More importantly, how does your boss know? And what about your clients/members/stakeholders - how do they know?
Research shows that meeting consumes more time than any other business practice: people meet all the time. And what are they getting for this investment? Research also shows that by and large, people find many meetings a waste of time - so obviously they're not getting much out of these meetings that they recognize as valuable.
This ridiculous state of affairs shows no signs of shifting, despite very clear, readily available, and consistent information about how to make meetings work. We KNOW that meetings are important to getting work done and moving projects forward, because there isn't any way to more effectively get the buy in from a group of people. We KNOW that meetings are more enjoyable, more productive, and get higher ratings from everyone involved when they have an agenda, stay focused, and have documented results.
We KNOW all of this, but we rarely put these techniques into practice. Most business meetings today have no clear work product. Some people spend up to 80% of their work time in meetings, the majority of which they end up with nothing to show for it: absolutely nothing they can point to, revisit, or pass on to a colleague. Forgettable, at best.
Admittedly, some people don't have any experience or training in basic meeting skills. For everyone else, though, what's the problem? Why is this not only accepted, but the norm?
