Modular, layered architecture: the necessary foundation for effective mass customisation in software

Abstract

This paper posits that developers cannot sustain extensive customisation of software without clear software product line architecture, modular subsystem platforms, and disciplined interfaces among these platforms. To explore this proposition, we initially define the basic principles of desirable software architecture and then apply these definitions to the development of software and the business strategy for creating software product lines. We then illustrate how these concepts not only explain the success of leading software companies but also have motivated fundamental architectural redesigns of their product architectures.
