges islands of knowledge, alleviates bias and misconception, and facilitates the progression of a new capability through development to deployment. Key to the success of the 'proof of concept' DSS was the research methodology and design approach taken, which involved the selection and implementation of appropriate tools and techniques. This included the development of a standardised version of the CDDP using IDEFO modelling format, the development and utilisation of a Bayesian Belief Network in a novel approach to decision support for project maturity, and the development of a graphical user interface to remove the user from the complexity of the CDDP, aid navigation through the process and provide multiple cues to aid decision support. The original paper based version of the CDDP along with the equivalent IDEFO representations are provided on the CD accompanying this thesis. A complete version of the 'proof of concept' Decision Support System could not be supplied due to licensing restriction of the commercialoff- the-shelf (COTS) tools embedded within the application (Systems Architect and Netica). However, the software can be made available for demonstration at Loughborough University on request.
