REDUCE TCO AND OPERATIONAL RISKS BY PHASING OUT LEGACY APPLICATIONS
Application Retirement is the only realistic way in which vital information that has to be preserved
can be stored in a centralised, easy to integrate, archive.
Why should old applications and information stores disappear and be consolidated?
Thanks to application retirement there is a significant reduction in the cost of licenses, maintenance, platform maintenance, and the data-center costs. This effect can be directly measured by adding up the license, maintenance, hardware, OS costs, etc. that are linked to the old applications.
The operational cost of the application landscape in an organization increases as its complexity increases. The reduction of the number of applications and information sources provides for a simplification of the environment and hence for a decrease of the operational cost. This effect is however indirectly measurable. The profit hides in the reduction of time spent on it by system managers, helpdesk employees, application managers, and other stakeholders.
The operational risks in information management increase with the number of applications. The reduction of the number of applications results in a decline of the risks. This is certainly the case with older applications where the knowledge disappears when the staff leaves and retires. The effect is here also indirectly measurable as the benefit is hidden in the reduction of time spent by IT and Application staff. But, as is often the case, the benefit can statistically be measured over the middle to long term.
Phasing out of old applications enables staff to focus on present and future applications that are important for the operation of the business. Keeping old applications alive (or being compelled to do so) is a hindrance. The benefit for the organization is again indirectly measurable but involves reduced man-hours of IT and Application staff. The subsequent enhanced motivation is a solid bonus.
