What is MiniTab, and how does it support transactional (service industry) Six Sigma?
“For more than 40 years, Minitab has been providing global solutions for quality improvement professionals.
The world of process improvement experts trusts Minitab for quality, analysis and results.”
View breif introductions:
Given the shortcomings of Excel, why would you use Excel over MiniTab?
“Because it is there.”
Why is MiniTab preferred to SPSS in the process improvement industry?
Minitab is a statistics package developed at the Pennsylvania State University, and the most commonly used
data manipulation and data cleaning package in the field, used most often in conjunction with the
implementation of six sigma, lean, CMMI and other data-driven process improvement methods.
Six Sigma Transactional Services (Service Industry) Components of the Training that Accompanies MiniTab/MiniTab supports:
Supports Lean through identifying, and cutting out unnecessary steps/data (cause of outliers)
Supports transactional Six Sigma by identifying and eliminating defects (process) and waste (paper etc.) to improve quality / efficiency
Why support from U of M, versus the stand-alone MiniTab (or pricier SPSS)?
Provided with the Lean Kata, Green and Black level online tools for the organization, with a focus on and real-time
support for concepts toward reducing costs, increasing quality, and accelerating process improvement.
Transactional Projects using MiniTab are supported by U of M resources for the employer.
Why is MiniTab use a best practice for Lean/Six Sigma service industry environments?
Quality control functionalities:
Large amounts of quick, statistical functionalities can be performed in Minitab, ranging from simple basic outlier identification, root cause identification, and statistics, to much more complicated multivariate analysis.
What makes Minitab stand out among many statistical softwares:
Its strength in quality contro tools, Minitab is equipped with almost all of the widely-used tools for process
control, including analyzing methods, graphics, designs of time-to-service/wait time experiments, etc.
Minitab is the leading software package used by quality improvement professionals in all kinds of industries around the world.
MiniTab clients include (manufacturing) GE, TOSHIBA, (service industries) Bank of America, SAMSUNG, etc.
