Project complexity is the property of a project which makes it difficult to understand, foresee, and keep under control its overall behavior, even when given reasonably complete information about the project system.[1]
With a lens of systems thinking, project complexity can be defined as an intricate arrangement of the varied interrelated parts in which the elements can change and evolve constantly with an effect on the project objectives.[2] The identification of complex projects is specifically important to multi-project engineering environments.[3]
The domain was introduced by D. Baccarini in 1996.[4]
