This tutorial introduces concepts and methods that can be used to analyse social-technical systems for their vulnerability to failure. We are particularly concerned with socio-technical systems where human error may be an important safety factor. These techniques include work analysis (including task analysis and scenario analysis), human error identification and human reliability assessment. But many of these techniques do not model organisational processes very well. Learning from experience is a valuable input to barrier analysis. It offers a more organisational perspective. We will introduce a safety modelling language as a promising method to meet this need. Aims

To give participants:

  1. An understanding of human activity in complex systems- the problem and the issue for assessment techniques
  2. A practical introduction to Human Reliability Analysis and the THEA method with
  3. An understanding of complex systems for a socio-technical perspective: managing risks processes and Barrier Modelling
  4. A practical introduction to the Safety Modelling Language
