Frequently Asked Questions
What is the 5W2H framework in 8D?
5W2H stands for Who, What, Where, When, Why, How, and How Many. It creates a precise, data-driven problem statement that eliminates ambiguity in D2....
What is Is/Is-Not analysis?
Is/Is-Not analysis compares what the problem IS to what it IS NOT. This contrast immediately narrows investigation scope by ruling out unaffected variables....
Why is D2 critical for 8D success?
A well-stated problem in D2 can reduce D4 root cause investigation time by up to 80%. The precision of D2 directly determines the speed of D4....
