In this paper we propose a path to guide software development organizations, who are seeking continuous improvement, for developing high-quality software. The process improvement path was established carrying out a similarity study among models and standards related to software requirements development. This study allows us to establish similarities and to determine the most useful aspect of one or more models and standards. The similarities can support software development organizations to achieve the implementation of efficient requirements development process. © Springer-Verlag Berlin Heidelberg 2014.
