When you finish your meeting late, you start late at the next meeting. When this permanently happens, you build up a tsunami of delay. And these are the days when you sacrifice your lunch break to get things done!
The good news: There are ways and methods to finish your meetings on time, including using a meeting timer software with a timeboxing planner and meeting timer tool. You further seed the plant of a better meeting culture and awareness for time and overall productivity of meetings in your organization.
