Breakdown

Reading order follows the zones above, top-left to bottom-right.

Designer

Components: What-if parameters, Slicers, Cards, Charts

Hierarchy: Context/control → status/primary answer → explanation/breakdown → detail → next step.

Developer

Interaction: Use only interactions that support the page's next analytical step; typical next level: **Decision / monitoring**.

Navigation: Decision / monitoring

Implementation: Compose from the listed native visuals/controls and the standard interaction patterns in this guide; custom visuals are exceptions.

Common mistakes

Treating the archetype as a rigid screen; adding unrelated analytical tasks; duplicating controls already handled globally.
