Today, government IT teams are expected to deliver more services with fewer resources. Consequently, many agencies have prioritized legacy modernization, interoperability and shared service models as a means towards increasing IT delivery capacity. But those approaches are easier talked about than executed. As agencies embark on legacy modernization, it becomes imperative to open up the existing technology so that new innovations can be delivered as needed in a secure way. In this guide, produced in partnership with Govloop, we will discuss a five-play roadmap to help those in government get a better sense of where to start on modernization projects, an overview of the Information Technology Modernization Fund (ITMF), featured government success stories highlighting their modernization projects, and the IT Modernization Lifecycle, based on the recent report by the American Council for Technology-Industry Advisory Council.
