GEMS: Outstanding Issues
- GEMS focusses on causation:
- built on Rasmussens SKR model;
- therefore, has explanatory power
- Hollnagel criticises it:
- difficult to apply in the field;
- do observations map to causes?
- Glasgow work has analysed:
- GEMS plus active/latent failures;
- in accidents and incidents.
- Results equivocal, GEMS:
- provides excellent vocabulary;
- can be hard to perform mapping.
