The introduction of Puppet on an infrastructure is a long and intriguing voyage without return. It requires planning, patience, method, experience, and skills, but it brings great results.

There's definitively no unique way to face it. In this chapter, we have exposed the general scenarios we might face, the possible alternative approaches, and have suggested a step-by-step procedure articulated on different phases: information gathering, priority setting, decision making, code development, testing, and rollout to production.

These phases should be reiterated at each step with emphasis on what matters to make things done.

We have also faced the changes that such a process involves; how we need a new mindset and new processes to sustain a Puppet setup.

Complementary to this is an effective management of our code: how it's versioned, reviewed, tested, and maintained. These are some of the topics we are going to see in the next chapter.
