TQ stands for total quality. It is reflective of Deming's ideas and embodied in the Malcolm Baldrige criteria. Some differences between total quality and six sigma are pointed out here. Although there are differences, these two approaches work quite well together. Total Quality tends to focus on culture change, empowering workers and teams and much of the improvement takes place within the departments or functions. Six Sigma focuses on high level cross-functional processes, with involvement from upper management and relies on experts to implement.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
