You are managing an engineering organization that recently changed its release process for digital power-control firmware and embedded software, adding stricter code review gates and a standardized validation checklist before builds move into test. Six weeks after the change, average lead time from code complete to production release increased from 9 days to 13 days, while escaped defects found after release fell from 7.2 per month to 4.1 per month and on-time delivery moved from 82% to 79%. Senior leadership wants to know whether the new process is actually helping the team or just slowing it down, because the next quarter depends on predictable delivery for several customer commitments.
How would you evaluate whether this process change is beneficial overall, and how would you determine if the observed metric shifts reflect a real improvement versus a short-term tradeoff or measurement artifact?
