The difficulty of measuring productivity is particularly felt by senior developers. They save time and effort in ways that are non-obvious, which might be measured by dependencies that were not added, design patterns that were rejected, or processes that they pushed back on. Just like with living things, unchecked growth is unhealthy for an organism but the actions required are difficult to measure. One could start an attempt with a counter-factual narrative, but this does not map cleanly to KPIs.
