This module introduces you to another powerful and effective Lean tool, poka-yoke, which was developed as a key component of the Toyota Production System (TPS). Poka-yoke is a process improvement technique, literally meaning “avoiding mistakes or errors.” It was developed in the 1960s by Shigeo Shingo. This technique significantly decreases the number of defects produced and is also known as error-proofing. In this module, you will learn about some real-life examples of poka-yoke and how to implement this technique by eliminating opportunities for defects or errors.

In this module, you will learn about the concept of the eight wastes or 8 forms of waste, which is a fundamental Lean manufacturing and Six Sigma principle. The various non-value-added activities and inefficiencies within a process are known as the eight types of waste. Finding and reducing or eliminating these wastes can cut down your organization’s costs, chances of accidents, and lead times and make both employees and end customers happier. Waste reduction is a fundamental concept in Lean Six Sigma, and this module will equip you with the knowledge and tools needed to improve efficiency, productivity, and quality within your process and organization.

In this module, you will gain an overview of control charts and their application in process monitoring and quality control. Control charts determine if a process is in control or is stable or if it is out of control and requires some adjustment. Control charts are beneficial for your organization as you need to take some action to correct the variations that could have a negative impact on your business. You will learn about specific control charts for continuous data and how to create and interpret these charts, analyze patterns, and make data-driven decisions to improve process stability and performance. The module combines theoretical knowledge with practical exercises and case studies to equip you with the skills to implement control charts in various industries.

In this module, you will work on a peer-review assignment, which is based on the concepts taught in the Improvement Techniques and Control Tools course. In this assignment, you will apply your knowledge about Poka-Yoke to identify how various Poka-Yoke techniques are used in real life. This will encourage you to look around and study from examples in everyday life.
