Several models to measure the degree of lean maturity populate academic literature. However, few make the proper connection between the application of lean tools and practices (T/P) and the fundamental objectives of lean manufacturing (LM). This is particularly true of the achievement of continuous flow and production lead time reduction. This article proposes, applies and evaluates a framework for measuring the degree of lean maturity in accordance with such premises.
Initially, LM specialists elected the most important lean T/P for the purpose of measuring the degree of maturity. The data were then processed using the Technique for Order Preference by Similarity to Ideal Solution technique. Based on these results, a framework was developed and applied to four manufacturing companies, from which degrees of maturity could be calculated and the applicability of the proposed framework evaluated.
Of the four companies studied, one presented a low degree of maturity, one an intermediate degree and the other two a high degree. These results proved sufficient to evaluate the effectiveness of the proposed framework.
The current level of maturity of the manufacturing companies chosen and their strengths and which areas need more attention could be identified from the application of the framework.
The framework contributes to the field of knowledge by providing a practical and easily applied way of measuring the degree of lean maturity in line with the fundamental objectives of LM.
