Governance Is the Work
Nobody Wants to Do

Every BI project eventually hits the same wall: two teams with two different numbers for the same metric, each convinced theirs is right. That’s a governance failure, not a data failure.

I’ve built a data dictionary, a certified data program, a reporting repository, and a full Tableau audit across an organisation with seven internal stakeholder groups. None of it was glamorous. All of it was necessary.

And then AI arrived. The moment you start feeding LLMs operational data, every governance gap becomes a liability. This pillar covers how to build the foundation — before you need it.

“LLMs don’t replace BI fundamentals — they make them non-negotiable. Garbage in, garbage out gets a lot more expensive at scale.”

Building a Data Dictionary That Actually Gets Used
Most data dictionaries are written once and forgotten. Here’s how to build one tied to the reporting layer and owned by the people who use it.

Tableau Hygiene: Audit Your Environment Before You Build Anything New
The report graveyard is real. Before adding dashboards, audit what you have — and who’s actually using it.

One Version of Truth: Building a Reporting Repository
A central catalogue of every report, its owner, its source, and its last validated date. Unglamorous. Essential.
