In many developing countries, smart city initiatives are in their infancy. Like many other developing countries, smart projects in Morocco have been facing several challenges since their launch in 2016. The adoption of smart services requires the commitment and involvement of Moroccan citizens. This chapter focuses on a systematic literature review of the main studies dealing with factors that appear to improve end-user acceptance of services provided by Moroccan smart cities. A specific method known as PRISMA is being adopted to select and synthesize relevant studies in this field. The results obtained from the systematic review indicate that the unified theory of acceptance and use of technology (UTAUT) is the most utilized theory in the literature. Additionally, the examination of existing studies has revealed that successful implementation of smart projects requires decision-makers to consider the following factors: performance expectancy, ease of use, social influence, perceived cost, awareness, trust in technology, and trust in the government.
