It's a transformation

The change of focus from accessibility to dependability is a business transformation, and like any transformation it is going to take some time.

It needs good planning, with a clear long term vision.

It needs good communication, particularly with those stakeholders who you may be asking to do more work (upstream data producers) because the overall cost to the business is lower and the outcomes are greater.

And it needs to be supported with the right tooling. You’ll need a data platform that has been designed to support this way of working, and one that your stakeholders will choose to use.
