That's because the "right way" needs to vary depending on what you're building. You don't build a garden shed the same way you build a skyscraper. Likewise, you don't build a twitter client the same way you build an implantable pacemaker.
And for that matter you don’t build a twitter client the same way you built a backend for twitter clients to connect to. In my experience every team and project has a unique way of working and that could be encouraged.
