Lean Six-Sigma

Lean Six SigmaProgram Objectives

The importance of Lean and Six Sigma to organizational improvement are based upon a demonstrated record of success over the last 30 years. Six Sigma and Lean have become required knowledge for professionals involved in continuous improvement and provides an accelerated path to leadership. This concentrated area of learning and research focuses on the Lean Six Sigma at the project and strategic levels.  Students learn how to utilize DMAIC, a focused and measurable project management methodology structured for organizational learning. Strategic understanding focuses on how Six Sigma and Lean strategies fit for a larger enterprise continuous improvement system and how to apply these techniques to solve and prevent critical organizational issues. Students striving to be leaders in industry and academia, or consulting, with an emphasis in developing research related to this field, would strongly benefit. 

Six Sigma has changed over time from a pure quality function to an overall improvement methodology. All organizational functions may be included in a Six Sigma strategy and encompass the entire values supply chain, defined by the organizations core and enabling processes to deliver the institution’s mission.

Apart from the research aspects of the program, students will have the opportunity to complete a real-world business project that implements the key concepts of Six Sigma. Completing such a project is a requirement for certification. Preparing you to become certified is an option student may choose to pursue after being admitted the program.

  • Big Data and Six Sigma
  • New Six Sigma applications in industry and service
  • Six Sigma implementation and country culture
