It seeks to reassure organizations about the effectiveness of this strategy, illustrating how it can be harnessed as a pivotal tool for businesses to substantially improve performance, customer satisfaction, and competitive positioning. 


What is Application Re-engineering?

Application re-engineering is not just about software maintenance or incremental improvements. It’s a strategic process that involves rethinking and redesigning software applications to significantly improve their functionality, efficiency, and alignment with current business objectives. It represents a fundamental reworking of existing applications to adapt to new technologies or shifts in business strategy. In fact, a recent study found that around 89 % of companies have already adopted a digital-first business strategy or plan to do so soon, highlighting the strategic importance of this process. It involves several approaches, each with specific scenarios, costs, and associated risks. 


Replatforming moves an application to a new runtime environment with minimal changes to its existing code. It is most applicable when the original application is still of good quality and when the benefits of new environmental features, like enhanced performance and speed, are needed without a complete overhaul. This approach is less costly and risky, making it a suitable option for businesses leveraging modern cloud infrastructures or platforms without extensive redevelopment costs. 

Refactor or Re-architect
