Why do Six Sigma Professionals Need Minitab?

Quality management requires professionals to analyze statistical data to formulate meaningful solutions for problems. Minitab is a statistical software package that makes work easier and faster for quality management professionals.

Six Sigma professionals rely on the flexibility of Minitab to identify the problems in the business process and improve them accordingly. These professionals are highly trained and knowledgeable in identifying the defects in their organization’s business processes on their own. However, they need the help of statistical data analysis software like Minitab to interpret and evaluate large amounts of data.

Brief Introduction to Lean Six Sigma

Lean Six Sigma is a critical quality management methodology focusing on removing wasteful steps and reducing variation in business processes. It has been practiced in every industry since its introduction a few decades ago. Initially introduced in the manufacturing industries in the late ’80s, both Lean and Six Sigma quickly gained popularity due to their various benefits in quality development and improvement. Since then, every industry, from manufacturing to healthcare, packaging to supply chain, government services, and many more, has adopted Lean Six Sigma to improve the “quality” of its products and services.

Although, there is an ongoing debate about the validity of the Lean Six Sigma methodology shortly. There is enough evidence to support the fact that Lean Six Sigma is still relevant and trusted by many industry experts worldwide. This methodology is adaptable and flexible. The dynamics of the global economy can modify it. Six Sigma Professionals who are knowledgeable and trained in the Lean Six Sigma discipline are the change agents of their organizations. They can analyze the information needed to improve the business processes, evaluate the data inputs, and derive the desired results from them with the help of the DMAIC (define, measure, analyze, improve, control) phases of Lean Six Sigma.

Minitab is essentially used in the Measure and Analyze phases of DMAIC. It assists Six Sigma professionals in analyzing the trends in the market and predicting the outcomes of various processes. This statistical data analysis software allows organizations to improve their business processes and perform better than their competitors.

Thus, we can conclude that Minitab is a valuable tool for statistical data analysis that is necessary for Lean Six Sigma. Minitab has been used for statistical analysis purposes since the 1970s. It has found application in the various Six Sigma projects of organizations regardless of the type of industry. The software provides a quick and efficient way to compute the time-consuming data analysis required in numerous Six Sigma projects.

Here are some ways Six Sigma professionals use Minitab to improve the business processes of their organization:

  • Using Minitab, Six Sigma professionals can follow the DMAIC methodology of Lean Six Sigma, especially the Measure and Analyze phases.
  • Visualization of statistical data inputs is made more accessible through graphs, charts, and other tools.
  • Identify the problems or defects in the processes to help in Continuous improvement.
  • Predict the results of various improvement techniques and methods implemented in the business process.
  • Analyze the trends of past processes to reduce cost and time to complete the Six Sigma projects.
  • Manipulate data to suit the requirements of the organization and make changes wherever necessary

Minitab is an interactive tool that allows Lean Six Sigma practitioners to input statistical data and conduct analysis accurately. It provides tools like Histograms, Scatterplots, T-Tests, Control Charts, Boxplots, etc., to help professionals working in the quality development process of various organizations.  

Importance of Minitab for Six Sigma Professionals

Therefore, it is important for Six Sigma professionals to understand the functionality of the Minitab software package. Understanding the statistical data analysis tools required for quality improvement will make the job easier and faster. Six Sigma projects require optimum accuracy and computational speed to achieve organizational objectives. Minitab easily performs this function. Lean Six Sigma professionals understand the importance of Minitab in conducting data analysis and improving the organization’s overall productivity.

Like any other software, Minitab requires some basic understanding level to perform the functions. Training and certification in Minitab will help Six Sigma professionals master the tools provided in the software package. It will help them gain a comprehensive knowledge of statistical data analysis through Minitab and provide experience implementing these learnings in real-world situations.


Six Sigma professionals can use the reliable software solution provided by Minitab to improve their organization’s business processes and achieve their goals. Lean Six Sigma Green Belts and Black Belts usually use Minitab to manage and control the outcomes of the quality improvement processes. It is a powerful tool that helps build a continuous improvement culture in an organization and drives quality control. Six Sigma Lean Minitab is used by Green Belt Certified Professionals to analyze statistical data. These professionals may assist their organizations in minimizing flaws and creating efficient solutions to problems by utilizing Minitab.
