Many software development organizations suffer from losses. One of the major reasons for these losses is failure of the software projects which is due to improper software project scheduling. Software project scheduling is thus one of the important activities of software development lifecycle which needs to be done efficiently in the beginning of software development. Of late many nature inspired techniques have come to use in software development lifecycle. Particle swarm optimization is one such technique. This paper concentrates on the importance of project scheduling and the use of particle swarm intelligence to schedule the project tasks.
