Summary

It is time for a major shift in the top-level design model for applications. Model-view-controller (MVC) has been the dominant framework for tying together the user interface and business logic of an application. But flexible, process-focused applications, now and in the future, require a new top-level design model, which Forrester calls Process-Views-Services (PVS). MVC is a programming framework focused strictly on application design for application flexibility. PVS is both a conceptual model for solutions portfolio and an application framework focused on business design and business flexibility, built on a foundation of application flexibility. MVC will still be useful within individual applications, but to increase their focus on business results, architects should move PVS to the center of their application strategies and reorient their conceptual models, architectures, platforms, and planning processes around PVS.
