What is Tier 0, 1, 2 & 3 support?
Generally, support queries are categorised into tiers according to the nature and complexity of the support query. The tiers loosely correspond to the nature of specialised skills needed to resolve (or fix) the issue.
The follow table provides an overview of support tiers and some examples.
