Principlev1
Build error detection and quality verification into each
Build error detection and quality verification into each process step rather than inspecting for defects at process completion.
Why This Is a Principle
Derives from Learning occurs when outcomes differ from predictions, (learning occurs when outcomes differ from predictions) and Encoding Depth Determines Retention (encoding depth determines retention). Prescribes when/where to do quality work. Actionable principle, not a specific practice.
