Legacy systems are hard to replace and we’ve discussed a few reasons why, above. But the question of whether a move away from them is warranted or not will require a more detailed analysis.
Consider a case when an organization that has been in business for a decade, has a set of trusted vendors and suppliers it engages with. Many-a-times, these vendors and suppliers have their own applications that must be used. At other times customer firms have hosted applications that must be used to supply information. This is vital for the continuance of the business relationship itself. You may find several such cases throughout your supply chain.
Further, legacy systems are packed with functionality that is industry specific and widely useful. You have trained and skilled personnel working on these systems for ages. These instances of systems have been highly customized. And they work effectively. Additionally, they offer differentiation from the crowd.
Other important factors to consider are the cost of switching, as well as the readiness for the technological shift. Right from freeing up resources to training or even hiring personnel, costs can run high.
Working through all these points, if it makes strategic sense to keep the legacy systems running until the very last mile, we should. At the same time, savvy firms will leverage the one tool that will help them continue the business benefits of older systems and advance when the time arrives: RPA.
