Complexity and Project Management: A General Overview

Table 1

Main factors affecting project complexity.

Factor

SizeTo consider it an indication of complexity, the organizational structure of the project should be over a minimum critical size and their elements need to be interrelated.
Interdependence and interrelationsAn event in an interconnected structure can cause totally unknown effects on another entity inside the structure.
Goals and objectivesThey must be adequately and properly defined both at a strategic and at an operational level.
StakeholdersThe number of project participants and how the information flows between them are a key factor affecting project complexity.
Management practicesRelationships between project participants, suppliers, overlapping of activities, methods, and techniques are factors that affect project complexity.
Division of laborAdding project organizational structure by dividing labor, the way for personnel selection, and the level of pressure on this personnel to achieve project objectives are factors that increase project complexity.
TechnologyTask scope or the variety of tasks that need to be accomplished is the most critical dimension of technology. It explains why there is a need for a variety of technologies and a given level specialization in each of them.
Concurrent engineeringIt breaks down functional and departmental barriers by integrating team members with different discipline backgrounds often known as cross-functional teams.
Globalization and context dependenceGlobalization boots complexity by the erosion of boundaries, higher mobility, heterarchy, and higher dynamics. It can be an essential feature of complexity.
DiversityA higher number of elements and a higher variety across elements increase complexity.
AmbiguityIt expresses uncertainty of meaning in which multiple interpretations are plausible.
FluxFlux is affected by external and internal influences. It also implies constant change and adaptation to changing conditions.
