RCA is the process of discovering the root causes of problems in order to identify appropriate solutions.
Looking beyond superficial cause and effect, processes or systems failed or caused an issue in the first place
Goals and benefits
1st: To discover the root cause of a problem or event.
2nd: To fully understand how to fix, compensate, or learn from any underlying issues.
3rd: To apply what we learn from this analysis to systematically prevent future issues or to repeat successes.
Analysis is only as good as what we do with that analysis, so 3rd goal of RCA is important.
Instead of a news editor just fixing every single omitted Oxford comma, she will prevent further issues by training her writers to use commas properly in all future assignments.
