Six Sigma

Working on PIUSS PMA I read a lot about 6 sigma. Somebody asked what it was and I was trying to explain. SOmething that comes to my mind that I think it is quite interesting is the idea that a method that started basically as statistical control of processes evolved to became a sort of philosofical way of thinking management. It became something bigger, broader. The concept evolved and could be used to all process in te company.

I have only two strong criticisms to it. First the most common way to address it have little concern for human related issues. It needed a bit more of soft skills in my opinion. Second, I think variation works well for the average and mass production. But human beings are individuals, hard to establish limits, averages for several activities that are basically human. For example, assuming everything is a system, every system has processes that are measurable. But and if this system has someone fantastic, a genius? 

Just thinking.

  1. Understand where you are coming from Fransico. Another point to consider is what Deming thought of the six sigma approach, he said it could never be sustained as it comes down to greenbelts and blackbelts to deliver the improvement therefore when they moved on the improvements were lost, pshycology plays a huge part here I think, if the people do not feel they want to improve i.e. leadership supports improvement culturally then it is irrespective whether six sigma improvements are delivered or not as Deming would say the business is doomed to fail anyway.
