Pardot had a simple architecture with its own database and close alignment with Leads, Contacts, Accounts and Opportunities in Salesforce. This is very simple to understand and the real skillset of a good Pardot Consultant has always been in understanding business problems and processes. They would then create a solution and translate this into the Pardot platform.
Nowadays, it's not as straightforward.
Introducing Marketing Cloud Next aka Marketing Cloud Advanced aka Marketing Cloud On-Core which is built on Data Cloud aka Data360 (Salesforce loves multiple names for products).
Data360 is a CDP (customer data platform) which is not owned by marketing teams, it is owned mostly by Data Analytics or IT teams because of its highly technical, data-driven environment.
So what, Tom?
For marketing teams who have traditional marketing skillsets, MC Next may be a little too technical to manage. Especially because every single automation, including campaigns, are managed in Salesforce Flow.
In Pardot today, a marketer can create a dynamic list and send a campaign.
In MC Next, you need to trust that the Identity Resolution match rates are correct so that the unified profile set up in Data360 is working correctly.
Marketing teams who want to adjust or manage the data will need a level of Data360 (Data Cloud) permission that some companies won't allow.
What I am saying here, is that there's a steep learning curve for B2B marketers and the shape of the team may need to change to align with the technology.
