DevOps – not an easy thing to do: A lot of energy, courage and commitment is needed to execute a cultural change of this kind. DevOps requires a collaborative corporate culture in which teamwork, learning and decentralized decision-making are encouraged. So the cultural aspect of DevOps plays the most key role of all: Optimized technical solutions can only develop out of cultural change, and for that you first have to get the people on board.
That is why the order of importance must always be: 1. People, 2. Processes, 3. Tools.
