Due to the lack of efficiency analysis frameworks the benefits and costs of a lean production system remain vague in literature. This paper presents a framework to analyze the benefits and costs of the implementation of lean methods. A specific decomposition methodology is used which starts with a high-level performance indicator to break it down to operational indicators which individual lean methods can be assigned. The framework assists companies to track the contribution of individual lean methods to a key performance indicator.encost-benefitproduction systemlean620670working paper
