The great thing about having a simple and straightforward way of knowing how much work-time goes into a process, is that if you also know the total amount of work-time available to you, you can easily work out how much spare capacity you have. Or not.
Even better, you can work out exactly how many more instances of a process you can run with that spare capacity. So you can target your sales process at getting the most bang for your buck.
Happy days!
