On-site IT support is the ability of an organization or company to have physically-present IT technicians at the work or job site. There are times when remote support is just not enough. When PCs go down, when printers break, when network hardware malfunctions, an on-site IT support person can diagnose the problem and find the lowest-cost solution to the performance issue. IT technicians can also diagnose problems with software applications, provide basic user training in how to interact with the corporate computer systems, and generally troubleshoot user issues with the hardware or software at the business location. The company can maintain a central IT support office, and dispatch technicians to whichever office or building is reporting a problem. Small companies are often able to have on-site IT support by having a single IT person, or a tiny group of IT people, on staff.
