ABSTRACT
This fi nal chapter brings together theoretical and practical considerations for all those concerned with specifying buildings. As demonstrated, factors both internal and external to the specifi er ’ s social system may exert different pressures at different stages during the project. Thus, although specifi ers are mainly content to choose from their preferred palette, building product innovations may be forced on them by pressure from, for example, planning offi cers or contractors. Therefore, building product innovations may be introduced by sources other than the manufacturer.
