Also the devs who write the software never actually need to use it. Developer tools such as editors and compilers are of high quality (relatively, of course) because developers use these tools while working on said tools. Many developers doing enterprise software don't even have a rudimentary idea of the work flow around the app that they're developing. Consequently, they are unable to design an effective and efficient app.
