Abstract: Evaluation of leanness level of an organisation becomes important as it identifies ill performing criteria and enables organisation to explore process from lean perspective and to focus more on weaker areas to improve operational performance. This work presents a study on leanness assessment of a manufacturing organisation using grey numbers approach. Assessment model comprises five enablers, 30 attributes and 90 criteria. Inputs are obtained from experts and are aggregated at three levels (enabler level, attribute level and criterion level). Overall grey performance index (OGPI) is computed as (2.192, 15.788), which indicates that the organisation is lean. Weaker areas are recognised based on grey performance importance index (GPII) and grey possibility degree (GPD) values. Results are validated using a decision support system. The practical implications are highlighted.
