Root Cause Analysis

Transform a reactive reliability organization into a proactive reliability organization.

What is Root Cause Analysis (RCA) and Why is it Important?

Root Cause Analysis (RCA) is the core skill used by maintenance and reliability engineering professionals to resolve problems that impact an organization’s ability to meet strategic objectives. RCA is not just a tool, it is a systematic methodology used by managers, engineers, supervisors, operators, and technicians to eliminate chronic problems that affect an organization.

Often, root cause analysis is used to conduct bad actor analysis. A bad actor is an asset that can be associated with negative effects such as downtime, maintenance costs, safety, and risk. They are typically associated with frequent unplanned failures and hindered productivity. Proper management of these bad actors includes prioritizing and investigating the root causes of the failures and implementing corrective actions to decrease the chances of them happening again.​

Allied Reliability’s Approach to RCA

Figure 1 shows Allied Reliability’s systematic approach, known as the “R5 Cause Analysis” process. This model resembles the popular Six Sigma DMAIC methodology, whereby you first set out to define the incident to recognize the problem needing to be solved. With a clear understanding of the problem, the initial investigator then measures the impact that the problem is having on organizational objectives to rationalize whether or not further investigation is warranted.

With a ratified path forward, the RCA team proceeds to analyze the causal factors to determine how to improve performance by mitigating the root causes of the incident. Finally, the process is complete once you have realized that your solutions are effective and have implemented controls to prevent recurrence.
