Part 3: The 10x Productivity Reality — Where We Speed Up, Where We Slow Down
Prerequisite: Experience managing pull request workflows, familiarity with DORA engineering velocity metrics, cognitive load theory in code reviews, and mutation testing principles. Answer-first: The industry narrative of unconditional 10x developer productivity collapses under empirical code review and cognitive verification bottlenecks. While initial code synthesis accelerates by 800%, review friction and cognitive load escalate by 210% when managing large pull requests. Sustainable engineering velocity requires delivering micro-slices under 200 lines of code with automated mutation testing and strict context window resetting. ...
