Six Sigma DMAIC Process - Analyze Phase - Why Analysis

Why Analysis is explained through the below example:
  • Why does the home-finance loan application process take more than 10 working days to reach a “creditworthy” decision? Because many applications, especially those received by post, have unclear or blank fields.
  • Why do we have applications that have blank fields? Because the customer did not fill out the details.
  • Why did the customer not fill in the details? Because the instructions were unclear.
  • Why were the instructions unclear to the customer? Because the directions were not understood.
  • Why were the directions not understood? Because many customers had not read them.
  • Why had they not read them? Because the print was too small. This chain is an example to investigate: verify each proposed cause with evidence before choosing a remedy.
