When one micro manages something they control every aspect of it to that point that nothing can go wrong conceivably be out of place. This is great for the manager doing the micro-managing but is it effective given the loss of any kind of freedom and self expression by the employees that are subjugated to this? There are also probably few, if any, performance benefits to this style of management. The loss of initiative may also create a latent performance bottleneck when deliverables cannot be met by specified dates! So go BAC, where micro-management is king!
be more specific. give us some examples you are experiencing.
