When I started as a sales rep at Air2Web, being a salesperson with a fairly technical background, I immediately asked for a login into the software so I could start playing around and learning the software. My boss told me that I would not receive, nor would I EVER receive a login into our software.
His reasoning? If I started to go into the software, I would focus on HOW the software could do certain things and IF the software could do certain things in a certain way – rather than focusing my sales activities on finding the right customers and identifying their pain.
