Validating a framework for participatory ergonomics (the PEF).

Participatory ergonomics is reported in an increasing number of case studies, but there is little evidence of emerging supportive theory and relatively little generic advice or guidance. The paper describes an effort to provide clarity and organization to the field of participatory ergonomics. A framework has been developed to define a range of different participatory ergonomics initiatives, establishing a number of levels at which to operate. This participatory ergonomics framework (the PEF) was validated through retrospective description of seven independently conducted case studies and through peer evaluation. The exercise suggests that the PEF can be used as a first basis to produce practical guidance on participatory ergonomics programmes.
