Due to the competitiveness of the software industry a more stressful tasks for software project managers allocation of the human resources to the different tasks that perform the project. This is not an easy task and it is necessary that is computationally supported since every day projects are larger and these should be developed in the shortest time and possible costs.We propose to use a constructive metaheuristics called IntelligentWater Drops. In this paper the result are compared with another constructive metaheuristics obtaining promising performance.
