BME is definitely value-add
The BME course offers a strong foundation in decision-making tools and would be an excellent addition to the Black Belt curriculum. Integrating it into the BB program would significantly enhance mentors’ confidence and effectiveness when guiding projects, leading to more informed and robust decision-making.
