A computer-implemented method and system for assessing schedule performance issues of a project. A Behind Schedule Performance Index (BSPI), an ahead/behind trend graph, a behind schedule report or an ahead of schedule report is generated. The BSPI excludes an ahead of schedule component from the project's scheduled performance index. The ahead/behind trend graph has ahead of schedule and behind schedule indicators indicating that a portion of the project is behind schedule while the project, as a whole, is ahead of schedule. The behind schedule report filters out ahead of schedule tasks and includes only behind schedule tasks. The ahead of schedule report filters out behind schedule tasks and includes only ahead of schedule tasks.
