An analysis of software requirements prioritization techniques: A detailed survey

Requirements prioritization is a crucial part of software engineering which helps to make good decisions regarding project planning and implementation with preferred requirements for single and multiple releases. This phase prioritizes requirements for high quality software. Ranks to requirements are assigned according to their importance and are placed in priority list for implementing them in successive releases of the project. Requirements prioritization decisions are made by the stakeholders and the parameters to be considered while prioritizing requirements are risk, cost, importance, etc. Right requirements are considered a part of good quality software. Due to budgetary constraints and time to market deadlines it is essential to prioritize requirements. There are various techniques available to support this prioritization process. The efficiency of these techniques depends upon many parameters that need to be addressed during prioritization process. The goal of this paper is to present systematic literature review of ten requirements prioritization techniques. A comparison of these techniques is also presented on the basis of following parameters: time, ease of use, number of comparisons, scalability and accuracy.
