Definition of a Systems Integrator
A systems integrator (SI) is an individual or business that builds computing systems for clients by combining hardware and software products from multiple vendors. Using a systems integrator, a company can align cheaper, pre-configured components and off-the-shelf software to meet key business goals, as opposed to more expensive, customized implementations that may require original programming or manufacture of unique components. Creating these information systems may include designing or building a customized architecture or application, integrating it with new or existing hardware, packaged and custom software, and communications infrastructure. Some systems integrators working in specialized areas, like SAP installations or upgrades, may offer more customization for specific applications.
