IT management is the work of keeping a company's laptops, accounts, applications and servers running for its own employees, and the software that the IT department uses to do it. In this work, the IT department's customers are the company's employees. The industry calls the part that handles employees' requests IT service management, or ITSM. It calls the rest IT operations.
Consider one week at a maker of pumps and motors in Coimbatore, with 1,200 staff. On Monday, a new design engineer joins. She needs a laptop and a dozen accounts: email, the design software, the drawing archive and the leave system. On Tuesday, a sales manager in Madurai cannot connect to the office network from home. On Wednesday night, the server that runs the factory's order system stops responding. Each of these becomes a ticket. A ticket is a logged request with a number, a priority and a person responsible for it.
The first zone is the IT service desk, where every ticket is logged and sent to the right team. Its main product is IT service management (ITSM) software. Common requests, such as a locked account, are now often handled by an AI service desk agent, which resets the password itself. When a technician must work on a laptop, remote desktop software lets the technician control it from another city while the user watches. Many small companies have no IT staff at all. They pay an outside IT firm, called a managed service provider, to be their IT department. That firm runs a managed service provider platform.
The second zone is IT asset and licence management. A company pays for hundreds of applications, licences and subscriptions. Software asset management (SAM) checks the software installed on every machine against the licences the company has bought. SaaS management does the same for SaaS applications, which are rented by subscription and used over the internet. Banks and insurers also keep some of their oldest systems on mainframes, large central computers, which need mainframe software.
The third zone is end-user computing: the devices that employees work on. Each laptop must be set up before its user arrives, kept up to date, locked if it is lost and wiped when the user leaves. Unified endpoint management (UEM) does this. Digital employee experience (DEX) software measures how well each laptop works, so IT can fix a slow machine before anyone complains. Some staff do not keep their desktop on a laptop at all. With virtual desktop infrastructure (VDI), the desktop runs on a server and is streamed to their screen.
The Wednesday night failure shows how these tools connect. Infrastructure monitoring, which watches the servers, raised an alarm. The alarm opened a ticket by itself, and the engineer on duty was called. One more idea joins the three zones. When the HR system records that a person has joined or left, IT creates or removes that person's laptop and accounts from the same record. This idea is explained on the page on the HRIS.
