Interesting observations from all. I would appreciate if the good people that posted on this subject could reveal the item, or product category being tested. It would be interesting to see the "relative relevance" of each test or analysis technique (e.g., MH217, HALT, HASS, ESS, etc) to the product's short and long-term performance.
In my current job, I apply HALT and MTBF calculations to component power supplies. HALT seems to quickly reveal a physical or electronic design weakness. But once (manager-selected) design flaws have been removed, HALT does not seem to predict which component is likely to fail over the power supply's life. I have researched some of my employer's MTBF reports and found most to accurately predict failure modes.
