Subject: Calculated Failure Rate vs. Field Failure Rate
Hello, I performed a reliability prediction based on TR-332, and the failure rate looks high. We believe that the real failure rate should be better. Since the product is brand-new, no field data available yet. Is there a ratio of calculated failure rate to field one? Or are there any references addressed this issue? BTW, the product is a telecomunication switch used in central office. Thanks in advance! Steve
