This paper describes an on-going project with the main objective to develop, implement, and disseminate a freely accessible computer-based assessment tool for physical ergonomics, the Risk Management Assessment Tool for Manual Handling Proactively, RAMP. The project is conducted in seven steps, in close co-operation between researchers and key company stakeholders, using an interactive research methodology. Results include a specification of requirements that the RAMP should meet. Difficulties of developing models of this kind and possible benefits of using such a tool are discussed.
