All projects and programs are designed to deliver lasting and successful change. Yet research on project management confirms that most projects fail to meet the triple constraint (time, budget and scope) and fail to deliver the expected ROI. The most important barriers to success are "soft", people-related factors such as sponsorship, communication and culture. These are more important than "hard" factors such as resources, business process, and technology. This presentation covers the linkage between change management practice and project success, provides tips on diagnosing and addressing resistance to change, presents a framework to understand the factors affecting change capacity (skill and motivation), and describes the key roles, deliverables and best practices for change management within the project lifecycle.
