Tiered support is a customer service model that organizes multiple levels of support, allowing companies to efficiently allocate resources and provide personalized attention to customers. This approach involves creating different tiers of support, with increasing levels of expertise and knowledge required for each tier. The first tier typically handles quick-fix issues, while subsequent tiers require more specialized assistance. A tiered support model is commonly used in companies where customer challenges are recurring or common, and where IT or product teams need to be available to troubleshoot specific issues. By allocating resources accordingly, a tiered support model helps ensure that customers receive the right level of attention, allowing employees to maximize their skill sets while providing personalized service.
