Assembly processes are characterized by frequent changes and a high density of information being displayed to workers. These challenges necessitate cognitive worker assistance solutions that are individually and situatively adaptable. Adaptation in digital assistance is primarily based on the type of human-technology interaction, which essentially can be deterministic, adaptive or adaptable. Hence, this paper presents a method for determining the type of adaptation appropriate for functionalities of cognitive worker assistance in series production. Adaptivity and adaptability function as design parameters concerning dialog initiatives in system interaction. While adaptivity is characterized by system-initiated changes, adaptability implies an interaction initiative of the assembly operator. Based on defined functionalities according to product- and process-specific framework conditions, scenario-based characteristics are identified and categorized. Beside different user perspectives, information technology efforts for implementing assistance systems are examined to evaluate the potential for enabling agile assembly systems.
