This book includes management perspectives from outside the field to ensure that the issues raised are seen in an organizational and management context, informing debate within the Facilities Management fraternity. It draws on human ecology and the perspective of the firm as, itself, an intra-organizational ecology of social constructs. The ecology of a firm is not restricted to the firm’s boundaries. It extends to wider relationships between the firm and its stakeholders including, in an age of outsourced building services, the Facilities Management supply chain. This volume offers arguments and evidence that managing such constructs is a key role for Facilities Management and an important participant in the provision of truly usable spaces.
