In relation to Six Sigma, what does the "Control" phase typically involve?

The "Control" phase in Six Sigma is essential for ensuring that the improvements made during the project are not only achieved but also sustained over time. This phase involves establishing measures, such as key performance indicators (KPIs) and control charts, to monitor the process and maintain the gains that have been achieved. By creating a system for ongoing monitoring and providing the necessary feedback mechanisms, teams can ensure that variations are kept in check and that the processes operate within the desired standards.

In this phase, organizations often also develop training and communication plans to keep all stakeholders informed and engaged. This proactive approach helps to embed the improvements within the organizational culture, preventing regression to previous states and ensuring the long-term success of the Six Sigma initiative. Thus, option B is the most appropriate and encapsulates the core intention of the Control phase within the Six Sigma framework.
