Exactly. Also to add it depends on your business model of how you are selling software. Some customers are perfectly fine with MVP and iteration. Others will want everything spelled out beforehand in a contract 3 inches thick. That many times depends on how you are selling your work and what the company you are selling to expects. One place I worked we always shipped MVP. Then would get customers to pay for any new features. New features could be cases 2 and 3 do not work correctly for the customer, however case 1 works just fine for the first customer but they never use 2 and 3. It can come down to how your companies budget works which will drive the business model you have. Now if you are shipping 'boxed' software that mentality could end your product. As instead of a reputation of 'works nicely with the customers' you are 'this junk software is broken out of the box'. It is one of the things I ask during an interview. I want to know what sort of shop it is 'how do you sell your software'. Each are viable methods to make money but some people do not like working that way. I am flexible but I would like to know up front.
