This thesis aims to solicit and elicit the view of experienced system safety analysts in the applicability and use of STPA, a hazard analysis derived from the STAMP-framework. The increase in complexity in systems elevates the chance of hazards and risks being obfuscated. Thus, the intention is to expand, deepen and theorize about the STPA-methodology in relation to the role of system safety analysts in Sweden. The results show that the greatest use of STPA might lie in integrating the desired procedural steps with the hazard analysis techniques used today. This is due to individual capabilities, guidance in identification and evaluation of risks, as well as the reductionistic perspective that prevails in society today. Unlike STPA’s claim for completeness, the impression of the system analysts is that absolute safety can never be guaranteed.
