Abstract
The founders of the sociotechnical model perceived its relevance at the macro level of the community, at the meso level of whole organizations, as well as at the micro level of the primary work systems, but it is at the primary work system that most applications have been carried out. An efficient micro level sociotechnical solution may still cause the technology to have a harmful impact on the environment. An increasing popular awareness of environmental damage due to certain technologies leads one to consider an extension of the Important joint optimization concept to a systemic heuristic device called the socioecotechnical model in which the intra and extra-organizational factors can be jointly assessed and optimized.
