Why and How to Set up a Tier 4 Help Desk
The tier 4 help desk is the final layer in the 5 levels of IT support. Its main purpose is to effectively handle incidents for services that the organization has outsourced. This means that tier 4 support handles everything by tiers 0 to 3, but this time the work is carried out by a third-party help desk. Tier 4 support is typically used when it is not possible to have the required support knowledge in-house or if third-party support is needed at a contractual level, for example, to maintain a warranty.
