The chief aim of this research paper is to investigate the factors impacted the PM software casual end-user perspective in private HE in Egypt; these factors include tool selection, adoption intention, and user acceptance of computer technology. The study focuses on infrequent end-users (students and staff members). The selection of the HE sector in Egypt is the large number of the end-users. This group of end-users represents casual or infrequent user of PM software who are the potential usual end-users. The previous studies investigate project issues i.e. Critical Success Factors (CSFs), PM tools, techniques, usage extent, and importance across sectors and countries with narrow focused statistics on end-users" tools, methods, and techniques" preferences, the most frequently used software (s), reasons of software selection, and learning and adoption motives.Differentiating the influences based on individuals categories provides managers and supervisors with a clear road map for promoting learning and adoption processes. Investigating such influences results in maximizing the gained PM benefits, provides a better understanding of individuals retentions, PM importance and value, learning and adoption reasons, and grants PM software developers the required information and statistics about end-user needs and preferences in relation to tools, methods, and used techniques. This is an essential step in the activity of identifying the requirements of software development process.The study targeted participants were Business Administration-BA students and staff members in the private HE in Egypt. The survey questions were classified according to the participant's category (student or staff member). These participants were selected on the basis of the nature of their study which is unique in terms of its causal usage pattern of PM software. Both students and staff members were randomly investigated. They belonged to different departments, thus the collected data required independent analysis.
