Legacy systems are those corporate systems, programming languages, applications, processes, and computer technologies that have stopped receiving upgrades. Notwithstanding their diminishing importance to the outside world, they are an integral part of the corporate processes. In this article at Randed, know the 5 challenges that legacy systems throw if you run them for too long.
Why Run Legacy Systems at All?
While talking about legacy systems, people narrow their scope to old computer systems. Running an older version of an application without an upgraded software license can make it obsolete. The following are the factors why companies still use old systems:
- The company is yet to reach the break-even point for the legacy systems.
- Majority of these systems are customized and support critical business functions and processes.
- Updates of those systems can cause data loss. This gives rise to risks that can hinder your company’s progress.
- The company has built some business rules that have not been documented anywhere and are hard to replicate in a new system.
- People fear that the newer versions might not work as well as the older counterparts.
- The new operating systems, browsers, or networks do not support or are compatible with the legacy systems. Moreover, the systems turn unpredictable over time.
- The hardware, programming language, operating system, or the application stops working eventually.
- Though you provide training, different departments use them for different purposes. Nobody realizes the legacy system’s full potential and hardly anyone documents the use cases.
- Patches increase the risks of security breaches. Numerous faults erupt since the vendor company has stopped upgrading and maintaining the legacy systems.
- While performance decreases, resource consumption increases along with frequent failures. This hampers company yield and work.
