But only if they are great.
I love a good half-day meeting.
If done right, it means business, it means direction and the measurement is simple.
Were these 3 or 4 hours more valuable than a bunch of 1-hour meetings spread throughout the week?
When done right, they should be.
When done wrong, they will be seen as a waste of time that got you nowhere.
The key to a great half-day session is to only invite those people that need to be there, smaller meetings can stand to waste time, and they can just schedule another small meeting in between lunch and a break.
But a good half-day meeting? You don’t get another shot at making it great.
