What you think it means: The ability of some to repeat a word or an idea.

What it means in auto quality: The variation in measurements obtained with one measurement device when used several times by the same person while measuring the identical characteristic on the same product. This means that when using one product, and testing or measuring one item, the result should be the same every time. This ensures the reliability of the product.

This key term is focused on the consumer, not just production. It’s important to realize this because your end user’s happiness and safety is the number one goal.

What you think it means: Things are literally going wrong right now.

What it means in auto quality: this one is actually about the same. The main difference is that it is a term, not just a phrase. The acronym for it is “TGW” and the definition is product attributes or characteristics that produce a negative reaction from customers.
