Question
Answer the following:
A manufacture is making an analysis to find which Paint defects are seen most and which ones need to be worked on and reduced. The following table provide what found: By Using the 80/20 rule, which items should be worked on first? Now evaluate the cost as the driving issue not frequency. If dirt in the paint costs $10 per occurrence to correct. Sag cost $100 per occurrence and Orange Peel costs $100 per occurrence, re-order the items to show which one you would work on first, second and third and create a new Pareto Chart showing your results.Explanation / Answer
Part (1)
The table below gives the paint defects arranged in the descending order of their frequency and other related computations:

So, by 80/20 rule, Dirt on Paint, Sag and Orange Peel should be worked on first in the given order. ANSWER
Part (b)
Incorporating the cost factor, the listing in descending order of total cost would be as follows.
