Basic Requirements Engineering with ReqIF Studio (32 min)


Content: This lecture teaches you the basics of requirements engineering, and how to use ReqIF Studio for this purpose. You learn what requirements are, why tools are necessary, and how a development process could look like. You learn what attributes are recommended, and how you add them in ReqIF Studio. You learn how to use traces, and how to perform some basic analysis.
