Do we instruct or get consensus to get things done

There is an entire spectrum on how to make decisions available to the Manager. One end of the spectrum is highly Democratic – Gather the Team, lay out the options and take a vote – High buy-in, low control.

The other end is highly Autocratic – The Manager simply announces (“Now here this…”), either verbally or in writing, a new policy – High control, low buy-in.

A good way to drive a measure of buy-in and maintain control is to solicit inputs from the Team, but reserve the decision to yourself.
What do you think? The first options can never be executed properly...but many have chose that way.
