<p>This report presents a study of the effect of reusing experience in the Hazards and Operability Analysis method (HazOp method) with regards to how the effectiveness of the method is affected. The study was conducted by first creating a software tool for experience reuse in HazOp, then testing that tool in a student experiment in which the participants used the tool when conducting a HazOp.</p><p>During the experiment it was found that students using the tool found 21% more hazards in the system under study than their counterparts. After conducting the experiment it was found that there was a 94% certainty that this improvement was not due to random effects.</p>

<p>The increasing complexity of products and systems today has forced new processes, methods, and tools for managing the development of products. It has also forced the development of complex organisations and diverse relationships among functions and peoples within product development organisations. This implies a need for integrated processes. There is a need to study collaborative product development (CPD) from a holistic perspective, where internal as well as external collaboration are studied as integrated parts of CPD settings.</p><p>Thus, the main purpose of the research project is to facilitate the efficient execution of collaborative product development projects in the manufacturing industry. Further, the objective is to provide a supporting model for analysing and setting up projects in CPD settings. This will enable successful product development in terms of lowering costs, increasing the perceived quality of the product, and improving the timing to market. The focus is on the CPD projects, linking internal and external collaboration.</p><p>A systems approach is applied to the research project to obtain the holistic view needed for addressing the CPD setting. Within the research project, case study research is used as the primary method when gathering empirics.
