Scholarcy highlights

  • Over the last three decades, there has been a growing focus in both manufacturing and service organizations on implementation and development of improvement techniques to reduce costs and increase benefits
  • Maturity models identified in the literature do not provide a practical measurement system for assessment of lean implementation in order to meet the explicit objectives at the shop-floor level
  • The conceptual definitions of maturity phases are analyzed from different perspectives during the development of lean maturity model in order to design an appropriate model of leanness for production cells in this study
  • The main purpose of this study is to develop a lean maturity model adapted to the specifications of the production cells in order to assess the leanness and performance of operational level lean initiatives from different perspectives
  • The proposed LMM for the functional level is designed based on the reviewing the lean concept from different perspectives and reviewing the best practices of lean and operational excellence models
  • As a generally accepted rule, when the average result of all indicators in a level was equal or less than 70%, the evaluation of production cells stopped in that axis-level
  • The LMM presented in this study focuses on the necessary activities needed in the level of operations as a most important part of a value stream
  • The model can be practiced by lean practitioners and can be improved in details based on the created knowledge
