Dear Mr Venkat I fully agree with your explanation ogf control chart. control limits are depending on sigma and not customers LSL & USL Regards

Control chart tells at what point test fails. which is due to special cause variation, one can see and go back to see what different happened at that particular opbservation. for failing. Then you can attend the problem and agin run the control chart so that all the points on the graph will lie between LCL & UCL. also see the moving range chart(I-MR) also hepfull to study the process

My openion:- 1) Management is not giving priority for deployment of six sigma 2) It si wrong thought that six sigma is only GB's entity. everybody forgetsSix sigma is a team work . 3) Some thinks that there are no problems, whatever we are doing is the best. 4) concept is not clear to management. It si very difficult to deploy- awrong thought.on the basis of perception. 5) Thinking as atime waster activity. Anybody want to add???

following are the reasons for considering as Six sigma ,infact it is beyond Six sigma if you consider Defect rates & DPMO 1) Error rate 1 in 16 million transactions. 2)Six Sigma performance 99.99999 3)No techgnological back up 4)Cost of service Rs 300-400 /month ($ 6 to $7 /month only) 5)standard price for all irrespective of distance, weight and space . 6)earning Rs 5000-Rs 6000/ month 7) Rs 36 crores turnover 8) Zero % fuel,Zero % investment,Zero % Moderen technology,Zero %Disputes 9) 100 5 costomer satisfaction. 10)Most influence meal distrubution sytem 11) coding system uses mistakeproofing method. 12) No error in decoding of code on the tiffin Regards Ravindra B.
