QUALITY IMPROVEMENT

PRAESTAR CONSULTING CAN HELP ELIMINATE UNRESOLVED QUALITY PROBLEMS AND REDUCE WARRANTY COSTS

Case Study

Who: A Leading Automotive Manufacturer with Global Operations

Problem: The firm experienced abnormally high warranty costs across all product families. They also experienced increased customer dissatisfaction with repeat-occurences of the same failure mode.

Solution: Praestar Consulting analyzed warranty data and found that problems, when detected, were not adequately solved due to failed identification of root cause(s). Praestar Consulting developed Root Cause Analysis training, facilitated solving sessions (including Fault Tree, ishikawa, and five-why analysis), and helped develop “killer tests” to verify problem resolution. Training and consulting was delivered around the world by Praestar staff to all engineering, quality, and production engineering staff members.

Benefits: Measured customer satisfaction showed strong increases. Warranty costs were significantly reduced along with repeat-claims. The training program delivered by Praestar resulted in sustained quality improvement.
