The aim of the ‘Human factors in safety – efficiency and operability’ (ProHF) research and development project was to evaluate how the Human Factor (HF) interventions implemented in three organizations had affected organizational performance.

We evaluated the development phases, current status, impacts, and functionality of the HF activities, as well as the learning processes of three air navigation service, airport operation and rail fleetcare organisations. We used interviews, document analysis and workshops as our methods. We also created 11 organisational indicators to assess the HF activities of the organisations.

The results can be utilized broadly at Finnish workplaces in the fields of industry and social and health care, which constantly face occupational safety risks and could utilize new ways of action and thinking in safety management to even better utilize the human element as part of safety improvements. Safety-critical fields that already have mandatory requirements for implementing HF (railway, aviation, nuclear industry, maritime) can improve their mastery of HF as part of their safety management policies and practices.
