Comparing Six Sigma and Lean
Basically, Six Sigma and Lean systems have the same goals. They both seek to eliminate waste and create the most efficient system, but they take different approaches to how to achieve this goal. In the simplest terms, the main difference between Lean and Six Sigma is that they identify the root cause of waste differently. To summarize the key differences between Lean vs. Six Sigma, lean looks for ways to increase flow while Six Sigma focuses on achieving consistent results.
Lean himself, focusing on speed. It emphasizes reducing the amount of time between activities, events, and cycles. The shorter the cycle time, the more cycles you can complete in a certain amount of time. Lean also identifies areas where process waste and congestion can be eliminated. There are 8 types of waste that can be removed from business processes to reduce costs and time
Lean Six Sigma is a methodology that combines process speed with quality. To be a truly more efficient and effective organization in terms of operations and business processes, you need to have a Lean and Six Sigma methodology, having one without the other ending to produce a process of destruction.
The Six Sigma methodology is a quality tool that emphasizes the reduction of the number of errors in a process. It focuses on identifying variations in the type of data input, and view Root Cause Analysis to determine the source of the error. After all, what’s the point of finishing the process quickly if incorrect information is entered?
To ensure the success of the process and organization, a combination of lean and six sigma is required. Together lean and six sigma work through process mapping to model and automate the most efficient and quality workflows, enabling your company to maximize productivity while eliminating waste and reducing costs. Having a Lean Six Sigma approach to your business process is essential for any company to achieve operational excellence.
Ultimately, the problem may not be whether you should choose Lean vs. Six Sigma but how you can take the elements you like from each and apply them to solve problems in your own business.
