1. CTQ Tree Template

The CTQ Tree is a step-by-step guide to break down customer needs into measurable quality requirements and performance metrics.

Level 1: Customer Need

• Identify the core customer or stakeholder requirement.
• Example: “Efficient Order Processing”

Level 2: Quality Drivers

• Pinpoint what drives quality for this need.
• Example for Order Processing:
  • Speed of processing
  • Accuracy of order entry
  • Order tracking visibility
  • Integration with inventory

Level 3: Quality Requirements

• Define measurable requirements for success.
• Example for Speed of Processing:
  • Order entry time
  • Processing time
  • Confirmation time
  • Shipping time

Level 4: Performance Metrics

• Establish specific measurements and targets.
• Example for Order Entry Time:
  • Target: < 2 minutes per order
  • Error rate: < 0.5%
  • System response time: < 1 second
