Free poster
How one number travels from source system to decision: who decides what it means, and where the Data Tax gets paid when nobody does. One page that ties the two books and the free guide together.

How to read it
01
where the number is built
Your existing warehouse stays as it is. Declared grain, reconciliation to the ledger and CI on definitions make each number correct. Correct is not the same as agreed.

02
where its meaning is decided
Owners decide what each rule means; the head of data convenes and does not vote. Every figure passes through a semantic layer with an owner, a record and a test, and comes back with its basis or a designed “can’t answer”.

03
where it gets used, or argued over
With the gate, every dashboard, finance pack and AI assistant calls one definition and the business decides once. Without it, every tool carries its own rule, the numbers don’t match and the Data Tax is paid in checking and rebuilding.

The orange “Cause” tags
Each tag on the poster sits where that cause is fixed. One is an engineering fix in the stack. The other four need a decision at the gate.
