Scenario-based design
| Hi-index | 0.00 |
Work analysis is the main approach in ergonomics for needs analysis, specification and validation of work aid tools. Unfortunately, some working situations cannot be studied by means of classical work analysis methods. In particular, when operators are faced with cirtical states in the world, such as forest fires or flood management. The characteristics of these situations are their low frequency of occurence and the high level of stress for the people involved. We propose to adapt work analysis to obtain results without direct obseravtion of operators in real situation, and to build scenarios and carry out simulations for the validation stage of the tool.
