System integration

System integration is defined in <a href="/facts/Engineering/RFVg8H3I">engineering</a> as the process of bringing together the component sub-<a href="/facts/System/hmqQ4ASX">systems</a> into one system (an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality) and ensuring that the subsystems function together as a system, and in <a href="/facts/Information_technology/glMzunwe">information technology</a> as the process of linking together different <a href="/facts/Computing/Kghtm9fX">computing</a> systems and <a href="/facts/Software_application/YQuj7Kog">software applications</a> physically or functionally, to act as a coordinated whole.
The <a href="/facts/System_integrator/z7NkflzJ">system integrator</a> <a href="/facts/Data_integration/BU47JR28">integrates</a> discrete systems utilizing a variety of techniques such as <a href="/facts/Computer_network/3w5RM99p">computer networking</a>, <a href="/facts/Enterprise_application_integration/EaXMz4mI">enterprise application integration</a>, <a href="/facts/Business_process_management/w9KHDJSI">business process management</a> or manual <a href="/facts/Computer_programming/QmSsFnu0">programming</a>.
System integration involves integrating existing, often <a href="/facts/Disparate_system/LclKVjIt">disparate systems</a> in such a way "that focuses on increasing value to the customer" (e.g., improved product quality and performance) while at the same time providing value to the company (e.g., reducing operational costs and improving response time). In the modern world connected by <a href="/facts/Internet/Xw1rVvJU">Internet</a>, the role of system integration engineers is important: more and more systems are designed to connect, both within the system under construction and to systems that are already deployed.
