    Project managers very often describe their projects as simple or complex when discussing management issues. This indicates a practical acceptance that complexity makes a difference to the management of projects. The purpose of this paper is to propose a worker's skill-based metric for the complexity of a construction project activity using the concepts of functional decomposition and validate it. Based on a sample of 13 project activities from two construction projects, the empirical validation of the proposed metric using Spearman rank order coefficient exhibited a strong correlation between complexity of a project activity (CPA) and its completion time.
