Mathematical Equations
Mathematics is the key to understanding the intricate connections that govern many systems. Often times these systems break or mislead analysts, but by returning to mathematics we can balance, redefine, or redetermine the most accurate relationship at work. Here is just a sample of the mathematical relationships I have invented.

Customer Satisfaction Rating
The overall weighted average of customer satisfaction for the entire year. The weight is aimed towards capturing the disappointment a customer receives when they are unable to buy their product for the entire week.
Total Loss Ratio
Total Loss is a ratio that can be used to give a quick report of how well a product is doing. For this study all pivotal products will have low TLR ratings. TLR will incorporate a combination of customer satisfaction rating and a rating that depicts how much profit was lost to no product.
No Product Downtime
No Product Downtime is the percentage of time a product is not available for purchase. A Z-Score was calculated in the background and averaged with neighboring weekly Z-Score sales, then a threshold was placed on what Z-Score value would flag a product. NPD will add the number of times an item flagged as no product and divide it by the total number of weeks in this study.
