I think the challenge with having no process is this: You have to rely on great chemistry and raw talent.

Look at Spotifys videos on their process. Every team is self-driving, because everyone knows how to do stuff. If you work at a company where there is no process, and not every is able to complete the whole task from A-Z, you end up with deadends and people who get stuck. If the culture doesn't encourage knowledgesharing, people end up making crappy solutions.
