Is stable process good?
During my PMI e-learning, it was pointed out that to improve your business you have to try make all processes in the company to become sustainable. But, than if in the process variation there aren’t any special or assignable causes, how we will know what to improve in our business? There won’t be any stimulus or indicators that process should be improved.
For example, I can consider a challenge in my life either as a problem, or as opportunity to change something and make it better. In terms of variation, assignable causes also can be treated as an opportunity not as problems that we have to solve! Maybe companies shouldn’t push themselves to achieve sustainability, because sustainability can be converted to stagnation? And maybe it would be better to have your variation unsustainable, which can support your further improvement???
