|---|---|---|---|---|
Purposedifferent | Balanced Scorecard translates strategy into a few interconnected perspectives and metrics. It holds impact, steering, and learning together in daily work instead of narrowing strategy down to financial figures. | When the picture of the problem still needs to become solid, it asks about real situations and consequences. It separates genuine suffering from mere interest in a solution. | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
