In this paper, we present the application of a set of software engineering roles. Role definitions were developed using internationally recognized software engineering reference documents for a major railway development organization: Bombardier Transportation. The description of the Software Architect role is explained. This paper will also illustrate how the role set could be used for project-specific needs during a typical project planning and launch session.
