IT support professionals are tasked with ensuring the ongoing operation of IT systems and infrastructure. They use their technical skills to monitor, diagnose and resolve issues that arise within any given system, as well as providing end users and clients with the technical support necessary for decision-making.
Additional duties often include user training, developing and carrying out IT protocols and policies, research into new technologies to ensure their compatibility within existing systems, and establishing countermeasures when required. In many cases they also act as a point of contact between external agencies such as suppliers and other stakeholders.
Consequently, IT support specialists must possess excellent communication abilities alongside their technical knowledge in order to perform their role effectively.
