These organizations and others have identified that in order to increase their agility, reduce spend and balance their two speed IT, modernization is an imperative.
A modernization exercise need not only be about ‘out with the old and in with the new’, it can also involve a rethinking of processes and more efficient ways of accomplishing the present by continuing to redirect technology spends towards growth and innovation instead of run and maintain. The benefits are further amplified if the overall architecture is simplified and supports agility, interoperability and integration. Abstraction and federation are also alternatives while dealing with legacy in a service tiered architecture – more complex initially but can allow a modernization exercise to happen in smaller steps.
Any modernization exercise requires careful planning, architectural review and risk mitigation. It is generally a multi-year exercise and needs to be adequately budgeted for. It does not always include implementation of entirely new platforms but can happen and must be accounted for in the planning.
