Step-by-step explanation:
The business methodology that involves highly trained employees known as Champions, Master Black Belts, Black Belts, and Green Belts is Six Sigma. This disciplined, data-driven approach is designed to eliminate defects, drive improvement, and enhance quality and efficiency in organisational processes. The ranking of belts is similar to the hierarchy in martial arts, with Master Black Belts overseeing Black Belts who lead project teams that often include Green Belts. Six Sigma programs typically focus on manufacturing but can be applied to a variety of industries for process improvement.

Instructional Systems Design (ISD), on the other hand, is a process used to design and develop educational and training programs.
