Abstract: Scheduling risk is one of the most critical risks of software project. The scheduling risk management based on task critical chain was discussed in this paper. Each task’s duration in ideal working environment was estimated, personnel resource constraints were taken into account, and the project’s critical chain was built. After the risk analysis for each task, the project buffer was established for the critical chain and feeding buffer was established for non-critical chain. The buffer area was treated as resort of risk control and management.

Key words: software project, scheduling risk management, critical chain
