lean six sigma using sigmaXL and Minitab

Business production methodologies have never stopped improving since Frederick W. Taylor, the inventor of scientific  management, devised techniques for factory management and time and motion studies. Eli Whitney created the methods for interchangeable parts and Henry Ford developed the modern assembly lines used in mass production today. These inventions were the precursors of the modern day quality and productivity improvement methodologies. Over the past three decades, many managerial methodologies aimed at improving production processes have been introduced to businesses throughout the world. Some have resisted skepticism and have prevailed and are still being used, while others, such as the total quality management (TQM) or company wide quality control (CWQC), have been deemed to be nothing but fads and have disappeared almost immediately after they appeared. In fact, all the process improvement strategies (Six Sigma, TQM, CWQC, Lean, TOC, etc.) have the same underlying philosophy; they are all geared toward customer satisfaction and insist on the necessity for all sections of a company to cooperate in order to improve all aspects of its operations. They all insist on producing high-quality products at the lowest possible cost through a reduction of waste and continuous improvement.
