# Introduction  This document describes the work made during the _Tópicos Especiais em Engenharia de Software 2_ course. This course was taught by Dsc Claudia Werner and was hold during the second period of the 2015 PESC academic year. The work was a continuation of the research started during the _Reutilização de Software_ course (also taught by Dsc Claudia Werner during the first 2015 academic period).\cite{26243460}  The initial research was mainly about **Software Processes Composition**. It involved, among other tasks, a basic literature review and produced a document that shows some important related articles and describes some problems that we believe that are related to the Software Processes Composition. In contrast with the first research - that involved a more theoretical investigation - the work described in this document had a more practical aspect. It consisted, among other things, in the implementation of an API that provides some operators for Processes Composition and Processes Tailoring. These operators manipulate only processes described in BPMN and were firstly introduced by Duran and Pillat. The work also involved the integration of this API with a web application called **ProcessHub Web**.
