The causal relationship among factors of lean tool implementation with a DEMATEL method in Indonesian Aerospace

The purpose of this study is to examine the causal relationship among factors that impact the utilisation of safety, quality, cost, delivery, and people (SQCDP) as a component of lean manufacturing implementation to optimise the implementation in the directorate production of Indonesian aerospace. The study employs the decision-making trial evaluation laboratory (DEMATEL) method and leverages the expertise of specialised individuals within the directorate production, such as division managers and lean agents. Furthermore, a method of surveying was implemented to retrieve data from purposeful sampling. A cause-and-effect diagram was developed and provided importance degrees for all factors. The main findings of this study are the visualisation of the causal relationship among factors of SQCDP implementation through digraphs. This study helps the organisation to provide a clear understanding of the fundamental factors that should be given priority and recommended for further action to achieve long-term progress of lean implementation.
