Turtle Diagram
Updated 2026-08-11
INTRODUCTION
English translation pending.
CORE DEFINITION
The turtle diagram is a process-analysis tool shaped like a turtle: the head carries process inputs and the tail process outputs, while the four legs hold people, equipment, methods, and indicators. As a scaffold it gives a complete review of a process's elements, organizing six key factors in one image so that a process can be analyzed and audited at a glance.
SCAFFOLDING EFFECT
Reduce cognitive load
- Six-part scan: check head, tail, and all four legs before calling a process understood. - Leg fill: answer who does it, with what, how, and what is measured. - Audit trail: use the diagram to expose any leg that is missing or vague.
Anchor fast decisions
The turtle shape organizes six elements of one process: head for input, tail for output, and legs for who, with what, how, and what is measured. It converts the process from a black box into controllable elements, which makes analysis, audit, and improvement possible.
