We normally calculate ROI in terms of money. For example, for every $1 you spend on a CRM application, you can expect to see a return of $5.60. But what about time?
As a resource, time is a different from money because it’s finite. If you know a particular online advertising campaign is generating good results, you can simply increase your advertising budget for better results. That’s not true of time. Time is a resource you can never get back. Every hour you spend with a lead that never becomes a prospect represents an hour you then can’t spend with more promising leads.
