Moving from one design system to another is hard to justify without data. Scorecards give you a way to measure the current state before the move and track real progress after, making [[Implementing a design system]] legible to the people who need to approve or sustain it. Without measurement, migration conversations stay abstract and the effort stays invisible, which is the same problem [[Design debt as a performance indicator]] solves by making accumulated debt a metric rather than a feeling.
The risk is treating the scorecard as the goal rather than the proxy. What matters is whether the system works better after the move, not whether the number improved. A scorecard showing adoption without showing reduced friction is measuring compliance, not change.
