This paper describes approach to evaluate and compare efficiency of lean management projects, using a set of techniques known as Data Envelopment Analysis. DEA is a non-parametric linear programming method used to the efficiency evaluation of decision making units. Lean methods have been widely used as a tool for improving operational performance and also have been successfully implemented in many manufacturing and non-manufacturing organizations. This paper aims to develop a mathematical model to evaluate the efficiency of lean management projects. Paper provides the identi?cation of important inputs and outputs for projects that are then analysed using DEA. Working with planned indicators values, this model helps to identify one or more projects that result in the maximum bene?t to the organization. Using the real indicators values after implementation of a project, it can help to determine how the project was successful as compared with similar implemented projects.
