What is support in IT?

Support covers the practices and disciplines of supporting the IT systems/applications which are currently being used by the end users.  A production/Application support person/team is responsible for monitoring the production servers or application services, scheduled jobs, incident management and receiving incidents and requests from end-users, analysing these and either responding to the end user with a solution or if it involves change, request will be assigned to development team for the fix and revert to the end user with the resolution.

Generally, there are 3 levels of support in IT: Level 1 (L1), Level 2 (L2), and Level 3 (L3). L1 is the first line of support that involves engaging with clients, knowing their challenge, and creating tickets against it. L1 team/person needs to have basic knowledge of product/service and ability to troubleshoot basic or basic problems. If more access or technical skills are needed to fix the problems, depending on the type of problem, then they can escalate such cases to L2 or L3 support team.

L2 support handles the tickets that L1 routes to them. They have more skills, more experience in solving complicated problems relevant to them and can guide / help L1 support people to work in troubleshooting. Any of the technical problems that require server back-end access can be solved by them. If there are problems that they cannot fix or if there are problems that need further access, then they typically escalate the cases to L3 support team.

L3 is the last line of support and typically consists of a development team that deals with technical problems. They are experts in their profession and manage the most complex issues. They alter the code, study, and improve the solution to challenge new or unknown problems.
