Why do Six Sigma Professionals Need Minitab?

Quality management requires professionals to analyze statistical data to formulate meaningful solutions for the problems at hand. Minitab is a statistical software package that makes the 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 the business processes of their organization on their own. However, they do 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 an important quality management methodology that focuses on the removal of wasteful steps and the reduction of variation in the business processes. It has been in practice in every industry since its first introduction, a few decades ago. Initially introduced in the manufacturing industries in the late ‘80s, both Lean and Six Sigma quickly gained in popularity due to their various benefits in quality development and improvement. Since then, every industry from manufacturing to healthcare, packaging to supply chain, services to government, and many more have adopted Lean Six Sigma to improve the “quality” of their products and services.

Although, there is an ongoing debate about the validity of the Lean Six Sigma methodology in the near future. There is enough evidence to support the fact that Lean Six Sigma is still relevant and is trusted by many industry experts around the world. This methodology is adaptable and flexible. It can be modified in accordance with the dynamics of the global economy. 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. Through this statistical data analysis software, organizations can improve their business processes and perform better than their competitors.

Thus, we can conclude that Minitab is a useful tool for statistical data analysis that is a necessary part of 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 of computing 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 easier through graphs, charts, and other tools.
  • Identifying the problems or defects in the processes to help in Continuous improvement.
  • Predicting the results of various improvement techniques and methods implemented in the business process.
  • Analyzing the trends of past processes to reduce cost and time to complete the Six Sigma projects.
  • Manipulating data to suit the requirements of the organization and making 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 as well as faster. Six Sigma projects require an optimum level of accuracy and computational speed to achieve organizational objectives. This function is easily performed by Minitab. Lean Six Sigma professionals understand the importance of Minitab in conducting data analysis and improving the overall productivity of the organization.

Like any other software, Minitab too 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 get a comprehensive knowledge of statistical data analysis through Minitab and provide experience in implementing these learnings in real-world situations.


Six Sigma professionals can use the reliable software solution provided by Minitab in improving the business processes of their organization and achieve the 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.
