When models collide: lessons from software systems analysis

Sooner or later, the assumptions people make about what a system should do will conflict. Here's how to recognize it before it's too late. Systems analysis is rapidly coming of age. Many projects have successfully used a new approach called MBASE (Model-Based System Architecting and Software Engineering). The MBASE approach integrates the four common development models (success, product, process, and property) around the creation and use of a software architecture package. As analysts explicitly integrate models using MBASE, they can recognize and reconcile model clashes as a matter of course, instead of after the fact.
