Worker assistance systems further optimize otherwise automated production systems by minimizing uncertainties of incorporated manual labor. This paper, subsequent to an elaborate use case and requirements analysis, develops a concept to advance these worker assistance systems from more or less isolated applications, that operate independently from other production and resource management platforms, towards an integrated solution using Industry 4.0-compliant Digital Twins of assistance jobs, products, workers and workstations, that document manually executed processes, their parameters, performances and configurations in an interoperable manner. Consequently, worker assistance systems will be established with little effort as a user- and processspecific enterprise resource planning frontend on the shop floorenIndustrial Worker Assistance systemEnterprise Resource PlanningIndustry 4.0 Integrationconference paper
