The distribution of tasks in workflow systems is not a trivial problem. There are two solutions to make this distribution: Push and Pull. These solutions, in general, do not consider the resources aptitude. However, resources that share the same role in the workflow can have different degrees of aptitude to a task. The literature in workflow points the solution based on Pull mechanisms with resources aptitude as ideal to tasks, resulting in a more accurate executions and with more quality. This work shows that, if the resources aptitute is used, the solution based on Push presents a better performance and allows a more tuned balancing, regarding to time and quality of the execution of the business processes. The experiments demonstrate the effectiveness of the used approach. A comparison with traditional solutions shows gains in terms of time and quality of tasks execution.
