This document discusses enterprise change management (ECM). It begins by defining organizational change and explaining that change has increased due to factors like technology and customer expectations. ECM is presented as an emerging approach that institutionalizes change management across an organization rather than just on projects. Key aspects of ECM include developing change management competencies organization-wide, treating change as business as usual, and having adaptive leadership. The main challenges to ECM are transforming organizational culture to be more trusting of change and developing leadership and accidental manager skills to operate in complex change environments.
