Abstract

Project sponsors have sought to develop the necessary competence to address various challenges they face during project development, implementation, and exploitation by employing different initiatives including the engagement and use of external consultants. However, doing so is associated with a number of consequences, including a significant risk of exacerbating project complexities. With this in mind, we set out in this article to examine the salient differences in the key project complexities between projects engaging consultants and those not engaging consultants. Data are obtained from 146 project management practitioners engaged in projects in Canada and the USA. Data analysis is undertaken using three-way multidimensional scaling. Findings as relates to the key complexities associated with information systems projects, points to the manifestation of six broad dimensions of complexity namely 1) “Variety,” 2) “Control,” 3) “Criticality,” 4) “Scope and repetition,” 5) “Information,” and 6) “Dependence.” As relates to how consultant engagement changes the salience of these key project complexities, we find that consultant engagement leads to more varied and stronger structural complexity and higher salience of interpersonal and organizational complexity.
