Last week I spoke to a guy that works for a multi-billion dollar, publicly traded company that makes the software that runs a health system's daily operations. The software that he sells is used by thousands of health system employees all day, every day. He told me that, in most cases, when selling his product he does not do a demo. No product demo at any point in the process. So the executive team at a health system buys his software and then forces thousands of employees to use it every day (locked into a 5+ year contract) without ever seeing or testing its usability. As I've written many times in the past, this is why most B2B software is awful. Because it can be.
In big enterprise software, good selling is unfortunately still far more important than a good product.
