The study aimed to conduct a cost-value analysis of the production process of a newly introduced batch of external doors in the context of value-added creation and to identify redundant processes that do not create puffy spa headband added value and for which appropriate corrective actions could contribute to their elimination.The result of applying improvement actions following the lean management concept was the optimization time nationalized analyzed by eliminating, among others, operations related to unnecessary transport and read more storage of products.In addition, the optimization production process impacted both shortening the process implementation time and reducing the costs of its implementation.Further activities will be related to the use of the presented methodology to analyze the processes implemented in the company in order to increase their efficiency.
