What This Unit Covers
Build a rough prototype quickly to answer one specific question.
Write a test plan with a measurable success criterion and run enough trials to trust it.
Analyze a failure to its root cause instead of replacing the broken part and moving on.
Run a design review that surfaces problems while they are still cheap to fix.
Review the sequence and goals here, then resume at your first incomplete lesson.
