Facility or facilities management (FM) helps ensure that the built environment is efficient, safe, comfortable, and sustainable. The goal of FM is to raise productivity and improve people's quality of life. FM involves working with a variety of service providers to ensure that buildings and associated facilities are well maintained. The role of the facility manager is becoming more prominent in a digitally enabled world. The recent pandemic has boosted the rate at which innovation is being embraced in most organisations. This research will look at the current trends in FM that are emerging as a result of digitalisation. The main objective of this research is to propose the FM digitalisation model, which might influence future FM practices. This systematic literature review is based on a search of articles across Scopus and Google Scholar using keywords such as "facilities management" and "digitisation". On July 6th, 2022, the searches yielded 614 articles, including 64 articles in Scopus, 113 articles in WoS, and 437 articles in Google Scholar. After screening, 29 Scopus articles, 93 WoS articles, and 398 Google Scholar articles were excluded. According to this study, the field of FM digitalisation is still in its early stages of development. The study also identifies FM digitalisation trends over the previous twelve years, establishing contextual knowledge. As a result, a conceptual model that focuses on sustainable FM digitalisation is proposed.
