Root Cause Analysis (RCA)
When Failures Occur — We Find the Cause, Prevent Recurrence & Restore Reliability. Our consultants combine expertise in metallurgy, mechanical engineering, NDT, Lean Six Sigma, and failure analysis to deliver clear, evidence-based findings backed by data, testing, and industry standards.
What Our RCA Consulting Helps You Achieve
- Identify the true technical, process, or human root causes
- Stop repeated failures, breakdowns, and rework
- Improve equipment reliability & production performance
- Reduce scrap, downtime, warranty claims, and customer complaints
- Develop robust corrective & preventive actions (CAPA)
- Strengthen your quality and maintenance systems
- Ensure compliance with ISO, API, ASME, AWS & customer requirements
- Make confident, data-driven decisions
