Diagnosis

Diagnosis (from ancient Greek διάγνωσις = discernment) is the identification of the nature and cause of anything. Diagnosis is used in many different disciplines with variations in the use of logics, analytics, and experience to determine the cause and effect relationships. In systems engineering and computer science, diagnosis is typically used to determine the causes of symptoms, mitigations for problems, and solutions to issues.
