Which title is associated with the coaching function in Six Sigma?

The title associated with the coaching function in Six Sigma is Master Black Belt. This role is crucial for mentoring and training both Black Belts and Green Belts, ensuring that they understand the methodologies, tools, and techniques of Six Sigma. Master Black Belts possess deep knowledge of the Six Sigma principles and are tasked with strategic roles that include developing training programs, aligning projects with the organization's goals, and leading improvement initiatives.

Master Black Belts are expected to not only apply Six Sigma tools effectively but also coach others in their usage, facilitating the growth of skills among team members. This ability to mentor and guide teams is foundational to the successful implementation of Six Sigma practices across an organization, helping to enhance overall performance and foster a culture of continuous improvement.

In contrast, while the other titles—such as Green Belt, Six Sigma facilitator, and Quality engineer—play important roles within Six Sigma projects, they are not primarily focused on the coaching aspect. Green Belts assist with data collection and analysis within projects, and a Six Sigma facilitator typically leads project teams but may not be involved at the deeper coaching level that a Master Black Belt provides. Quality engineers generally focus on ensuring product and process quality but do not specifically encompass the broader training and coaching responsibilities attributed to Master
