MEETorDIE takes a humorous approach to a serious issue, how much money is being wasted by large staff meetings.
It's safe to argue that many times meetings aren't the most efficient way to spend the time — and the payroll! — of the people involved but unless you have access to HR records you have no way to even estimate just how much payroll is being wasted. MEETorDIE calculates the amount of payroll wasted based on industry-wide averages, the number of the people in the meeting, and the type of employee they are.
Obviously it's just an estimate (and based on US salary figures) but it's a great way to get people thinking about whether or not a meeting is "worth it" and you might even be able to use it as an interesting talking point with your boss about cutting back on meetings that pull your team away from more productive work.
Have a neat tool for visualising data? Let's hear about it in the comments.
