Those of us that have read the book, attended and attained certification, practiced and had experienced colleagues to learn from, or maybe even going on your own on implementing a data vault; may be challenged by old world views for enterprise data warehouses-whether it be dimensional marts (Kimball) or a data factory (Inmon).
Imagine the business have signed the proverbial cheque and the heads of data and analytics have signed up for implementing an enterprise data warehouse as a data vault 2.0 and now you're up against seasoned data warehouse professionals (20-30+ years experience) with battle scars from previous implementations, legacy systems and migrations.
What is your approach to convince the skeptical that this time it will be different?
This time we are not building a legacy data warehouse.
And... were you successful? If not what do you think you could have done differently?
