Modeling Software Development Processes

Information and Communication Technology (ICT) has become the no. 1 business driver of economy and the key to practically all human activities. The ongoing reduction of the size and the cost of computers together with increased speed and performance allows the implementation of functionalities completely unimaginable even a decade ago. This creates a demand for more software with higher sophistication and with higher quality. Additional requirements are shorter time-to-market together with flexibility and adaptability fo software with respect to answering user needs. Since approximately 1970 (Royce, 1970) it is understood that the development of a software system is a multi-phase process. Each phase is concerned with contributing a different view and focus of the software artifact to be produced. In order to guarantee an orderly, systematic process this stepwise process should be defined and described AbstrAct
