|When to Use||Purpose|
|Pre-project||Assist in project identification by linking key drivers of customer satisfaction to processes. You can use a CT tree as an input in the Project Prioritization Matrix.|
|Start of project||Improve team and management commitment to the project by showing the links between the project and the customer (can be external or internal), highlighting how the customer will benefit as a result of the project.|
No data requirements exist because you only use this tool to collect and organize data.
