Final answer:
The subject of this question is Root Cause Analysis, which is an engineering technique for diagnosing the technical cause of failures using previous failures. It involves gathering information, conducting investigations, and finding the underlying reasons for problems.
Step-by-step explanation:
The subject of this question is Root Cause Analysis. Root cause analysis is an engineering technique used to diagnose the technical cause of failures by analyzing previous failures and identifying the underlying reasons behind them. This analysis helps in understanding the root cause of a problem and addressing it effectively to prevent future failures.
It involves gathering information from various sources, such as customers and stakeholders, and conducting a thorough investigation to identify the real problem. Experts often have prior knowledge and experience that aids in identifying potential mistakes and taking a closer look. Root cause analysis is an essential tool in engineering to improve the reliability and performance of systems.
