Lean Six Sigma and its Importance

What really is Lean Six Sigma?

Lean Six Sigma is a combination of two popular process improvement methods, Lean and Six Sigma that paves operational excellence to describe it in simple words. These proven approaches provide organizations with a clear path to accomplish their missions as quickly and efficiently as possible.

Before going into the major details, it is important to clarify the concept of process improvement. Since Lean Six Sigma is a process analysis and improvement system, we will first discuss these terms.

What is the process?

It is a series of steps involved in creating a product or providing a service. Almost everything we do is a process: tie our shoes, bake a cake, treat a cancer patient, or make a cell phone.

What is process improvement?

Process improvement requires employees better to understand the current state of operation of a process to remove barriers to serving customers. Since every product or service is the result of a process, acquiring the skills necessary to eliminate waste, rework, or inefficiency is essential to an organization’s growth.

Work in a process or process

Employees are hired based on their experience in a certain field. Everyone is good at their profession like bakers are good at baking, and surgeons are good at surgery. Professionals are experts at working on a process, but they are not necessarily experts at working on a process. Learning to work and improve processes requires experience and training in continuous improvement. This is where Lean Six Sigma comes in.

The origins of Lean Six Sigma

Lean was born at Toyota in the 1940s and Six Sigma at Motorola in the 1980s. Although they were taught as separate methods for many years, the line has faded, and the teachings are now commonplace. Lean and Six Sigma combined to reap the best of both worlds.

Understanding both approaches and the toolkits that accompany them is extremely valuable in troubleshooting. It doesn’t matter where a tool comes from, Lean or Six Sigma, as long as it gets the job done. With both of these methods, you have the best chance of applying the right mindset, the right tactics, and the right tools to solve the problem.

Who benefits?

The company and its clients

Lean Six Sigma works for organizations of any size. All of the small and medium-sized companies can achieve the same success as large companies. Small organizations can be more agile, with fewer staff and less bureaucracy to navigate.

This method and Its application help increase revenue and reduce costs while freeing up resources to add value where the organization needs it most. The final winners are the company’s customers who receive consistent and reliable products and services.


Lean Six Sigma doesn’t just improve profit margins; It positively affects employees by involving them in the work of improving their processes. Since employees are closer to an organization’s real work, the delivery of products and services, their intimate knowledge ultimately makes them the best resources to analyze and improve these processes’ efficiency and effectiveness.
