How to use it

Identify the customer requirements: Begin by understanding the needs and expectations of your customers. This could involve conducting surveys, interviews, or analyzing feedback.
Create a CTQ Tree template: Draw a hierarchical tree structure with three main levels - customer needs at the top, product features in the middle, and process requirements at the bottom.
Map out the relationship: Connect the customer needs to the corresponding product features and process requirements. This visual mapping will help you see how each element is linked.
Identify critical quality characteristics: Determine which product features and process requirements are critical to meeting customer requirements. These are the key quality characteristics that must be prioritized.
Focus on prioritization: Use the hierarchical structure of the CTQ Tree to prioritize and focus on the aspects that have the most significant impact on quality. This will help in aligning processes with customer expectations.
