Requirements for Modeling Frameworks in the Context of Assembly Work Instruction Development

This paper introduces requirements for a flexible modeling framework for creating digital work instructions (DWI) for industrial assembly processes. Designed to standardize DWI development, the framework organizes materials, tools, and hints into structured workflows, integrating diverse input data. Developed through a three-phase methodology data identification, framework creation, and validation its design is informed by a requirement analysis. A LEGO® use case demonstrates its application, highlighting its potential to improve efficiency, reduce errors, and support the integration of advanced technologies in manufacturing.
