Yes and no. There's some utility to having a dogma with a well-defined name. If you wanted to introduce each of these practices separately, you would have to explain each one and get people to buy into each one. Each one is a potential point for argument and derailment. It's convenient to have a handle that refers to the whole kit.
In practice, you'll have to introduce the techniques incrementally, but having an over-arching name can help people see these as part of a unified plan.
I can attest to how easy it is for even a small company to completely disregard any sort of mechanism for learning from mistakes over time. It goes against the grain of human nature to bring up problems in a useful way in a lot of cases I think.
