The Situation
Based on an in-depth stufy of HP’s most successful divisions, we discovered that as much of 25% of our manufacturing assets were tied up in teacting to quality problems.
Clearly, a bold approach was needed to convince people that a problem existed and to fully engage the entire organization in solving it.
• Accelerated Life Tests
• Real Time Life Tests
• Reliability Growth Tests, Burn-in
• Field Failures
• Engineering change orders
In this presentation, an outline of a cohesive structure for reliability throughout a product’s life cycle is presented including the appropriate location and use of:
• The Over Stress Tests
• Design Reviews
• FMEAs
• Reliability System Analysis
• Overview of most commonly used reliability demonstration techniques
• Discussion of their pros and cons
• Common misconceptions about reliability demonstration
• Alternative techniques
• Conclusions and recommendations
