Speed is visible. Evidence is work in the engine room.
But without evidence, it's impossible to explain why something happened.
In the financial sector, this means: the figures are available – the justification is missing.
When it comes down to it, the „best model“ doesn't win.
But the best traceability.
3 examples where evidence makes a difference:
- AI credit decisions
Documented decision logic: Why was this request rejected? - Forecast deviations in controlling
→ Explainable driver analysis: Which factors caused the deviation? - Invoice approval checks
→ Transparent decision rules: Why was this invoice flagged or approved?
Proof is not paperwork. It is the difference between trust and assumption.
Building up evidence at an early stage saves coordination rounds, escalations and rework later on.
The question is not whether you need proof. It's whether you have it when someone asks.
