Deviation from a state of perfect uniformity: An indicator of structural complexity in projects

The complexity of projects arising from interconnectedness between activities is believed to be one of the most significant challenges for managing projects. Although the literature has long appreciated the significance of measuring complexity, research on this topic is weakened by the lack of a method that accounts for a diverse set of structural characteristics of project networks. To evade this pitfall, this paper introduces the concept of perfect uniformity and develops a comprehensive measure of structural complexity in projects. The proposed method is validated by applying it in two real‐life projects. The validation results confirm that project complexity is positively associated with a higher level of deviation from a state of perfect uniformity. This research is among few studies that draw on the concept of emergence and point out the importance of a system‐level approach in project management to analyse the interdependency between multiple interconnected activities.
