The standard is built around three core methods that offer flexibility depending on available data: ALD Reliability Software Method I (Black Box):
Integrates Method I with data obtained from laboratory testing. Method III (Field Data):
Used when no lab or field data is available. It relies on a "parts count" approach using generic failure rate tables. Method II (Laboratory Data):
The most flexible approach, which combines generic rates with actual field tracking data to refine predictions. ALD Reliability Software Enhancements in Issue 3
