4.5 Comparison of the results
Table III shows a comparison of the columns in the normal and proposed FMEAs, as
well as the behavior of the items of influence when completing the FMEA.
A number of factors were observed in this study:
. With the new spreadsheet, which served as an “updated failure history”,
knowledge operated at a company level.
. There was a reduction in the time required to complete the FMEA, resulting in
satisfaction among those involved.
. Supplier-manufacturer involvement was fundamental to improve the quality of
the information and team participation.
. Mastery of the method proved to be fundamental in the analysis.
. The suggestion of using Microsoft Access is only feasible if all those involved
have this application. In practice, Microsoft Excel is more common, making this a
more logical choice. However, macros could be implemented to automate the
procedure.
