What is Lean Six Sigma?
Six Sigma is a methodology that gives businesses the resources they need to develop their business process. This change in efficiency and reduction in process variance helps to reduce defects. Besides, it boosts earning, employee productivity, and product or service quality.
Lean Six Sigma is a tool for reducing waste and increasing consumer satisfaction. For efficient problem-solving, this managerial concept employs the Lean and Six Sigma approach. When a team uses this method, they can avoid problems with a service or product. Besides, lean six sigma principles remove potential financial waste.
Difference between Lean, Six Sigma & Lean Six Sigma
Now that we know what lean six sigma is, let’s discuss the differences between Lean & Six Sigma.
Six Sigma is concerned with reducing process variation and improving process control. In contrast, lean is concerned with eliminating waste (non-value-added processes and procedures). Furthermore, lean promotes work standardization and flow.
Since process improvement involves elements of both methods to achieve meaningful results, the distinction between Six Sigma and lean have blurred. Hence, many organisations are using the word “lean Six Sigma” more frequently. When it comes to identifying problems, Lean focuses on waste (Muda, mura, muri). In contrast, Six Sigma focuses on variation or any deviation from the target results.
Lean Six Sigma is a data-driven, fact-based improvement theory. It:
- Prioritizes defect prevention over defect detection.
- Improves customer loyalty and bottom-line performance.
- Lowers variance, waste, and cycle time.
The process encourages job standardization and flows, resulting in a competitive advantage. Therefore, it applies everywhere there is waste, and every employee should be a part of it.
Lean Six Sigma is a collaborative management approach. It solves problems using a collective lean toolkit. The company goes through five principles of Lean Sigma to reduce waste and fix issues. Following the principles of lean six Sigma is a must for maximum efficiency.
What are the Lean Principles?
Lean manufacturing has long been thought to be a way to increase manufacturing productivity. But it can be extended to any sector or production process in any industry. Lean, for example, industries such as manufacturing, finance, healthcare, IT, and the military are using lean principles.
On a smaller scale, the concepts can even be used to organise your laboratory or workspace.
Toyota first developed lean as part of the Toyota production system. It was built around the work of Shewhart & Deming. Toyota was a client of Deming’s. Since then, the company based its operational management activities on his teachings. The removal of waste is the central tenet of Lean.
In reality, “a collection of tools that assist in the detection and continuous removal of waste” is a reasonable definition of the Lean approach. If a company, such as Toyota, engages in large-scale, high quantity manufacturing, a waste-involved method indicates that the company generates large-scale, high-quantity waste. This is something that no organization wants to do. Also, the Lean methodology analyses the company process with software.
In manufacturing, there are five fundamental lean principles.
The needs of the customer often determine the value of a commodity. What is, for example, the production and distribution schedule? What is the starting point for the price? Furthermore, what are the other critical conditions or demands that must be fulfilled? This data is critical for determining meaning.
Map the Value Stream
After determining the value (end goal), the next step is to chart the “value stream”. It involves all the steps and processes involved in bringing a given product from raw materials to delivery to the consumer. Thus, value-stream mapping is a straightforward exercise. It describes all the activities that move a product or service through a process.
Design, administration, manufacturing, procurement, HR, distribution, and customer support are all examples of processes. The aim is to create a “map” of the material/product flow through the process on one page. Furthermore, to recognize any move that does not add value, make plans to get rid of them. Process re-engineering is another term for value stream mapping. You will have a greater understanding of the entire company process with this.
After removing waste, the whole department must become cross-functional. It makes sure the remaining steps in the manufacturing process remain free of delays. Altogether, this will lead to huge gains in creativity and efficiency.
With improved flow, the time for marketing a product and delivering it to the customer is shortened down. Your customer can buy a product from you and get it delivered instantaneously in weeks. They don’t have to wait for months. Meanwhile, your company gets to cut back on the huge expenses of inventory. Because there is no need to stockpile resources or build the product in advance.
Thus, this step lets you cut back on production cost, making the price of the goods cheaper. In addition, this phase makes your customer more satisfied.
Getting through Steps 1-4 is a good start. However, the fifth stage is probably the most crucial. It helps incorporate lean thinking and process management into the company’s culture. As the gains continue to mount, keep in mind that lean is a dynamic framework. Hence, it needs relentless effort and diligence to perfect.
Every employee should be a part of the lean implementation process. Experts say a method needs to pass through value stream mapping multiples times. Then it will be considered an authentic lean process.
Six Sigma Principles
Motorola was the first to produce Six Sigma in the late 1980s. Bill Smith, a quality engineer, developed the technique. He wanted to cut out mistakes. His intention was to improve the operation process of quality and measurement. The Motorola systems were tolerant of error rates. And it resulted in excessive scrap, rework and redundant testing. Besides, it caused huge customer frustration.
The Six Sigma methodology aimed to recognize and eliminate any source of variation in the process. Because the lack of variation will give a predictable result. However, this result can be accepted only if it is error-free and meets customer satisfaction.
The four stages of Six Sigma are:
This phase sets the boundary for the process under investigation. The probable outcome is set according to customer expectation or feedback. In short, this phase primarily focuses on enhancing customer experience.
The current output of the process, product, or service is evaluated in this step. It determines what is actually happening, particularly from the perspective of the customer. This phase ensures that the study and solution are based on real-world performance. In essence, it doesn’t rely on hypothetical or anecdotal data.
This step evaluates potential improvements to the method, product, or service. The team then moves on to design and test a collection of changes and solutions. In addition, it ensures that the solution has the desired effect. The variance is minimized or removed in this phase.
This phase introduces the modifications and changes the supporting systems. Furthermore, the project team places the process, product, or service under review. The team uses statistical process control. This phase also ensures the complete execution of the solution. The control measures detect if output begins to deteriorate.
Different Six Sigma Qualifications
SIX SIGMA offers a variety of certifications, also known as “belts.” Yellow, Green, Black, and Master Black are the most widely used and recognized Six Sigma Belts. Certain organizations often assign white Belts. Six Sigma has no uniform certification body. The Belts do not build on each other or serve as prerequisites.
The following is a brief rundown of the various Six Sigma Belts:
Six Sigma White Belt
It is the entry-level qualification that covers the fundamentals of Six Sigma. White belts aid programs by assisting in change management in the company. Also, they work with local problem-solving teams.

Individuals who achieve the rank of Master Black Belt in Six Sigma are able to teach others the concepts of Six Sigma. You’ll learn how to create key metrics and a strategic direction, which will eventually inform all of a company’s Six Sigma decisions.
Lean Six Sigma Principles
Both Lean & Six Sigma define value based upon the customer’s experience. Lean & Six Sigma principles are most compatible when implemented together. Data collection in Lean Six Sigma Project can support both lean analysis & six sigma analysis. In short, improvements using either approach will reduce waste and variation.
Lean Six Sigma is not only used in manufacturing operations. The principles are integrated and used in all industries. For instance, government, consumer, education and non-profit organizations.
Successful programs throughout industries adopt the following lean six sigma principles:
Addressing a Real-World Problem
Lean Six Sigma is a bottom-up and top-down approach. Problem selection is linked to the top-down aspect. The Lean Six Sigma project teams are concentrating on real-world issues that are currently affecting consumers and processes.
When it comes to rework and repair activities, as well as dealing with customer concerns, team members are often affected by the issue. This gives the project a sense of urgency and relevance. It isn’t just “busy work,” but genuine work.
A cross-functional team usually handles the Lean Six Sigma projects in a company. A cross-functional analysis is needed to prevent the sub-optimization of the process. Consequently, the viewpoints of the organizations involved and affected by the project are included in the problem analysis by including a cross-functional team.
A cross-functional team plays a key role in the implementation of the solution. The different team members’ in-depth experience is beneficial in understanding the issue and the consequences of the data. These diverse viewpoints are critical in assisting the team in developing a solution. Overall, team analysis solves the immediate issue while also reducing waste and variation in other areas of the process.
Solution Addresses Problem’s Root/Cause
The methods used in Lean Six Sigma are used to determine if the problem is caused by a particular cause or a general cause. Your project team will be able to find the real root cause or causes after making this distinction. In addition, the team should devise a problem-solving approach that is suitable for the situation. If the trigger is unique, you may devise a unique solution. The team should redesign the mechanism if it is a common cause.
The final step of lean six Sigma is the control phase. In the control phase, the organization updates the corresponding system and implements the solution. In addition, the project team coaches process operators and managers on the use of the solution.
