Resumen
Many of the organizations often fail to deliver big size software projects in allocated time and budget. One of the main reason of exceed in time estimation is improper implementation of requirements and their integration as software requirements are inter-related and thus waiting time of requirements for their pre-requisite requirements can delay whole project . As compare to small size software?s, requirements of big size software systems such as Enterprise Resource Planning (ERP) are normally implemented by parallel and distributed team members so prioritization of requirements become necessary in parallel development for timely delivery of whole project. In this research work, AHP is efficiently applied to prioritize software functional requirements with minimum time complexity. Differences in time estimation without prioritization and with prioritization shows significance of prioritization with AHP.
