Customarily, within the manufacturing domain, Ergonomists design roles based on socio-technical principles, whereas process engineers and managers usually use the ‘left-over’ principle. Both of these are essentially ‘one-off methods, with little connection to modelling and simulation environments. Clearly, a link to Enterprise Modelling within the IT domain would be very useful (e.g. CIM-OSA, GERAM). We report on a completed 1-year pilot study investigating an approach to link job design to enterprise modelling technology. This is based on the concept of the organisation as a ‘knowledge engine’. The approach was tested on job design in two locations, a manufacturing cell in a SME and a process line in a LE. We report on the latter.
