Hey everyone, welcome to this lecture comparison of lean with other process improvement methodologies. In this lecture, you will briefly understand the difference between Lean Six Sigma and Theory of Constraints. You will learn this comparison under four distinct categories. The goal of each methodology, its approach, its focus, and its results. Let's begin goal. The goal of any lean project is elimination of waste from the system.

Six Sigma is focused on variation reduction and Theory of Constraints is focused on managing constraints. Now, let's talk about approach. He approach of lean methodology is that it begins with it Define value, then it identifies the value stream. Then the flow strives to implement a pole system and finally focuses on perfection. The approach of Six Sigma is defined in five steps, generally acronym as B Mac, D Mac stands for define, measure, analyze, improve and control. Unlike the other two, the Theory of Constraints has a different approach.

It identifies constraints, exploits it subordinate processes, elevates constraints and repeats cycle. Let us now talk about the focus of each methodology. Lean is flow focused. Six Sigma is problem focused and Theory of Constraints is focused on system constraints. Finally, let's talk about the results. Lean strives for reduced flow or cycle time.

Six Sigma focuses on uniform flow output with little or no variation. variation is an enemy to six sigma, while Theory of Constraints results in fast throughput. This summarizes a brief comparison of lean versus other process improvement methodologies. It is now time to go through a success story. It is titled lean training leads to $1.2 million in impact. Thank you for attending.

See you in the next lecture.
