Using Six Sigma Quality and Root Cause Analysis Tools

Through the use of Six Sigma Quality and Root Cause Analysis tools, an optimum service level can be reached in your organisation. Six Sigma Quality and Root Cause Analysis tools can identify and fix persistent process errors and quality issues.

Root Cause Analysis (RCA) can help to pinpoint root causes of recurring process issues that affect cost and customer satisfaction levels. Systematic methods through the use of Six Sigma tools such as 8D & 5 Whys should be used to establish root causes of complex process issues. Once the root causes have been established, the core of the problem can be rectified.

Firewall Quality Control Systems strive towards achieving zero PPM (parts per million) quality for customers. Firewalls provide a detailed analysis of all your process Quality Gates (inspection areas), cross referenced with potential faults via Process Failure Mode Effects Analysis (PFMEA) and actual faults found in the process. By identifying potential risks and driving improvements via Poka Yoke and upstream Early Warning Systems, quality problems can be completely eliminated.

Early Warning Systems measure process quality deviations at the source. By detecting a deviation at the source it allows for quicker and easier Root Cause Analysis and resolution. Quality faults identified by the customer are too late and mean that it’s much harder to determine the root cause.

Vative’s vast range of experiences and capabilities allow for the application of quality tools, techniques and methods of Six Sigma across all industries covering projects of all sizes and scope. We have the capacity and capabilities to service all clients across Australia and Asia.


It is important that your team understands:

  • Why quality is important
  • How to define a problem effectively
  • How to use Ishikawa (fishbone) and 5 Why RCA techniques to effective resolve issues as a team
  • How to determine the current Quality risks
  • What a PFMEA is and how to use it to drive improvements
  • What Early Warning Systems are, and how to use this tool to remove Quality risks
  • How to implement effective in-process quality monitoring

Benefits of using Quality tools:

  • Links directly to Continuous Improvement Processes
  • Links directly to Overall Equipment Effectiveness (OEE) and uptime
  • Reduce stock fluctuations

Quality is never an accident, it’s the result of careful execution.
