Abstract
Involving perspectives into risk analysis brings a potential to increase the efficiency of the risks analysis task and confidence in the identified risks. In this paper, we report the results from an experiment designed to investigate if Perspective-Based Risk Analysis (PBRA) that involves different views and perspectives is more effective and offers higher confidence than Traditional Risks Analysis (TRA). 43 subjects performed risks analysis of a software-controlled train door system using either TRA or PBRA. We measured the effectiveness of the methods by counting the number of relevant and non-relevant risks. Using a questionnaire, we also assessed the difficulty of the methods and the confidence of the subjects concerning the... (More)

We measured the effectiveness of the methods by counting the number of relevant and non-relevant risks. Using a questionnaire, we also assessed the difficulty of the methods and the confidence of the subjects concerning the correctness of the identified risks. The results suggest that PBRA helps to identify more relevant risks than TRA. On the other hand, our experiment failed to provide supporting evidence that PBRA helps to identify fewer non-relevant risks . Contrary to expectations, this study did find with a statistical significance that PBRA is more difficult to use than TRA. (Less)
