What does the 'Control' phase in Lean Six Sigma focus on?

The 'Control' phase in Lean Six Sigma is essential for ensuring that the improvements made during the process are maintained over time. This phase focuses on monitoring the process performance and ensuring that the improvements are sustained through the implementation of control systems.

In this phase, various tools and methodologies such as control charts, process audits, and standard operating procedures are employed to track key performance indicators and ensure that the process remains within desired limits. By proactively monitoring the process, teams can identify any variations or drifts from the improved performance, allowing for timely interventions to address potential issues before they escalate.

This approach not only ensures that the gains achieved through earlier phases of the Lean Six Sigma methodology are preserved, but it also fosters a culture of continuous improvement, where teams regularly revisit processes and make further enhancements as necessary. The ultimate goal in this phase is to solidify improvements and sustain the benefits realized, promoting ongoing efficiency and effectiveness in operations.
