The purpose of this paper is to describe a leanness assessment methodology that takes into account the interaction between lean elements for computing the systemic leanness and for assisting continuous improvement of lean implementation.

Key elements determining the leanness level were identified by reviewing the relevant literature and were structured as a framework. Graph-theoretic approach (GTA) was used as the assessment methodology for its ability to evaluate the interaction between the elements in the developed framework.

Interactions between the lean elements were configured. Application of the proposed GTA for assessing systemic leanness was demonstrated. Scenario analysis was performed and a scale was developed to assist firms in comparing their systemic leanness index.
