1. Convert a stakeholder question into scope
The baseline is 21 completed orders and EUR 1190. Region subtotals should reconcile to the grand measures; they do not identify a causal regional effect or an operational target.

2. Integrate SQL/Python analysis with reporting
Completed line value is 119000 cents. Joined row count 42 is not order count 21. An absent month is unavailable; a changed source requires recalculated outputs and updated prose.

3. Write a decision note and defend the limits
The note reports the observed measures, source limits and a specific next evidence request. A suggested eight-point self-review is a learning rubric, not a graded credential or career guarantee.
