Construction projects are characterized by complexity and high levels of variability, which often lead to reduced performance, cost overruns, and inefficiencies in planning. Recognizing workflow variability as a critical challenge in the construction industry, this study aims to systematically identify and categorize its key causes. A quantitative approach was employed, utilizing a structured questionnaire informed by an extensive literature review, which identified 38 potential causes. The data were analyzed using exploratory factor analysis (EFA), resulting in the retention of 21 causes, grouped into four principal factors: resources, management and planning, material, and prerequisite. The study provides empirical insights into the primary sources of workflow variability in Turkish construction projects, an area with limited prior research. By organizing the causes into clear and actionable categories, the findings offer practical guidance for minimizing variability and enhancing project performance. In particular, the results highlight the critical role of resource management in achieving workflow stability. This research contributes to both academic knowledge and industry practice by presenting a structured framework for understanding and addressing workflow variability in construction.
