Unlike the other viewpoint-oriented techniques described here, viewpoint- oriented System Engineering is a framework. for integrating development methods. The approach is intended to address the entire development cycle, hence the name. VOSE was developed at Imperial College,
London in the early 1990s and is well documented in the literature (Finkelstein et al 1992: Nuseibeh et al.). The underlying philosophy of the framework is that software development involves the participation of many experts, in various aspects-of software development and the application area .
Each participant may have responsibilities and concerns which may change
and shift as the software develops and evolves.
