Reliability Test and Reliability Design

A quality control department is usually responsible for downstream quality problems such as defects and warranty claims. The countermeasures to these quality problems are commonly referred to as "troubleshooting." However, troubleshooting in a company seldom reduces the number of future troubleshooting activities since it doesn't address the root causes of quality problems. Troubleshooting is not efficient in resolving downstream quality problems. To reduce the number of defects or warranty claims, focus engineering resources on upstream design activities to resolve quality issues at early stages of development.
