The term "user adoption" in software deployment refers to the process by which users begin to utilize a new software application or system. Successful user adoption involves several stages, including awareness, training, and ongoing support. Understanding user needs and providing comprehensive onboarding can significantly enhance adoption rates. Factors influencing adoption include user experience, the software's perceived value, and the organization's culture. Increased user adoption leads to improved productivity and maximized return on investment for the software in question.
