Application portfolio management involves thoroughly analyzing an organization's IT applications, systems, processes, and data to identify opportunities to improve efficiencies and reduce costs. Key goals are to eliminate redundant or underutilized systems, consolidate data sources, retire legacy applications, and ensure IT resources are optimized to support business needs and strategy. The process involves gathering details on all applications and systems such as their use, users, costs, business value, and technical requirements to assess which should be maintained, enhanced, retired, or combined. Analysis results provide justification and business cases for prioritizing improvement projects.
