4M change points poster

A change point is any change in the 4Ms (man or people, machine, material, method): a new operator, a repaired machine, a new material lot, a changed standard. New problems often start right after one. Change point management flags each change before it happens, adds checks while the process settles, and records what was found. This poster lists typical change points under each M and the four steps to manage them.
