The Three Pillars of Customer Success

I'm a simple person and big believer that almost anything can be broken down into 3 main components. In my opinion, an effective Customer Success plan is no exception. If I were to be asked to create a Customer Success plan today, these are the 3 components (or pillars) I would use as my framework.

1) User Adoption 
2) Satisfaction
3) Retention

What do you folks have to say about this? If you were asked to create a Customer Success plan, would these three pillars be a good place to start? 

Looking forward to hearing your opinions!
