Define and Verify Root Cause(s)
A technique used extensively in analytical problem solving is a comparison analysis. This analysis looks at what �is� and what �is not� in the problem description.
Potential causes can be discovered by conducting a survey. By surveying the customer who has witnessed the problem, more potential causes can be highlighted.
Asking �Why� repeatedly is effective in driving the process toward root cause and generating more complete understanding of the cause and effect.
