Over a course of time, the technology becomes obsolete and this would hinder the productivity of the entire organisation by hindering the agility of the way which the tasks are carried out. Systems/Applications become redundant and complex over a period of time. This would increase the costs in the maintenance as well all reduces the ability of the organizations to deliver the best.
System rationalization/software rationalization helps business stakeholders to streamline the entire system or software application. Removing the unused modules in any system, reducing the complexity of the software or system and minimizing the process flow or interactions between the systems to increase the agility are some of the benefits of System Rationalization.
