Listen. I've spent far too many of my working years dealing with companies that have caught religion of some sort. It doesn't matter which one it is, be it ISO, CMMI, Six Sigma or some virulent form of agile (yes SCRUM people, I'm talking to you); its a religion. Instead of focusing on the business and developing sound processes that fit the business model and the company culture these companies put in place this huge infrastructure hoping that this will make them automatically successful.
It does kill whatever passion there is though. Yes that goes for agile too but in other parts of the company than the one you might be sitting in.
These days I have a good rule that works - when a company tries to sell me services based on being CMMI level 5 I tell them to far, far away and preferably perform some acts that are illegal in several states. After having dealt with a couple of them I have realized that the only genuine thing generated is a huge paper trail and innovation is dead or dying.
As to your question - I don't know and I don't care. I can only make the friendly suggestion that you look for work in a place that doesn't focus on religious adherence to principles defined elsewhere. I promise you that it'll be more fun, challenging and ultimately interesting.
