This book’s core argument is that an organization’s physical workspace is an underappreciated managerial lever best understood through a conception of organizations as ecologies (Alexander and Price, Introduction). I have argued (Ch. 1) that those ecologies can be understood via the emergence of cognitive communities (cf. Breslin, 2010) that are enabled by shared interpretations of key signiﬁ ers or narratives. FM is a label that can, indeed the editors would say should, express the process of using workspace to assist in the achievement of an organization’s goals. It is, however, a label redolent with its own contradictions (cf. Vischer, Ch. 3; Cairns, Ch. 8) that arguably provides an example of the very emergence of separate, socially constructed communities and helps corroborate the theory of organizational ecologies. Other chapters discuss the strategic contribution of space. My purpose here is only to examine the emergence of FM and the various discourses that have developed therein, as an example of emergent cultural evolution. It displays, I suggest, an example of mutation of meaning.
