The reference model of Competisoft is composed of nine processes and a work within the context of the project Competisoft established some validation and verification activities in the process Software Development. Software test tasks are considered in the validation and verification activities, but these activities are not sufficient to define a Software Testing process in the organization which can be efficiently managed, controlled and improved. In this paper, we show how the reference model of Competisoft can be enhanced by adding another process called Software Testing. The main benefit for the organization is the promotion of a better control and management of software test tasks. A real-world case is shown in order to illustrate how an organization can deploy the process and the benefits that arise from that deployment.
