What is FMECA ?

FMECA is a well established technique for reliability analysis  The objectives are to -

• understand the failure modes
• identify and rank the critical issues
• through all phases of the life-cycle
• identify mitigating measures
• focus improvements
• deliver implementable results

Proneta uses a systematic approach for FMECA. The steps in the process are -

1. The life-cycle scenario is established, identifying the phases of construction and production;
   
   
2. The baseline system is defined unambiguously for all the phases identified in the scenario, and documented in the form of functional requirements, a schematic diagram identifying all the constituent subsystems and major components and their interconnections, and a process flow for construction (ie installation procedure);
   
   
3. Suitable rankings for Severity and Probability of Occurrence are agreed;
   
   
4. The failure modes of each subsystem in turn are identified;
   
   
5. Each failure mode is systematically explored, using pre-prepared formats, to capture its characteristics in both narrative (with rich content) and ranking.  Those characteristics are –
   1. Cause of failure, probability of occurrence, local and end effects, severity;
      
   2. Links to the supporting documentation (to provide a traceable audit trail);
      
      
6. The FMECA results are analysed to highlight critical failure modes;
   
   
7. For all critical failure modes, appropriate mitigating measures or preventive actions are identified and compiled into an engineering action list.
