    FMEA – Failure Mode and Effects Analysis is an easy to use and yet powerful pro-active engineering quality method that helps you to identify and counter weak points in the early conception phase of products and processes. The structured approach makes it easy to use and even for non-specialist a valuable tool. The benefits obtained encompass by large the investments in time and resources to execute the analysis. A procedure and tools that help to identify every possible failure mode of a process or product, to determine its effect on other sub-items and on the required function of the product or process. The FMEA is also used to rank & prioritize the possible causes of failures as well as develop and implement preventative actions, with responsible persons assigned to carry out these actions.Failure modes and effects analysis (FMEA) is a disciplined approach used to identify possible failures of a product or service and then determine the frequency and impact of the failure.

    Zeeshan,
    Depending on your perspective, FMEA is either a Quality or a Reliability tool. In a design system / component FMEA, the occurence index is an assessment of the likelihood of the failure mode/cause happening over product “life”. In this regard , the information that flows into this particular column comes from life cycle testing (accellerated or otherwise). You are taking the worst case probability (lower limit) and converting it to a simple number in the range 1 to 10. To understand what these number indices mean in terms of dropout rates, consult AIAGs FMEA manual 3rd ed.
    It becomes a quality tool when you are confined to 0-mileage failures or items that can be tracked within the warranty period. This situation fits mfg. and asm. processes quite well.
    In the words of Philip Cosby :”Quality is 100% conformance to requirements”. Reliability personnel have expanded on this by saying that “Reliability is the useful life of Quality”.
    The task you have is daunting. There are however many good references out there to assist you.
    I am going to forward you an example from the medical industry that was developed in a class I instructded at Indiana University @ South Bend. It will show you how the FMEA is integrated into the APQP process along with the inputs and outputs of the FMEA process. This should give you a good start.
