User inertia is a real innovation adoption problem that cannot be seen or grasped. How to overcome user inertia while introducing innovation has become a key factor in today's society. Based on the background of requirements engineering, the goal of this thesis is to study and understand the relationship between user inertia and innovation adoption, including whether the type of innovation has an impact on user adoption and how to use strategies to reduce this impact. Through an online survey of 60 users and a systematic literature review of a series of articles, we have concluded the following points: RI has a greater impact on user inertia, while II has almost no impact; neither RI nor II has a significant impact on user satisfaction. Not only that, but through literature review, we have also concluded a comprehensive strategy to deal with the adoption problem caused by user inertia.
