Project Information Overload & Role of PMIS in Managerial Decision-Making: A Study in Construction Companies of Oman

Most projects fail due to information overload. However, the project management information system (PMIS) and other technological support help the project managers (PM) make better decisions. This study looks at the issues of overloaded project information in Omani construction companies that the project managers must deal with. The study was based on quantitative data. The data is based on a survey through a structured questionnaire adopted from previous studies. The target population was the project managers (PMs) leading different construction companies in Oman, and about 296 PMs were approached. Two-stage sampling approach was adopted to collect the data and use SPSS software to analyse the data. The findings indicated that project managers can benefit from using a project management information system (PMIS), and project information overload had no adverse effects. The information system for project management favourably influences decisions. This research benefits project managers, especially those handling complex construction projects.   Multiple factors affect the decision-making process in construction companies; therefore, the research recommends exploring the contextual factors regarding the construction industry in Oman and assessing their impact on decision-making processes and project performance.
