I agree that micromanagement is a control issue.   All the above suggestions are great but unfortunately not all bosses or managers have an interest in giving up that control.   And even with demonstrating great performance, accountability and support of the manager some will not change behaviors because of their own issues or lack of understanding of empowerment.

Having said all that, in order to overcome this challenge, it needs to be a top-down driven culture change.   If a manager has senior leadership trust them, and empower them, to make decisions (even if sometimes they are wrong) they will be more likely to pass that trust down to their subordinates.

Cultures are difficult to change but with good leadership at the top and a well thought out strategy, it can be done.
