To improve the way you do meetings in your organization, take some time to review the meeting process occasionally. yoyomeeting provides a way to measure meeting effectiveness, by giving you the option to rate every meeting after your meeting (in a way even strict works councils will approve it).
Anyway, the important part is not the final number of stars your meeting achieves, but the quick reflection about it. What could have been better? What could have been worse? On what part of the process will you have an eye on in the next meeting as meeting host?
