Abstract: In this research, the effects of excessive detail in Primavera P6 schedules are explored to minimize project management effectiveness in construction environments. Comprehensive scheduling is a core aspect of successful project delivery, as this study indicates. However, over-engineered schedules can generate unnecessary complexity, exacerbate practical usability, and complicate actual scheduling and maintenance. This paper analyzes industry practices, identifying areas where additional scheduling details bring diminishing returns and negatively affect project outcomes. The results indicate that P6 scheduling is best when the balance lies between being complete and usable, with suggestions for construction professionals to develop schedules that are neither too complete nor too usable.
