Abstract
Software Process Simulation (SPS) has been evolving in the last decades and gained researchers' and practitioners' interests in software process community. However, the growth of SPS seems slow down in recent years, and the evidence for its benefits to industrial practice is not commonly reported as expected. SPS still awaits a breakthrough success. This special panel aims to initiate a discussion on the challenges faced SPS and the solutions to tackling the problems, and to work out a research agenda for future advance of SPS.
