The adaptive systems theory is commonly applied to the control of complex technical systems such as autonomous vehicles. In such cases, the environment of the system is in constant change and the system needs to transparently respond to these changes in order to timely fulfill its objectives. Organizations, considered socio-technical systems, also operate in a dynamic environment. Organizational theory, however, usually regards change as a process and not as an inherent characteristic of the system, addressing the need for change instead of transparently embedding it into system design. This work addresses this issue in the performance management function of an organization by proposing an architecture for information systems based on the adaptive systems theory that intrinsically treats change. In particular, this is accomplished in the metrics and assessment procedures of the performance management function. Metrics and procedures, in this sense, may change over time and are not the result of a deliberate change process, but of the way that the performance management function is implemented through this architecture using an enterprise engineering approach. A proposal for the application of this architecture is presented in the service sector, more specifically related to the Brazilian public education, and the extension of this architecture to encompass other types of organizations and functions is discussed.
