In addition to standard and readily available office tools, there are a number of specialist tools that have been developed to aid the FMECA
engineer.
Why use a Dedicated Tool?
FMECAs can be (and often are) developed using a simple spreadsheet office tool. This is probably fine for a simplistic analysis. However, this
approach is likely to be time consuming and error prone for a more complex and detailed analysis. A dedicated tool is likely to have the following
advantages over a simple spreadsheet:
- Automated calculations – Many of the calculations (particularly for criticality) can be performed automatically.
- Automated Failure Mode ‘roll up’ – In a hierarchical FMECA, Failure effects become failure modes at the next level of indenture, a process
which is normally automated within a dedicated tool.
- Consistent failure mode and effect phrases – A dedicated tool often simplifies this process by providing a ‘phrases file’ and ‘drop down’ phrase selections.
How to choose a FMECA Tool
The choice of dedicated tool is subject to considerable debate and is often a matter of opinion. The tool should however be applicable for its use
and the environment. The following list of pointers should help the decision making process when comparing tools from the various vendors:
- The tool should incorporate the necessary functionality and characteristics.
- The tool should be as usable and controllable as possible.
It should also be noted that availability, purchase cost and support costs will also influence this decision making process.
