PT. Insera Sena is a bicycles assembly company. The company produces its own brand bicycles as well as an original equipment manufacturer. One of the issues in the PT. Insera Sena is dead-stock. The dead stock arises due to huge variety of bicycles components, incompatible components, and other cases. In this reseach we proposed a solution to prevent the incompatibility components problem. We proposed compatibility maps. Those maps consist of grouping part tables. Moreover, using the compatibility maps, we proposed a software for simplifying choosing components in the bicyle design process. The compatibility maps have been evaluated by RND division and OEM division and they are relevant to the company needs.
