A Pipelined Approach for Iterative Software Process Model

摘要

In complex scientific projects where the whole system cannot be completely perceived in the beginning, an iterative development approach that follows the functionality to be delivered in parts has become a necessity and an effective way for refinement and risk management. Iterative development in conjunction with software reuse is one of the most promising and practical ways of tackling risks involved in a complex system. In the iterative model the feedback from the stage wise testing at the earliest can be used to improve the final deliverable. In this paper we share our experience with iterative software development in which multiple iterations are carried out in a parallel fashion. Pipelining concepts are employed to have multiple iterations executing concurrently leading to a reduction in delivery time and early diagnosis of risks. We illustrate the use of this process model through an example of an airborne radar application software project. This paper is organized as follows. It starts with introduction dealing with a comparison between waterfall model and iterative model. In the next section we will discuss about the foundations of iterative model, designers journey, validation in iterative development and application of model for airborne applications. The paper also discusses the conclusions at the end.
