What are the hallmarks of a best-in-class execution and implementation of a CDP?

Using the full range of offerings: Data Management, Recommendations (Models/Scoring), and Activations (Salesforce, Marketo, etc.)
Having very clear process in place already (or in progress)
Having a team that is able to manage, analyze, are savvy, and can make adjustments based on tests and experience
Have very clear initiative and goals that a CDP can help with vs. please just fix my messed up data (until it gets messed up again)
