Systems Integrator is an individual or business that builds computing systems for clients by combining hardware and software products from multiple vendors. Systems Integrators generally have to be good at matching customers’ needs with existing products. It has traditionally been a crucial speciality in the defence contracting industry. 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.
