There is a fundamental difference between working on software products vs bespoke software development: In the former you make money from selling the result, in the latter you make money from selling the hours spent creating the thing. If the former is unusable it will lead to bad sales. In the latter it might even lead to additional hours sold in change requests. The former is bought often after evaluation and comparison by the user of the software. The latter is sold to an executive that will never have to use the software as a project.
