This article approaches the improvement of the software development processes specified with the Software Process Engineering Metamodel version 2 (SPEM). The work consists of transforming the SPEM specification of the SmallRUP development methodology to be used as an input of a Standard Workflow Engine. For this purpose, a transformation was used defined in Relations language, which is part of the Query/Views/Transformations (QVT). Such transformation has been specified in former research works and converts a SPEM specification into a process specification in Business Process Modeling Notation (BPMN). The BPMN specification is the base to specify with the process editor of Bonita tool, the business process that represents SmallRUP, and this way, manage with a Standard Workflow Engine, included in Bonita, a development project that is managed following the SmallRUP methodology.
