Tier 3 Help Desk: General Overview

Tier 3 help desk is the highest IT support level within a multi-tiered IT support system. L3 engineers resolve complex infrastructure-related requests and issues (e.g., server virtualization, planning network architecture and configuring network elements) and handle app issues on the code level. 

The scope of the L3 help desk can cover user-facing software, desktops, mobile devices, operating systems, networks, databases, cloud services, back-end configurations, and more.

The team required: a team lead and L3 help desk engineers.

With deep technical expertise backed by 34 years of experience in IT, ScienceSoft helps companies resolve L3 issues, reduce help desk costs by up to 40%, and ensure a user satisfaction rate of over 96%.

Tier 3 Help Desk Setup Plan

L3 help desk launch plan and time frames greatly depend on the maturity and complexity of your IT infrastructure and applications. ScienceSoft has summarized 16 years of experience in IT support and outlined a pathway to establishing efficient help desk processes.

Stage 1.

L3 help desk planning and design

Duration: from 2 weeks
  1. Outline your budget for L3 help desk setup and maintenance.
  2. Create a list of IT infrastructure elements and apps that require L3 support.
  3. Determine what goals you want to achieve with the L3 help desk (e.g., introduce app code changes, implement improvements, migrate to the cloud).
  4. Define the size of your future L3 team, aligned with your budget and scope.
  5. Decide on communication channels (a service portal, email, etc.)

If your company already has an established L1 and L2 help desk, your current support and communication processes must be considered when designing an L3 help desk.
