Distributed systems are growing increasingly complex in the sense that they need to reorganize on a regular basis to respond to external opportunities. At the same time research has shown that performance is improved where technology support is aligned to people's activities within the system. This paper provides a framework for ensuring that such alignment is maintained during system evolution. The paper first defines the nature of change using complexity theory as the foundation for defining the nature of change. It then builds on the idea of socio-technical gaps to identify the gaps created by a change. The changes are then outlined in terms of perspectives to provide a systematic basis for managing change. To do this change is expressed in terms of the perspectives to provide a meaningful way to respond to change.
