TABLE OF CONTENTS A tree diagram or perspective chart is a tool that helps a team break an issue into smaller chunks or components. It displays their understanding of the issue and is a road map showing the relationship among the components.
A perspective chart is used for a broadly-defined issue that covers multiple processes or crosses multiple functions. Sometimes teams have difficulty getting a grip on an issue that spans many different processes or is too broadly defined for analysis. The issue can be clarified by drawing a perspective chart. For example, a customer may have defined an issue as "too many late deliveries." The team would break this down further, as shown in the example in Figure A.12.
This tool is used:
When the specific issue or task selected covers multiple processes.
When the specific issue or task selected is too broadly defined to start working on.
When a complex problem or implementation appears and it must be broken into components.
To organize information
In the process management methodology, a perspective chart is most often used:
In Step 3, "Select Issue and Process," to help the team break down the opportunity into manageable components.
In Step 9, "Detail Causes," to group causes and identify over laps.
This tool is fairly flexible in its use. The main thing to understand is that it provides a picture of the different levels and how they interrelate.
