A typical manager works 47 hours1 a week. Meetings swallow nearly half that time. Emails eat another quarter. That leaves just 15 hours a week to get actual work done. How much of that time will you spend simply catching up on the backlog of administrative requests awaiting your approval? Probably more than you think.
Managers don't have time for clunky approval processes. They need to make decisions swiftly and get on with their day. It doesn't make sense for them to waste valuable time on administrative tasks instead of moving the needle on the organization's goals.
