The concept of the technology adoption lifecycle is essential for understanding user behavior as it outlines how new technologies are adopted by different groups over time. This model categorizes users into segments such as innovators, early adopters, early majority, late majority, and laggards. Each group exhibits unique characteristics regarding their willingness to embrace new technologies. Understanding this lifecycle helps organizations tailor their marketing strategies, support structures, and product development to cater to the varying needs and behaviors of their target audience.
