- Perceived quality (PQ) is one of the most important factors in engineering signoff as well as customer delight and product improvement (feel, look & touch). The PQ is something related to the feel of the product in terms of the gap, flushness, fitment, and appearance as per the customer's perceptions and expectations. Validate both design and engineering with perceived quality review. In today’s automotive bus industry this is equally applicable. In this paper we have explored the dimensional management scope in improving the PQ requirements and expectations by utilising the dimensional variation analysis (DVA) approach. We have explored & explained the fundamentals of the vehicle aggregates fitment process and the impact of fitment tolerances as used in DVA model to resolve vehicle packaging issues (critical gaps & clearance variation as per the expected no. of vehicles to be manufactured in the future at the initial stage of the vehicle design). It is further extended into system-level DFMEA to include DVA in the detection against failure modes related to bus body PQ assessment review.
