In the light of the proceeding demographic change in Europe, companies have to face the challenge to cope with the changes of the working environment with a continuously aging workforce. Hence, the design of age-based work systems and processes becomes an important factor of German companies. Having this in mind, a task analysis and screening procedure (ATS) was developed to consider age-related changes directly by planning and to avoid an overstraining in older people. With the conception and evaluation of ATS, a first basic approach could be generated to identify age-critical fields of activity in the product development and production process. Due to the comparison of work requirements and age-related abilities, it is possible to illustrate age-related spheres of activity and to infer design recommendations in order to design work systems in a corrective and conceptive way.
