We want to draw the distinction between time management (something individuals either do or not do for their personal schedules) and calendar metrics (something you can read from the aggregated calendar data in your Microsoft Exchange server).
Here we'll start taking a look at some of the global reports you can extract that enable some insight on what your corporation is doing.
Some data we extracted a while ago generated the following results:
Not surprising (to anybody who's worked in an organization with more than fifty people) the number of meetings drops at lunchtime. We interpret this as people wanting to get some private time, but any anthropologist out there will ask how we normalized our results, set up proper controls, and did double-blind studies. None of us are anthropologists. What is more interesting to you the manager are the twin peaks of mid-morning and mid-afternoon for the most popular meeting time. Plan your resource use accordingly.
The outlying time of midnight - 1 AM we think was either security or manufacturing.
Which hour do people meet leads to the question which DAY is favored. In the above report we found that meeting frequency peaks on Tuesday. In LOTS of both legacy and Exchange data we have seen Wednesday and Thursday being the peak, but almost never Monday or Friday.
