Combined use of Cognitive Task Analysis and Observational Research Data to Identify Deficiencies of Support for Situation Awareness

Designers require insight into deficiencies of current support for situation awareness (SA) to be able to improve operators’ SA through better system design. The current methods proposed in literature to gain insight into sources of SA errors are not suitable to identify deficiencies in the field of nautical operational network management. This paper proposes a structured approach for syntactic and semantic processing of cognitive task analysis (CTA) data and observational research data to identify deficiencies. The results show that analysis of CTA data and observational research data complement each other and are best used in parallel.
