This document provides an introduction to Just Culture and its key principles. It defines Just Culture as a system of shared accountability where organizations are accountable for the systems they design and how they respond to employee behaviors. It focuses on system design and management of behavioral choices rather than outcomes. The document outlines the three types of human behaviors - human error, at-risk behavior, and reckless behavior. It provides guidance on how organizations should respond to each type through consulting, coaching, or punitive actions depending on the behavior. The goal of Just Culture is to have a fair and just system where human fallibility is acknowledged and the focus is on continuous learning and improvement.
