Meta-analysis of Lean case studies for the business process improvement

Each company defines its goals to achieve an improvement approach for its business processes. However, identifying potentially achievable goals before the implementation of an improvement plan could prevent the company from wasting considerable time and budget on unreasonable goals that do not meet their expectations. Our meta-analysis provides, in this sense, a preliminary study of expected objectives through the implementation of the Lean approach in different fields and by an analysis of several cases published in the literature.
