This paper focuses on the benefit of collaborative maintenance and current supported mobile technology. Mobile technologies and solutions are very popular in consumer applications and the exploitation of these technologies is expanding. In large-scale industries, maintenance of mobile solutions has not yet attracted much attention. One explanation is the lack of competence and knowledge for adopting mobile solutions successfully in professional use. Many companies have experienced problem in adopting the maintenance of mobile solutions due to inoperative telecommunication connections, lacking of suitable devices or insufficient implementation preparation. Another reason is that the benefits of mobile solutions have not been well-recognised, for example in maintenance domain. To the best of our knowledge, this research is of the first to investigate the roles of current mobile technologies in support of collaborative maintenance by eliciting an expert pane’s perspectives using a Delphi study. This paper seeks to present the benefits of collaborative maintenance, and the current roles of mobile technologies in supporting collaborative maintenance work in engineering assets organisations.
