PIUSS module is an interesting one. I still miss more specific discussions but it is obviously impossible to do it with 24 people around.
I liked the guest speaker but I have got to make a comment about the first one. He is the owner of a consultancy that helps in the implementation of process improvement solutions. His material is very good (and I`ve see material from other places, but I think his material is better). But he has he same problem most consultants have. Even though he consciously and rationally would not say that his solution is not complete, not perfect and is not able to solve everything (because it is OBVIOUS that there is no complete solution in the world) he still, quite often, criticises other approaches in a way that seems to insinuate his is the complete, the vest one. It is logical that he likes and thinks his approach is the best, but just as any other serious and structured approach it has gaps and flaws. I`ve seen quite a few presentations from consultants. I`ve worked enough time to know how they talk, what is the speech. And there is always this kind of "My solution is the best, and the others are incomplete because they don`t consider that and don`t think about that other thing." His competitor would say the same about his...
I think six sigma, specially with that Deming approach that actually puts more attention on the system of profound knowledge then in the statistics or DMAIC, DFSS, is a very interesting and clever approach. It is capable of great things (with all the needed support in place) however just like any other method it has its flaws. Them it comes a big question. Is Deming complete? I really don`t think i know enough to answer that question but I will use one of Deming`s principles, the theory of knowledge, to give an idea based on my theoretical thinking. Based on that the answer would be NO, Deming is not complete because nothing is complete, the world changes ideas and science evolve. But from my EXTREMELLY small knowledge I must admit that as time passes I agree more and more with him. Some of the things I did not connect first are making more sense now. But I`m not sure if Deming had this consultant posture they all have and our friend on Monday also had.
Now, just to be and add a bit controversy. This whole idea of "my-model-is-amazing-and-complete-and-much-better-and-wiser-them-the-other-models-and-consultants-around" reminds me a bit of religion. Don`t they all work a bit like that?
