Why do we need to define terms and definitions?

  • To remove confusion among terms and acronyms
  • To alleviate a long-term problem that interferes with effective communication between analysts and requestors and within the failure-analysis community
  • To provide certain terms, expressions, acronyms, etc. are prevalent in and peculiar to this profession
  • To determine which terms and definitions are focused directly on failure analysis
  • To provide a common language (foundation) that improves communication within the failure-analysis community and between failure analysts and the electronics industry by providing and promoting standardization of descriptive technical language
