Requirement Reprioritization: A Multilayered Dynamic Approach

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.
