Yes - Hypothesis Testing is Needed
If the solution is known, just implement it.
Otherwise DMAIC is a method to determine solutions when unknown. DMAIC uses various tools/techniques to sort out/drill down for potential causes. Then make a hypothesis ("Cause A impacts the result") and use facts/data to validate the cause before implementation. If you don't test your hypothesis the wrong potential solution may be implemented. HOW the hypothesis test is conducted may be a better question. But the idea behind hypothesis testing is valid for all DMAIC projects.
