Drill Deep Root Cause Analysis

Drill Deep Root Cause Analysis is not used to understand what failed but why the system failed
Drill Deep Root Cause Analysis(DDRCA) is a process of investigating and determining the root cause of specific problems with the intention of building and implementing a systematic solution that will prevent a reoccurrence of the problem. DDRCA focuses on underlying issues rather than the specific symptoms of problems, with the consequence that its use to analyze a relatively minor undesirable event that has already occurred can expose previously unrecognized vulnerabilities from which a much more serious problem could arise in the future. DDRCA aims to answer questions such as what went wrong, how it went wrong, and, most importantly, why it went wrong. In addition to identifying unseen operational hazards, DDRCA can also have applications in improving business processes by flagging inadequate or over-zealous control mechanisms.
