Root Cause Analysis
Stop treating repeat failures as isolated events. Allied Reliability uses a structured root cause analysis (RCA) process to help maintenance and reliability teams identify chronic asset issues, understand why they recur, and implement corrective actions that prevent recurrence.
Solve Problems at the Source
Root cause analysis is a systematic methodology used by managers, engineers, supervisors, operators, and technicians to eliminate chronic problems that affect safety, production, quality, maintenance cost, and asset performance. RCA is especially valuable in bad actor programs, where a piece of equipment or system shows a pattern of unplanned downtime, high cost, frequent work orders, or elevated operational risk.
Effective RCA looks beyond the failed component. It identifies contributing factors, establishes a timeline, uses data analysis and proven analysis tools, and separates symptoms from the true root causes so improvement efforts lead to corrective actions that prevent future failures.

HOW IT WORKS
From Root Cause to Lasting Improvement
Allied Reliability begins by defining the problem in business and operational terms, then determines whether the issue warrants deeper investigation based on impact. The RCA team analyzes evidence, evaluates causal factors, develops corrective actions, and confirms whether solutions are effective enough to prevent recurrence.
1
Define the Problem
Define the incident, asset, failure pattern, and operational impact.
2
Assess the Impact
Measure downtime, cost, safety exposure, quality impact, and other business consequences.
3
Plan the Investigation
Confirm the investigation scope, team members, evidence requirements, and decision criteria.
4
Determine Root Causes
Analyze causes using work history, interviews, observations, data, and structured RCA tools.
5
Implement Corrective Actions
Select corrective actions that address true root causes and contributing factors.
6
Verify Lasting Results
Verify implementation, measure effectiveness, and establish controls to sustain the improvement.
our approach
A Structured RCA Methodology
Allied Reliability uses a systematic approach known as R5 Cause Analysis. The model resembles the discipline of DMAIC in that it begins with a clear problem definition, quantifies impact, and moves through analysis, corrective action, and verification. The goal is not to complete a form; it is to improve performance by mitigating the causes that allowed the incident to occur.
Recognize the problem and define what happened in clear, objective terms
Resolve the causal factors through practical corrective actions that address root causes.
Rationalize the need for RCA by measuring the effect on strategic objectives
Realize the benefits by confirming the actions worked and adding controls to prevent recurrence.
Ratify the investigation plan, so the team has authority, scope, and required evidence.
Solutions
Where Root Cause Analysis Creates Business Value
RCA helps reliability teams prioritize and solve the problems that consume time, budget, and production capacity.
Reduce Repeat Equipment Failures
RCA identifies why failures keep returning and what needs to change in design, operation, maintenance, materials, or procedures.
Strengthen Bad Actor Programs
Work order and downtime data can identify the chronic assets driving emergency work, maintenance cost, and lost availability.
Improve Maintenance and Operations Practices
Investigations often uncover gaps in procedures, training, standards, lubrication, inspection quality, or operating conditions.
Prevent Recurrence With Corrective Actions
Corrective actions are tied to validated root causes, assigned ownership, and follow-up controls rather than generic recommendations.

FAQs
Frequently Asked Questions About RCA
When should we perform a root cause analysis?
RCA is appropriate when a failure or event has meaningful safety, production, quality, cost, environmental, or customer impact, or when the same issue keeps recurring despite repairs.
What information is needed for an RCA?
Useful inputs include work orders, downtime history, maintenance records, operating data, inspection results, photos, parts history, procedures, interviews, and any evidence from the event.
How is RCA different from troubleshooting?
Troubleshooting restores function. RCA determines why the problem occurred and what must change to prevent recurrence.
Who should participate in an RCA?
The best RCA teams usually include maintenance, operations, reliability, engineering, supervision, and people closest to the work. The right team depends on the failure and operating context.
What deliverables should we expect?
Typical deliverables include a problem statement, timeline, evidence summary, causal analysis, validated root causes, corrective actions, owners, due dates, and follow-up controls.
Can RCA be used with a bad actor program?
Yes. RCA is often used to investigate bad actors after data analysis identifies assets with patterns of downtime, cost, repeat failures, or risk.
