To help bring down their cost, it is important for Mobley Industries to find what total quality management (TQM) activity brought down their product defects. If they can find what change brought down their defects, they may find the source of which increase their product costs. However, in often times decreasing defects if they have to do with adding extra labor, steps, or parts will increase the cost without allowing for change. If they can pinpoint where the increase is coming from though, they may be able to find a better more cost effective solution.
