When you're trying to improve quality and productivity, it's essential to target the right problems, get the right people involved in solving them, and make sure the solutions work. CEDAC will help you do all three. CEDAC, or Cause-and-Effect Diagram with the Addition of Cards, is a modification of the "fishbone diagram," a standard QC tool. One of the most powerful, yet simple problem solving methods to come out of Japan (Fukuda won a Deming Prize for developing it), CEDAC actually encompasses a whole cluster of tools for continuous systematic improvement.
"The process is great and will be an effective way to bring continuous improvement to our company.It puts problem solving into a systematic framework."
