Chairing meetings is a profession

A director at a large municipality asked me to chair some meetings in his
place. He would be attending as a participant. He is new on the job and
wants to concentrate on the content, the people and the atmosphere.
Managing the meeting process was my responsibility.
Chairing meetings is a profession. You must ensure that the meeting
achieves its aims and interfere as less as possible with regard to the
content. Managers frequently experience difficulties with this, because
they are often the specialist themselves on the subject. How often
do the most knowledgeable employees, sometimes by lack of growth
opportunities, get promoted to manager?
If specialists become managers this is not always the most favorable
choice. Managers who have a better knowledge of the matter than their
employees, tend to solve the problems themselves instead of facilitating
their colleagues to do so.

Of course, a certain basic knowledge is indispensable to be a good
conversation partner. But being able to listen, being able to make
connections – between people and matters – is a much more useful
quality for a good manager.
Job specialists who chair a meeting often have to bite their tongues not
to interfere with the discussions. With this brand new director it is the
other way around: he appoints someone else to do the managing, thereby
enabling himself to solely focus on the content. I think, this decision
reflects wisdom.
