"My office is two kilometers away, and on foot the trip takes about twenty-five minutes, sometimes a bit more, sometimes less. Like most locals, I eventually switched to a bike, and the commute dropped to around 6.5 minutes. Later, I found a shorter route without bridges or traffic lights; my commute dropped down to about 4.8 minutes. If you plot these trips over time, you get a picture like this:"
"Each flat section, or plateau, represents a stable process (walking, biking, new route). Real improvements appear as clear, sudden drops to a new, faster level. Each flat section represents a stable process, walking, biking, new route, with its own average and some natural variation around it. Even when nothing changes, no two trips take exactly the same amount of time. That variation is just noise: wind, red lights"
Combining DORA metrics with Process Behavior Charts (PBCs) enables engineering teams to separate normal process variation from meaningful signals. PBCs reveal unusual spikes and early signs of delivery degradation caused by broken tooling, unstable environments, onboarding challenges, or human factors. DORA metrics become instruments for validating hypotheses about practices such as pair programming, team scaling, and tooling changes rather than mere reporting KPIs. Long-term DORA data exposes systemic performance plateaus and shifts, helping connect improvements to architectural, cultural, and process changes. DORA metrics cover only the delivery portion of the value stream, so pairing them with product metrics and well-being indicators yields a more complete picture of performance and impact.
