Turtle Diagram

The Turtle Model, also known as the Turtle Diagram, is a tool from quality management used to visualize processes and illustrate relationships with the goal of identifying risks and improvement opportunities through analysis. The process is depicted as a turtle, with each part representing a process element. The head represents the input and the tail represents the output, while the legs serve as process supports. Details about material resources (What?), key performance indicators (Which?), work content (How?), and involved personnel (With whom?) are captured using W-questions. This allows for the identification of risks, which are located under the turtle, and the subsequent development of possible countermeasures.
