It provides ways to implement the processes and provides functionalities to control and modify their workflows. A very useful tool to achieve this control is a set of process models, as they supply a description of the process structure and complexity. Considering the importance of Business Processes models, the use of metrics may be the key to obtain high quality models that are useful as support to improve the processes maintenance, updating and adaptation. Based on metamodels of the BPDM standard, a proposal of metrics for Business Processes models is submitted; these metrics are specified in OCL and their application results are outlined in a study case. Key words: Business Processes, Metrics, BPDM, BPMN, OCL. I. INTRODUCTION The Business Processes (BP) complexity has led to conduct studies on aspects as usefulness [1], quality assessment [2], measurement [3], and most frequently, on the use of the different modeling tools and languages of BP [4], [5], [6]. Such interest is boosted by the diversity of notations and languages for modeling, defining and executing the existing BP. The Business Processes Models (BPM) have a wide range of uses such as the support to the process re-engineering, the simulation, or as a base for the development of systems that automate such processes. They may be created or presented using several languages that are quite different, as each sees the processes depending on the purpose for which it has been created [5]. Therefore, several proposals may be found in literature, from which UML [7], UML 2.0 [8] and BPMN [9] stand out. From another point of view, [10] gives the definition of the Business Processes Definition Metamodel (BPDM), which provides a serialization mechanism and an explicit metamodel for BPMN concepts. The integration of BPMN and BPDM gives an integrated set of standards that include the subjacent model and notation for the process orchestration . Another important aspect to consider is that the BPMs must be built taking into account their quality regarding maintenance and adaptability to changes that Business Processes experience. For this purpose, it is important to have a way to measure such quality. Therefore, it is of great usefulness the definition and application of metrics at the early stages of the processes development. Likewise, their formal
