Factors to consider in deciding to have a meeting

Decide: Is this meeting necessary?

Are there other ways to have the meeting rather than face-to-face or inperson?

Look at the various communication technologies and systems that you have and weigh up the advantages and disadvantages of each of these compared with an in-person meeting.

Could the meeting simply be replaced by a better reporting system?

A meeting has to be better than playing phone tag.  Email takes time to write and wait for a reply. If the issue is sensitive, then a face-to-face meeting will achieve more than impersonal emails or letters

Meetings can also generate a group energy that cannot be as well achieved with other media.

Can the people who need to be there, be there? Or, conversely, are the people who are invited absolutely necessary to the outcome expected?

Your decision in this regard will affect not only this meeting but also any in the future, because people will expect a repeat of the successfulness of this one.
