In the end Puppet and the Puppet modules are just tools. You need them, but they are certainly not enough to get results
Our consultants experienced firsthand what you need to get this kind of change going in large IT organizations. Most of the time, there are good reasons that things are the way they are. Change needs to be applied gradually but surely. Our approach is based on making steps together towards a common, defined goal.
Tools like Puppet and Chef change the dynamics of your change processes. A large change control board that reviews changes is no longer required if the change takes no more than ten minutes to implement. It’s no longer required to collect changes for three months if you’ve build the confidence that IT infrastructure changes are applied easy, consistent and painless.
