Lean Six Sigma represents the union of two robust methodologies that enhance products and processes while driving efficiency. This system combines Lean manufacturing, which is aimed at reducing waste and optimizing workflow, with Six Sigma, a data-driven method that strives to reduce variation in processes and enhance customer satisfaction. Together, Lean Six Sigma offers a comprehensive toolkit for businesses seeking to achieve operational excellence and continuously improve their performance.

What is Six Sigma?

Six Sigma is a methodology focused on improving business processes by minimizing variability and errors.

Six Sigma originated in the mid-1980s at Motorola, an American multinational telecommunications company. The methodology was developed as a response to the increasing demand for high-quality products and services. Bill Smith, a senior engineer and scientist at Motorola, is credited for devising the Six Sigma method. Since its inception, Six Sigma has been adopted by numerous organizations worldwide, underscoring its prominence and effectiveness in optimizing business processes and boosting efficiency.

This data-driven approach works by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. It uses statistical methods to quantify process performance, with the ultimate goal of achieving near-perfect results: a defect rate of 3.4 per million opportunities, to be precise. By striving towards this level of precision, businesses can enhance customer satisfaction, decrease operational costs, and increase their competitiveness in the market.

Data-driven Methods of Six Sigma

Mobile-Shop embraces the principles of Lean Six Sigma and the 5S System to deliver efficient, effective solutions to our customers.
Six Sigma implements a systematic, data-driven approach known as DMAIC—Define, Measure, Analyze, Improve, and Control. This methodology is designed to tackle inefficiencies and defects from the root cause. The Define phase is about identifying the problem, the Measure phase involves quantifying the problem, and the Analyze phase includes determining the cause of the problem. In the Improve phase, solutions are developed and implemented to eliminate the root cause, and finally, in the Control phase, continuous monitoring is performed to ensure the problem doesn’t recur. This structured approach allows organizations to use data and statistical analysis to drive process improvement and maintain efficiency.

What is the Lean Methodology?

The Lean methodology is a continuous improvement approach that focuses on eliminating waste and improving efficiency in all processes.

Also commonly known as Lean manufacturing, Lean methodology originates in the Japanese automobile industry, specifically within the Toyota Motor Corporation. Developed post World War II, the Toyota Production System (TPS), as it was initially known, was crafted to respond to the company’s specific manufacturing challenges. Eiji Toyoda and Taiichi Ohno spearheaded this efficient, waste-minimizing production approach. Lean methodology has since transcended the automotive industry, being adopted by various sectors worldwide for its ability to streamline processes and enhance efficiency.

At its core, Lean emphasizes creating more value for customers with fewer resources. It categorizes waste into seven types: overproduction, waiting, transport, extra processing, inventory, motion, and defects. By identifying and reducing these types of waste, businesses can streamline their operations, reduce costs, and improve overall productivity, thereby delivering greater value to their customers. This method engages all employees in the organization, fostering a culture of continuous improvement and efficiency.

Waste-Cutting Tools of Lean

Lean methodology also employs a variety of tools to help organizations reduce waste and improve efficiency.
The 5S System – sort, set in order, shine, standardize, and sustain – is a systematic method for workplace organization. This system minimizes waste by ensuring everything has a designated place, reducing the time and effort spent locating necessary items, and maintaining a clean, efficient work environment.

The Spaghetti Diagram is a visual tool used to track the flow of materials or people in a process. The model’s name comes from the tangled path, reminiscent of a plate of spaghetti, that often results when the actual flow is charted. This model helps organizations identify unnecessary movement and streamline workflows, significantly enhancing efficiency and reducing wastage. In collaboration with other Lean tools, these tools enable a holistic approach towards achieving Lean efficiency in various industries.

How to apply Lean and Six Sigma for performance improvement?

The primary objective of 5S is to enhance workplace organization, while Lean places its emphasis on reducing waste and creating value. On the other hand, Six Sigma primarily revolves around problem-solving driven by data and the reduction of variability.

Lean and Six Sigma can improve performance in the following industries.


  • In the healthcare industry, Lean Six Sigma and the 5S System can streamline patient care processes, reduce waste, and improve patient satisfaction. For instance, these methodologies can reduce patient wait times, streamline administrative processes, and decrease medical errors, all while maintaining high-quality patient care. 


  • In the retail industry, these techniques can be employed to enhance inventory management, improve customer service, and optimize store layout for better merchandise visibility and shopper experience. Retailers can achieve operational efficiency and higher customer satisfaction by reducing overstock, minimizing wait times at checkouts, and ensuring a clean, well-organized store environment.

Commercial and Multifamily Real Estate

  • Lean Six Sigma and the 5S System can significantly improve building maintenance and management processes for commercial and multifamily real estate. These methodologies can help manage inventory of maintenance supplies, streamline repair requests and processes, and enhance overall tenant satisfaction.


  • In the hospitality industry, these methodologies can be used to improve service delivery and guest experience. For instance, they can be applied in areas like food and beverage operations, housekeeping, and front desk operations, helping to reduce waste, minimize service delivery times, and enhance overall guest satisfaction.
