Abstract

Medical systems incurred accidents may result in significant damage for human being. Therefore, performing hazard analysis is important for medical system which is to identify hazard for preventing the accidents and minimizing the potential harm. Hazard analysis that is applied medical systems are difficult to apposite selected, because difference of analysis methods and applied development lifecycle is caused by objective of hazard analysis. It is required to select appropriate hazard analysis at concept phase during development lifecycle, owing to basic requirement elicitation to mitigate or prevent hazard based on identified hazard at concept phase. In this paper, hazard analysis methods, PHA and STPA, are compared at concept phase in which both methods have been applied on the medical system. As a result of compared methods, hazard analyst can be selected optimized hazard analysis methods for concept phase of the medical systems.
