A critical to quality tree is a very simple and flexible tool to help you identify the needs of the customer, and break those needs down into measurable items. The tree data structure is helpful because it forces us to dissect needs into more granular items that we can structure a project around.
You will find the CTQ Tree helpful if:
- You need a guide to help you through the steps needed to convert the I need/want in customers words to a measure.
- You are involved in a project that initially has many “soft” or qualitative aspects and not enough dimensions that are measurable.
- You need help prioritizing which outcome indicators are important relative to each other.
- You need help identifying what metrics to focus on that would indicate whether the project was a success of not.
The video below will explain the CTQ Tree a little bit more and show you how a critical to quality tree can be both simple and powerful, helping you succeed in your project.
