Modernization Approaches

IAI provides its govenment and commercial clients with a variety of alternatives for modernizing their legacy systems. Each of these legacy modernization approaches ensures maximum reuse of the unique logic created and maintained by organizations at the heart of their operations, while incorporating new technologies that enable new functionality to be added quickly.

Current Situation	Business Need	Modernization Solution
Traditional client server or non-graphical user interface.	Provide Internet or Intranet access to legacy systems functionality.	Web-enabled Legacy Interface
Limited ability to add new functionality.	Extend applications to customers and add functionality over the Internet.	SOA-based Legacy Extension
Legacy systems have little or no integration with other systems.	Integrate legacy systems easily with other systems internally or externally.	Application Integration
Aging or proprietary hardware and software environments.	Reduce total cost of ownership for legacy system functionality.	System Migration
Limited qualified and available resources to work on legacy systems.	Changes in business rules require adding, modifying and sustaining functionality more easily.	Application Development and Support
Multiple, disparate systems, which may still contain unstructured code.	Reduce the number of different operating environments and structure the systems to ease support.	Consolidation and Remediation
Systems are insufficiently documented; unclear plan for sustaining operations.	Inventory legacy system applications and databases; identify interdependencies and plan modernization actions in legacy environments.	Legacy Portfolio Assessment
