Lean Six Sigma vs. Six Sigma: What’s the Difference?

Six Sigma is a big term amongst businesses. It’s known for being a huge resource for companies that handle complex projects. It’s a formula that’s so good some companies hire only Six Sigma black belts.

But what’s the difference between Lean Six Sigma vs Six Sigma? Which would be best for your business?

What you need is the in-depth review we just prepared for you, along with the tips you’ll find below. So go ahead and read on.

What Is Six Sigma?

Six Sigma is a data-driven methodology that aims to improve and maintain the quality of processes within an organization. It was originally developed by Motorola in the 1980s. It has since been adopted by various industries, such as:

  • manufacturing
  • healthcare
  • finance

The term “Six Sigma” refers to the goal of achieving a level of performance where only 3.4 defects occur per million opportunities.

What sets Six Sigma apart from other quality improvement approaches? It emphasizes rigorous statistical analysis and the use of specific tools, such as DMAIC (Define, Measure, Analyze, Improve, Control). These are used to identify and eliminate sources of variation that lead to defects.

By implementing Six Sigma, organizations can reduce costs and improve efficiency. Ultimately, they can deliver better products and services to their customers.

What Is Lean?

Lean refers to a business methodology that focuses on increasing efficiency and eliminating waste in the production process. This approach was originally developed by the Toyota Motor Company. It has since been adopted by countless other organizations across various industries.

At its core, lean is about continuously identifying and eliminating non-value-adding activities. This results in a streamlined and more productive workflow.

This not only leads to financial savings. It also improves lead times, quality, and customer satisfaction. To successfully implement lean, commitment from all levels of the organization is necessary.

What Is Lean Six Sigma?

Lean Six Sigma is a powerful methodology that combines the principles of lean manufacturing and Six Sigma. The goal is to improve business processes, reduce waste, and increase efficiency.

It focuses on identifying and removing any waste or defects in a process. This is while also striving for continuous improvement. To achieve these goals, Lean Six Sigma follows a structured approach. It utilizes various tools and techniques, such as:

  • value stream mapping
  • root cause analysis
  • statistical analysis

This methodology has been successfully implemented in various industries. It results in significant cost savings and improved customer satisfaction.

What Are Considered Waste?

In Lean Six Sigma, there are eight types of waste that are considered to be common across all industries:

  1. defects
  2. overproduction
  3. waiting
  4. on-utilized talent
  5. transportation
  6. inventory
  7. motion
  8. extra processing

Defects refer to any errors or mistakes in the process that result in rework or scrap. Overproduction is producing more than what is needed, leading to excess inventory and storage costs.

Waiting is the idle time between steps in the process. Non-utilized talent refers to not utilizing the full potential of employees. Transportation involves unnecessary movement or transfer of items.

Inventory is raw materials or finished goods that are not actively used. Motion is any unnecessary movement of people or equipment. And finally, extra processing is any unnecessary steps or activities in the process that do not add value.

In Lean Six Sigma, these wastes are considered to be the root cause of inefficiencies and are systematically eliminated to improve overall performance and customer satisfaction.

Exploring the Main Differences

While they have similar goals, there are core differences between the two. Here are some of them.

Focus and Objectives

There are some key differences between the two in terms of focus and objectives. Six Sigma focuses on identifying and eliminating defects in a process. On the other hand, Lean Six Sigma adds the element of reducing waste and increasing value for the customer.

The objective of Six Sigma is to achieve near-perfect quality. Meanwhile, Lean Six Sigma aims to achieve both quality and speed.

Overall, Lean Six Sigma puts a greater emphasis on customer satisfaction and overall value creation. It is a more holistic approach to process improvement. If you’re looking for Lean Six Sigma Training courses for your professional development, check out https://www.theleansixsigmacompany.co.uk/.

Methodologies and Tools

Six Sigma uses statistical tools to analyze data and identify the root cause of a problem. On the other hand, Lean Six Sigma uses a broader range of tools. This includes Value Stream Mapping and Kaizen events. The goal is to streamline processes and improve overall efficiency.

Both methodologies have proven to be effective in achieving process improvement. The choice between the two ultimately depends on the specific needs and goals of the organization.

Application Areas

Six Sigma is primarily used in manufacturing and production industries. It focuses on reducing variation and improving product quality. On the other hand, Lean Six Sigma is applied in a wider range of industries, including:

  • healthcare
  • service
  • financial sectors

The difference in application areas makes Lean Six Sigma a more versatile and adaptable approach compared to Six Sigma.

When to Use Six Sigma

Six Sigma can be applied to any industry and organizations of any size, from small businesses to large corporations. It is most commonly used when a company wants to:

  • reduce costs
  • improve quality
  • increase customer satisfaction
  • drive overall business growth

Six Sigma is especially useful when dealing with complex processes that involve a large number of variables and when there is a need for data-driven decision-making.

When to Use Lean Six Sigma

Lean Six Sigma is most effective when used to address complex problems and optimize processes that require a high level of precision and consistency. Additionally, Lean Six Sigma is ideal for situations where there is a need for continuous improvement and a data-driven approach.
