The purpose of this chapter is to discuss Business Performance Management (BPM) by taking into account its communicative and linguistic aspects. To narrow the scope of the research, the author concentrates on the systemic approaches to highlight the role of communication and language in BPM. To discuss this issue in greater detail, two concepts have been created, namely, the corporate linguistic allostasis and the calibrated corporate linguistic identity, which are used to show the role of corporate identity and communication in business performance management and their implications for creating and sustaining competitive advantage.
