Who would benefit?

All using pivots for performance metrics

What impact would it make?

Nuanced conversation in metrics is crucial for effective metrics

How should it work?

Replace current option of "average" with other statistical options. For example, if a product group was trying to improve the time it takes an idea to move to an end status, the average does not give a good picture of what most customers went through to have their idea heard. In that example, the median gives a better idea of how long most ideas took to pass through the idea-feature pipeline.
