Root Cause Analysis

We now begin our journey with answering the why question from all the insights we have gathered till now. Let's assimilate all our results that we have validated in our EDA exercise. Once we have all the results, let's try to simplify it to create a simple story that helps us in answering the questions in a more lucid way.

The following figure is an extended version of the DDH matrix we designed in the previous section along with the results we found during our exercise:

Hypothesis	Result	Insight
Line 1 has an overall higher chance of manufacturing more number of bad quality detergent products	FALSE	Assembly Line has no impact on the end quality of the detergent
Line 1 has an overall higher chance of deteriorating the Output Quality Parameters in the detergent	TRUE	Assembly line has an impact on Output Quality Parameter 2,3, and 4
As the deviation between Order Quantity and actual Produced Quantity increases, the chance of the bad quality detergent...
