Editor's Notes
Blue – low occurrence variability / durability big issues often based on many confounding issues occurring at the same time Red – 100% occurrence or close to it something gone terribly wrong but low impact; either easy to deal with, fixed or customer accepts Yellow – variation day to day stuff, the stuff our quality systems really exist for; case by case they seem small, but overall impact results in customer satisfaction or dissatisfaction
Objective, Ideal – Loop 2 ‘ should ’ focus on containment and correction. If Loop 2 is the actual quality FILTER, then Loop 3 can focus on being a faster version of Loop 4, meaning a voice of the customer / customer advocate and provides a view into how the customer is receiving the product proactively. Objective, Pragmatic – Often Loop 2 isn ’ t this strong, and Loop 3 must focus more on being reactive rather than proactive. This means trying to catch things in general and dealing with corrective actions from input from Loop 4 and 2. The key here is using the information to develop checks and filters for the right stuff. A filter that tries to catch everything will fail.
