DATUM

"Dependability Assessment of safety critical systems Through the Unification of Measurable evidence"

Staff and funding

Principal investigator: Prof Alistair Sutcliffe (Now at UMIST) and Prof Neil Maiden
Research staff: Gordon Rugg, Michele Ryan
Funding source:EPSRC
Duration: 1993 to 1996

Project description

DATUM was an EPSRC safety critical programme project which researched dependable systems engineering from 1993-1996 in collaboration with the Centre for Software Reliability and Lloyds Register. Key research directions were methods for assessing system dependability, causal analysis of human error and system failure, and investigation of human reliability in the design process.

Dependability Assessment of safety critical systems Through the Unification of Measurable evidence:

- A taxonomy of cognitive and social factors than influence human error;
- Method and guidelines for safety critical user interface design;
- Empirical studies of errors in designers' reasoning and use of design rationale;
- A method for diagnosing contributions to error arising from people and the user-system interface;

Results from this research have been published widely and exploited in the CREWS project where the taxonomy of cognitive and social factors have been developed into a decision support tool for safety critical design. For further Information contact Alistair Sutcliffe.
