DISCUSSION BOARD REPLY al Affiliation) mate thread on Taguchi Method The mate found the method Taguchi developed to be interesting in that he challenged the traditional approach in design of experiment by claiming that the design stage is where the most of the quality of products and services is determined. The main advantage of the method as brought out by the classmate in discussion is worth considered as it emphasizes on the mean performance characteristic values, which are close to the target instead of a value that is within specified limits. This makes the method improve the quality of product.
The method hence becomes easy to apply in most engineering situations (Wu & Wu, 2000). There are disadvantages of Taguchi method that were not considered by the classmate in giving out views. The main disadvantage of the method; results obtained are only considered relative and do not indicate exactly show the parameters that has the highest effect on the performance characteristic value was not considered by the classmate. The method that was chosen also does not test all the combinations that the variables have due to orthogonal values.
The method has also been seen to have a limitation of being offline and this makes it inappropriate for the processes that are always changing such as simulation studies (Harris, 2008). The difficulty that was brought about by the classmate was right as Taguchi methods have been criticized by users in literature difficulty that it has on accounting for interaction between the parameters. The method mainly focuses on designing quality rather that making correction on qualities that are poor. This makes them applied at early stages of development processes (Bendell, 2009).
The hybrid approach provided the decision makers with the risks and benefits associated with selecting a supplier. The risk and benefit factors are then analyzed to determine relative importance and are used to compute a score. ReferencesBendell, T. (2009). Taguchi methods.
