In Germany, the demographic aged 60 and above constitutes over a quarter of the total population, a proportion projected to surpass a third by 2050. Notably, this demographic possesses substantial purchasing power, as evidenced by higher income levels among German seniors, thus underscoring the significance of addressing their needs.

Despite the presence of innovative behavior across all age groups, research suggests that the transition from ideas to prototypes diminishes with age (Wellner & Herstatt, 2014). Consequently, understanding the developmental challenges and various influencing factors that impede the progression to the development phase for older individuals remains an area requiring further exploration.
