Improvements of quality management with six sigma on Tata Boeing aerospace ltd

Description: Quality is important in achieving competition in the domestic and global markets. Quality is a journey that starts from design, to conformity, and ends at superior performance. This process considers quality to be a 'never ending' improvement. The success of quality management mainly depends on the achievement of internal as well as external customer satisfaction. Internal customer satisfaction is a prerequisite for achieving external customer satisfaction. If employees have to identify and fix quality problems, they will have to use some quality equipment. Quality circles are also known as task improvement or quality teams. The quality cycle is a small group of employees who voluntarily meet at regular times to identify, analyze and resolve quality and other problems in their work environment. Six-sigma is a statistical concept that measures a process in terms of faults. Achieving "Six Sigma" means that your processes are delivering only 3.4 defects per million opportunities (DPMO) - in other words, they are almost fully functioning. Sigma (Greek letter) is a term in statistics that measures standard deviation. In its commercial use, it points out defects in the output of a process, and helps us understand how far the process is from perfection. A sigma represents 691462.5 defects per million occasions, which translates to only 30.854% of non-defective outputs. This is clearly a poorly performed process. If you have a three sigma level working process that means you are allowing 66807.2 errors per million opportunities, or 93.319% non-faulty output. It is much better, but we are still wasting money and disappointing our customers. The central idea of Six Sigma management is that if you can measure defects in a process, you can systematically figure out ways to eliminate them to achieve a quality level of zero defects. In short, Six Sigma is several things:  A statistical basis of measurement: 3.4 faults per million opportunities  Method A symbol of methodology and quality
