An efficient process model for distributed software application developments

One of the problems we face today for software development is how we can comply with the speed of change in the business environment. To address the issue, we present a new paradigm called Progressive Development Model that gradually releases the software components according to the current business needs. In this paper, we also present a design pattern of software architecture optimized for Progress Development Model. Under the design pattern, system functionalities are identified into two components: Core and user functions. With a standardized interface called AIL, staged user functions can be attached onto the core without breaking or deforming the overall architecture. The development model is especially suitable for the distributed software applications development that is getting its popularity recently.
