A specification methodology based on use

This paper describes the work jointly between INRS and CETIM to take risk prevention into account in the specifications drawn up when considering buying or designing work equipment (special machine, individual workstation, assembly line, etc.).
After a brief reminder of this problem and its context, a specification methodology based on use for SMEs / SMIs is proposed. From the theoretical point of view, it is based on the functional analysis method and the concept of work situations as defined by INRS during previous research work. The aim is to encourage the "order giver - designer" binomial to develop, within a dynamic of dialogue, a specification of a work situation and not only of a technical system.
We will present a real industrial application case, showing the methodology simplicity and its effects beyond professionnal risks prevention.
