Requirements of SPCįor the first part of our statistical process control tutorial you need to look at the implementation levels. Setting up Statistical Process Control is a process in itself, calling for organizational dedication across functional limits. Quality data is acquired in the form of product or procedure capacity right away during production. Clearly, I can see I’m wasting my time on this forum.Statistical Process Control (SPC) is an industry-standard approach for assessing and managing quality throughout the production process. No wonder Six Sigma is in decline if Satish’s reply is considered the correct one. It didn’t work then and it won’t work now!
I know from my own personal expeience of over ten years that trying to ‘sell’ X-bar and R charts just doesn’t work. The worse thing ever to happen to USA quality was a small, little man, reporting what he thought should happened in the development of Motorola’s Six Sigam efforts, rather than what actually happened.
Do you think Motorola provided ten years of Juran training, hired several statisticans, and quality managers, yet failed to satisfy Ford and GE prior to 1984? Think about it!!! I know what works and doesn’t work – not from books – but from practical experience.
You ought to be able to deduce this yourself quite easily!įor example, who gives specific examples, and who just reguritate stuff from textbooks written by quality auditors! What I find surprising is others are making recommendations that don’t actually work. Some of us have actually achieved something in this field. The reason I ask is because there is a lot of deception on this website. The point is show / demonstrate people that because of control charts there has been benefits. You start with one of these -> I-MR or X bar R or X bar S chart.ĥ) Plan for 2 hrs of class room training and 2 hrs of shop floor work where they collect sample and plot the chart.Ħ) Keep doing this on a regular basis till all the citical parameters are covered.ħ) Once implemented, have a frequency of checking these charts and updating the control limits.Ĩ) As this progresses train people on how to interpret these trends and take suitable action.ĩ) Slowly start replicating this to other areas. Its good that you have looked at applying SPC in you company.ġ) We should start in a small way – choose one are or cell or lineĢ) Choose those critical parameters which needs to be monitored.ģ) The operators who need to plot should be trained in the first place.Ĥ) Plan a session 4 hrs, where you teach them in simple language, what is the importance of control chart and how to plot it.
