How many Green Belts or Black Belt candidates are typically under the responsibility of a Black Belt?

The typical range of Green Belts or Black Belt candidates that one Black Belt is responsible for is indeed 1 to 3. This number allows for effective coaching, mentoring, and oversight, ensuring that the Black Belt can provide adequate attention and guidance to the candidates as they work on their projects. A smaller team enables the Black Belt to maintain a high level of engagement and support, fostering development and effective problem-solving skills among the Green Belts or Black Belt candidates. The balance of this ratio is crucial, as too many candidates could dilute the Black Belt's ability to provide meaningful assistance or deep involvement in each project, while too few might not leverage the full potential of the Black Belt's capabilities and expertise.
