Plan for modernizing enterprise applications with the flexibility required to address continuous change and evolving labor requirements.


Many organizations are still running monolithic, antiquated systems that are rigid and fail to deliver on the digital business needs of today. Flexibility is key as organizations build a digital core with AI and advanced analytics capabilities.

The COVID-19 crisis has reinforced the importance of digital transformation and the central role of IT. Legacy or redundant systems represent both a barrier and an opportunity for urgent rationalization in order to save costs while enabling the digital enterprise.

What: IDC recommends a framework based on capabilities for application modernization. CIOs and IT leaders will learn success criteria and KPIS in 7 critical areas, and walk through key steps in establishing a rationalization framework, processes, governance & priorities. Find the most effective ways to operationalize the roadmap and related processes.

Why: The legacy portfolio of technology and vendors is often redundant but difficult and costly to upgrade, detracting from other more strategic modernization and DX objectives. A capabilities approach focuses on what matters for the business. It breaks down business challenges into digestible entities, removing emotional baggage and targeting outcomes.

How: To undergo the modernization of your applications for the digital enterprise, your organization needs the following steps:

  • Establish metrics that measure the effectiveness of your rationalization program
  • Build your business case for modernizing enterprise applications
  • Establish a process for modernizing enterprise applications
  • Create a roadmap
  • Evaluate Vendors for fit

Successful DX efforts have measurable, achievable and
supported goals, strategy and KPIs
