Piugh Concept Selection Method And Pugh Concept Selection Method

Pugh concept selection method:
Pugh concept selection chart is a decision matrix method that predominantly used for concept selection purpose. Concept selection is a quantitative approach for making decision and used for comparing multiple concepts with respect to a reference or datum concept and determine the given concept better, poorer or equivalent as of their reference concept. AS we know that individuals excels in creating ideas where as a small group excels in selecting ideas.Hence, the concept selection is usually carried by design team after several rounds of scrutinizing and deliberation. The multiple concepts for a specific design is submitted for the pugh method should have passed through the absolute filters.

Subsequently the list of criteria are merged, discussed and prioritized. We can also reduce the criteria mentioned in QFD to 15 to 20 items and then add important factors such as patent coverage, technical risks and manufactuarability. It is also necessary that each criteria should be able to differentiate among concepts properly. The criterias which are satisfying every design concept will not help to select the final concepts, hence should be avoided even if they seem to be very vital.Again the determination of relative weights for each criterion need to be avoided as they adds degree of details which may not be justified at concept level of information. Most preferably the criteria should be arranged in a decreasing order of
