Which Practice Area focuses on sustaining the changes achieved in an organization?

The Practice Area that focuses on sustaining the changes achieved in an organization is "Sustaining Habit and Persistence." This area emphasizes the importance of not just implementing changes but ensuring that these changes become ingrained in the organization's culture and practices over time. It involves creating habits that support new behaviors and processes, enabling the organization to maintain improvements and continuously build upon them.

Developing a culture of persistence is crucial, as it encourages individuals and teams to keep practicing the new approaches, thus avoiding regression to past behaviors. This focus on sustainability is essential in any organizational change initiative because it helps embed new practices firmly and prevents the organization from reverting to outdated methods.

In contrast, the other Practice Areas, while important, do not specifically address the ongoing effort required to sustain change. For instance, Implementation Infrastructure deals more with the frameworks and systems needed to enable implementation. Configuration Management pertains to managing changes in product configurations rather than ensuring lasting change in organizational processes. Supplier Agreement Management focuses on managing relationships and agreements with external suppliers, which is a different aspect of organizational change.
