Nasa learns . . . . . Decision of correction or tempering?

Nasa cancelled the launch of Endeavour and the reason was some problems with heating materials. All of us remember the experience of Challenger. . . .However it seems that in the case of Endeavour the phenomenon of groupthink didn¢t occur. . . .

That clearly in my eyes shoes a mentality of learning by mistakes. Personally I think that NASA when it comes to a decision for launching or not is really aware of the phenomenon of heating materials.

The question here is that, based on the previous mistake organizations are aware of the process in which the mistake took place more than previously. Can this lead to tempering with the process?? ? As Deming says tempering probably will make the process worst. OK in case of NASA where we speak about human lives and equipment of billions you need more that 6sigma quality so tempering is difficult to occur because of the tight limits.

Although in real organization I think this happens. At the beginning definitely there will be the need for improvement but if management is obsessed they will face common variation as special. . This could lead in bad decisions that will make the system worse. . . .

Thus a decision that was based on previous mistakes can lead in worse mistakes. Here in my eyes is a good example for why we should be guided by theory.
