Knowledge workers attend an astounding number of meetings, many of which aren’t a good use of their time. According to recent research from Microsoft, inefficient meetings are the number one barrier to productivity, with 68% of employees saying they don’t have enough uninterrupted focus time during the workday. Further, research shows that up to one-third of meetings are likely unnecessary. This issue negatively impacts productivity and engagement, with a cost estimate in the hundreds of billions of dollars.
