An introduction to the IBM Views and Viewpoints Framework for IT systems

In 1995 Philippe Kruchten of Rational Software Corporation published his now famous paper, The "4+1" View Model of Software Architecture. The paper presented a model for describing the architecture of software-intensive systems based on the use of multiple, concurrent views which allowed the concerns of various stakeholders of the architecture to be addressed. Since the publication of that paper many of its ideas have been incorporated in development processes such as the IBM® Rational Unified Process®, and standards, such as the IEEE 1471 - Recommended Practice for Architecture Description of Software-Intensive Systems. In this paper we describe how the ideas put forward by Philippe Kruchten have been advanced in IEEE 1471 and subsequently incorporated into a new framework for describing systems based on the concepts of views and viewpoints.
