Abstract

It is necessary for an organization to know when to end the lifecycle of its legacy information system once it is no longer able to accomplish and conform to the modifications the organization needs. Prolonging the length of an information system lifecycle could lead to a decrease in software cost.
Consequently, there is the need to develop an assessment model to determine whether or not to continue with the existing information system. However, most of the various metrics and models presented in literature and the researchers' evaluation methods are qualitative and are evaluated by domain experts subjectively. The results obtained will therefore be imprecise. We adopt a quantitative metrics and model methodology to get a more accurate measurement of legacy information systems. This study developed an enhanced agility assessment model to measure legacy information systems with the agility factors: Speed, Robustness, Complexity and Technical skilled personnel. The developed model will resolve the flaws of the existing metrics and models as a result of the quantitative methodology and objectivity of the proposed mode
