Sixteen limitations for five popular requirements prioritisation approaches

Software is an essential commodity that ensures mobile phones to the controls of an aeroplane work. There will always be more requirements for software than there is time and budget to achieve them, hence the need for various prioritisation approaches to decide which requirements to include in the software. There are also constraints for startups, such as small teams and multiple influencers, which must be considered when choosing a prioritisation approach. The wrong approach can waste resources and cause customer dissatisfaction. There is limited research linked to the limitations of requirements prioritisation approaches; however, this research helps to address the research gap. For example, the main contribution identifies 16 limitations associated with five popular prioritisation approaches combined with a framework which identifies the relationships between these limitations. The five requirement prioritisation approaches studied were analytic hierarchy process (AHP), quality functional deployment (QFD), the planning game, binary search tree, and $100 allocation.
