Mike & Tommy tackle the challenge of kicking off Fabric with a clean slate, exploring how to prevent model fragmentation and build a culture of shared semantic models from day one. They discuss whether to rebuild from scratch or incrementally consolidate, why teams resist reusability, and how to establish governance that encourages collaboration without becoming a bottleneck. The episode delivers practical strategies for defining core business entities, creating a semantic model catalog, and building the organizational discipline needed to maintain a true single source of truth.

Starting out with Power BI, our company's reporting team has been using import mode exclusively and we have not been reusing models very commonly. There is a lot of redundant data storage and I'm sure there are many conflicting DAX definitions and model relationships. I've started learning about Fabric and I'm realizing we will need to rebuild some semantic models from the ground up.

Thing is, I'm not sure our team will have the patience to do things right. I suspect they will dive in and start creating more redundancies and our work will continue to be fragmented. How can I kick things off on the right foot and influence the team culture to work together with a single source of truth rather than individual sources?
