Requirements prioritization and using iteration model for successful implementation of requirements

Abstract

Requirements prioritization is ranking of software requirements in particular order. Prioritize requirements are easy to manage and implement while un-prioritized requirements are costly and consume much time as total estimation time of project can exceed. Because all requirements are depended on each other so total estimation time exceed when requirements wait for pre-requisite requirements. Priority of requirement also increases when other requirements wait for it but assigning low priority to needed requirements will delaying the project. Iteration model is software engineering (SE) process model in which all requirements are not developed at one time but are developed in phases. Only sufficient information or sub-requirements of particular user requirement (UR) can be needed for other user requirements (URs) so by implementing only the sufficient requirements in first phase will reduce waiting time. Hence total estimation time of the project will also reduce. In this research work, iteration model approach is used during prioritization to reduce total estimation time of project and to assure timely delivery of project. From the results it is concluded that not all sub-requirements of particular UR get same priority, but there are only few requirements that are important and should be given more priority.
