I’ve long been frustrated that meetings are not quantified, where the cost of the meeting is calculated based on the wages of those in the meeting. With that data, it would be more obvious to determine that cost/benefit of the meeting.
Some back-of-the-envelope calculations here. For four people making an average salary of $100,000 (I’m using programmer gross salaries, including benefits and vacation), a 30-minute meeting would run $96. For twelve people for two hours: $769. Twenty people for two eight-hour days (for example, training): $15,385.
