The Industry 4.0 era is challenging manufacturing industries to improve their flexibility and responsiveness to change various needs by upgrading their operations strategies, methods, and technologies. Software product line engineering (SPLE) is a promising software development paradigm that satisfies those needs. Several industries that have adopted this concept have had promising results. However, different industries, especially small and medium enterprise (SME) manufacturing, have applied different approaches because there is no standardized flow applicable for different types of settings. This study arranges procedures for implementing SPLE in certain domains with an extractive approach. Requirements engineering is carried out at each SME manufacturer referring to their respective supply chains. Each identified application feature is mapped to build a feature model. The extended unified modeling language for delta oriented programming profile is used to represent the results of requirement gathering for a more abstract architectural design. The result of this research is an approach to performing domain engineering of SPLE for SME manufacturing. ICIC International ©2024 ISSN 1881-803X.
