This course introduces error proofing—also known as poka-yoke—as a method for preventing mistakes before they result in defects. You’ll learn how simple design features, visual cues, and automated checks can be used to reduce human error, improve safety, and enhance quality.

Error proofing plays a critical role in building reliable systems, especially where repeatability and compliance are essential. This course covers practical strategies that can be applied in production, assembly, and administrative processes.

After completing this course, you will be able to:

• Understand the purpose and impact of error proofing
• Identify different types of error proofing methods
• Use error proofing to prevent or detect mistakes early
• Design simple and effective error proofing solutions
• Apply error proofing in physical and information workflows
