Based on the diagrams above, in what order should the customer complaints be addressed?

To determine the order in which customer complaints should be addressed, we need to prioritize based on the criticality of issues using factors such as:

Customer Criticality Scale - This is the most important factor since it reflects how severely the issue impacts the customer experience.

Cost to Company - This helps prioritize complaints that are financially significant.

Number of Complaints - This indicates the frequency of the issue but is generally the lowest priority compared to severity and cost.

From the diagram:

Problem Y has the highest customer criticality, so it should be addressed first.

Problem W has the second-highest customer criticality.

Problem Z has high frequency but is lower on the criticality scale than Y and W, so it comes third.

Problem X has low criticality, cost impact, and frequency, making it the lowest priority.

Therefore, the order to address the customer complaints is Y, W, Z, X, making Option C the correct answer.
