The contrast was large between the atmosphere and arrangements on these faces and those in the conventional areas of the pit, where the negative features characteristic of the industry were glaringly apparent. The men told us that in order to adapt with best advantage to the technical conditions in the new seam, they had evolved a form of work organization based on practices common in the unmechanized days when small groups, who took responsibility for the entire cycle, had worked autonomously.
# Macrosocial systems. These include systems in communities and industrial sectors, and institutions operating at the overall level of a society. They constitute what I have called "domains". (Trist, 1976a; 1979a). One may regard media as socio-technical systems. McLuhan (1964) has shown that the technical character of different media has far-reaching effects on users. The same applies to architectural forms and the infrastructure of the built environment. Although these are not organizations, they are socio-technical phenomena.
