Business Process Management Systems (BPMS) are the basis for a process-based approach that combines information technologies with process methodologies and governance to create more efficient software systems to the reality of business today. The evolution of these BPMS involves at least four well-defined waves since the '80s. There is a consensus that the fouth of these waves has not yet happened and that it will be the next generation of business process management systems. This article presents a brief description of a typical BPMS technology architecture and describes the evolutionary process of these systems in terms of major technology waves and their main characteristics. It presents a survey of what the main experts in the field believe that should be present in the new generation set the fourth wave and discusses what needs to be modified in typical technology architecture so that it is compatible with the new wave described. At the end of this analysis, it was observed that most of these characteristics envisaged for the new generation is already available and in use, in a timely fashion in various commercial systems that are considered systems the transition between the third and fourth wave.
