Email is NOT a meeting!
Some people use e-mail to “discuss” issues and gain opinions. Each time an opinion question is sent to numerous people or to a group list, the e-mails tend to develop branches: the opinions multiply exponentially, the threads take on different paths, and each recipient is now receives multiple strings of the same subject e-mail that have gone in different directions. It all results in spending much more collective time than a one time meeting or teleconference may have taken. This makes it more difficult for participants to see the big picture and the overall opinions. The multiple threads are confusing and time consuming.
Instead of using e-mail this way, it is much more effective and productive to call a meeting and discuss the issue in detail. Invoke the “two-round rule:” when you see e-mails developing circling back the second time, call a meeting to discuss the issue in further detail and put an end to future lack of productivity caused by all those e-mails. Better yet, call the meeting in the first place.
