Who we are – The Lean Enterprise Institute (LEI) and Lean Global Network (LGN)

The Lean Enterprise Institute is a learning and sharing, mission driven non-profit organization with the goal of spreading lean thinking and practice throughout the World. LEI was founded by James P. Womack in 1997 (co-author of worldwide known lean books Lean Thinking and The Machine That Changed the World).

The local institutes are affiliates of the Lean Global Network with Headquarters in Boston, USA. The 18 Lean Global Network Affiliates support lean transformation around the World by developing lean practitioners and leaders through education, coaching, action research, events and learning materials. Lean Enterprise Institute Hungary – the 18th Affiliate of LGN – was founded in 2011.

Our definition of Lean Thinking &Practice: 
Systematically develop people and continuously improve processes to provide value and prosperity while consuming the fewest possible resources.
The Lean Practitioner Program (LPP)

The 8 days Lean Practitioner Program was developed by the LGN Affiliates as a certification program1 to combine the knowledge and skill development2 and to respond to the companies’ challenges on their lean journey. Providing this course we also generate new lean knowledge and share with other lean practitioners in the spirit of continuous improvement and PDCA and to further develop the LGN Lean Practitioner Program.

The Lean Practitioner Program provides a framework to learn the fundamentals of lean thinking, apply it in practice and reflect on the development of the participants and the organization as well.

This curriculum is also part of the University of Barcelona postgraduate MSc program (Organization and Engineering of Industrial Plant Production and Management (ENGIPLANT)).

Process of the Program
