A roadmap for a leanness company to emerge as a true lean organization

The problem this work aims to solve is the improvement of the leanness level of a company jeopardized by the lack of lean engagement. The objectives of the research are to present a method based on a lean self-assessment approach, consisted of a qualitative self-assessment method based on lean elements that drives an index definition associated with a roadmap. The method consists in providing a roadmap for the assessed enterprise composed by the company’s lean index, recommendations and countermeasures deriving from Delphi and Kendall Coefficient of Concordance (W) application among lean experts, leading the assessed enterprise to achieve results in terms of lean engagement, autonomy, and decision support criteria for future resource allocation. The results demonstrated that method can highlight gaps where additional improvements and investments would be necessary in the assessed enterprise. Finally, the study concludes that the lean performance identification associated to a lean roadmap in a company can be a highly effective tool to improve lean adoption in a leanness organization.
