The task of requirement reprioritization is an important activity initiated due to the dynamism in the developing & the working environment of the software. Reprioritization is focused on the re-allotment of priorities to both implemented as well as non implemented ones. Focusing the implemented ones will ensure quality of regression testing and stressing on non implemented ones will ensure to consider the delayed as well as new or changed requirements. The reprioritization is complex decision making and effortful activity. Thus this task will require some heuristic parameters that could lead to the minimization of reprioritization efforts without any negative fabrication of quality of the current version. This paper proposed a multilayered dynamic approach for requirement reprioritization that is well suited for both agile and non agile development methodologies employing any prioritization method. The proposal is illustrated with the help of live case study of Library Management Software System developed in the Computer Programming laboratory of National Institute of Technology, Hamirpur.

The delivery of new increments involves decision makings at various levels like decision aspect prioritization, requirement priorities and selections of regression test cases. The pressure to deliver high quality low cost software by employing limited resources and satisfying mass market invokes the need to have less dependence on regression testing activity. Earlier Proposed requirement prioritization technique categorizes the type of changes and the type of new implementations and then decides the neglection or minimization of test cases. Further minimizations are also possible due to existence of sound regression testing techniques. By focussing on common problems related to the development of mobile and embedded type software applications, one could have great improvement in software development quality and practices. The proposed requirement prioritization technique is applied in evolutionary mobile software application development and results were quite promising. This paper aims to have a deep insight into the ability of the proposed technique in minimization of regression testing of desktop software applications application. The results are very promising thus indicating the usefulness of proposal in low cost development of both mobile compatible and desktop software applications. The novel contribution of this paper lies in making the incremental development timely and low cost activity by making requirement prioritization effective and future increments less dependent on regression testing without having any compromise with the desktop software quality. This had been a result of analysis of proposed prioritization technique on desktop software application.
