Answer 1

#1. True. The Cause and Effect Matrix relates Process Steps to Process Inputs (X’s) and correlates the Inputs to Process Outputs. In a C&E Matrix, Customer Requirements (or Y’s) are ranked by order of importance to the Customer.

we assign a “priority factor” to each output. We normally use a scale of 1 – 10 with 1 meaning the customer cares little about this and 10 being the customer places ultra high priority to this output.

#2. mistake proofing is associated with poka yoke. Poka-yoke is the act of error proofing a process through great design. A poka-yoke is any mechanism in any process that helps an equipment operator avoid (yokeru) mistakes (poka).

#3. FMEA is a qualitative tool that focuses on how a process, product or service might fail. Failure mode and effects analysis was one of the first highly structured, systematic techniques for failure analysis. FMEA provides only qualitative information .
