Case Study Regression Analysis

On analysis of the raw data it quite evident that the number of defects after delivery of products greatly declined between the years 2010 to 2014. Defects reduced from an average of 800 million defects in 2010 to 400 million defects in 2014. This represents a fifty percent reduction rate in the number of defects. This can be attributed to various factors which will be discussed below.

It is evident that PLE reengineered products based on supplier production policies. This played a crucial role in reducing the defects since manufacturing now placed infancies on where the product would end up. This ensured that products were properly manufactured according to suppliers demand and as such made robust enough thus reducing defects.

PLE also made a decision to work with suppliers to reduce these defects. Suppliers interact with clientele on as first hand basis and as such receive crucial after sales information that may not be necessarily conveyed to the manufacturer. Good business relationship with the supplier ensures that this critical aftersales information is conveyed to the manufacturer and as such the manufacture is able to improve on production accordingly.

It is evident that had this decision not be made the number of defects would have increased or stagnate at its previous current level.

The current number of defects is still very high despite a 50% decrease. This can be improved in a number of ways. First is to ensure the manufacturer and supplier relationship is maintained and strengthened at all costs. Secondly would be to do an analysis or study as to the exact reason for occurrence of this defects and finally is to improve after sales services to be able to get fist hand information on the defects .
