Measure delivery throughput and the share of capacity lost to unplanned work.
Throughput per developer week conflates capacity with interruption. Separating focus time shows how much of the shortfall is unplanned work rather than productivity. These figures are useful for capacity planning within a team but not for comparing teams, since story point scales are not shared across them.
Developer Productivity
Throughput = points ÷ developer weeks; focus share = 100 − unplanned − meeting time
