What role do 'Green Belts' play in Six Sigma?

In Six Sigma, 'Green Belts' play an essential role by participating in project teams under the guidance of Black Belts. They usually have a solid understanding of Six Sigma principles and tools, enabling them to contribute effectively to process improvement projects. Green Belts often operate in their regular jobs while managing project responsibilities part-time, which allows them to apply Six Sigma methodologies directly to their work processes. This involvement helps drive project success and promotes a culture of continuous improvement within the organization.

In contrast, other roles such as leading major projects or being solely responsible for training are typically associated with higher-level certifications, such as Black Belts. While conducting audits may be part of a broader quality assurance function, it is not the primary focus of Green Belts within the Six Sigma framework. Their main contribution lies in teamwork and collaboration, supporting the Black Belts in achieving project goals.
