How is Root Cause Analysis (RCA) related to your Overall Equipment Effectiveness (OEE) and your MTBF?

Every day organisations suffer from asset failure, operations breakdown or human failure cause. That applies to organisations of all maturity levels. What truly sets them apart is their ability to eliminate root failure causes and prevent them from ever happening again.

These disruptive events have an organisation wide effect, reducing them will also affect the whole organisation. Problems related to availability of assets, quality of product or service and performance of the organisation and its employees have a detrimental effect on the Overall Equipment Effectiveness (OEE) and MTBF. It’s by targeting these causes that RCA can have a strong effect on your organisation.

Increasing your OEE has a game changing effect on differentiating yourself on a global market.

We identify 3 main categories of problems:

  1. Special Cause problems: These types of problems are considered statistical anomalies, Asset breakdowns, sudden extreme variance in production output or quality levels. Their anomalous nature makes them hard to predict and can only be controlled by some for form of monitoring like Predictive Maintenance.
  2. Common cause: These types of problems often have a higher frequency of occurrence than Special Cause related issues. Controlling them will often mean having an influence in Quality level and Asset performance. Any organisation claiming an effective RCA process will be found to at least be on the way to controlling this variance. Solutions in this area are to be found in streamlining processes, changeover tactics, Operator care improvement etc.
  3. Catastrophic problems: This category contains all problems that have a catastrophic effect on the organisations business goals. They are often unexpected, Special Cause, but are to be avoided at all means because they may be catastrophic to your organisation. Even without an RCA program you should be containing these, but a structured approach to RCA will increase your chances significantly.

If you recognise your organisations problems in the above, I-care’s RCA solution can help you!
