This would seem to be a good strategy!
Hope it helps.

I'm not sure the direct translation of "superposición" works, but this might.

The word "superposition" is one of the worst examples of management jargon I´ve seen for years. It appears to be being used by some organizational management theorists to describe the dominance of particular functions i.e. control functions or information functions in the design and functioning of organisations. In the context here, I believe the source text is using this fashionable jargon (taken from quantum physics) to describe a very old phenomenon, which is what used to be known as the "command and control" style of management, which means the detailed supervision at task level of all activity, and people. Which is exactly the opposite of the management by objectives approach which is implied in your extract from the text. This is where you make people accountable for the objectives and let them get on with it.

"Superposición" looks as though it ought to mean the same as "imposition" here (ie. don't manage the business is a dictatorial manner), but in principle it doesn't mean that and I can't find any instances of "superposición" being used in that sense in relation to business managemente. On the contrary, it is used in the sense that the literal meaning would suggest: overlap or duplication or management functions, which is inefficient, costly and causes disruption through contradictions.

I have tried and, so far, failed to find any evidence that "superposición", in the context of business management, can mean imposition, enforcement, micromanagement or indeed any other style of management. All I can find is "superposición de funciones", ie., duplication or overlap, and in that sense it is fairly common. I think we'd need some evidence in order to conclude that it means something else here.
