Abstract

Project scheduling has evolved significantly since its inception from fundamental visual tools to advanced systems. This paper traces the methodological progression, beginning with early 20th-century scheduling innovations such as the Gantt chart for task management. The mid-20th century introduced the critical path method (CPM) and program evaluation and review technique (PERT) to identify critical tasks and optimize timelines. Advancements including building information modeling (BIM) and artificial intelligence (AI) which further refined scheduling practices allowing for dynamic project planning and predictive analysis. This paper explores historical developments, technological advancements, and future trends while identifying the needs driving development, demonstrating how the evolution of project scheduling practices has improved project outcomes and efficiency.
