KPIs of Each Tech Support and Help Desk Tier

As the general service scope and expertise of all tier-based support levels are vastly different, support managers have set different parameters to monitor their performance and rate them. The key logic behind these different rating and performance metrics is to ensure all service agents are judged based on their level of expertise and support complexity. Besides, there’s also an aspect of which metrics matter more at which level. Handling times would matter more at T1, where issues are simpler and a faster resolution rate is expected. Whereas for L2, the escalation rate matters more.

L1 Key Performance Indicators

  • First Call Resolution (FCR): The FCR indicates the proportion of inquiries resolved during the initial interaction with L1 support personnel.
  • Average handling time (AHT): The handling times denote the speed at which IT support teams resolve an issue, including the initial contact to resolution or escalation.
  • Ticket volume: The total volume of tickets to assess the rate of resolution and overall workload on L1 support personnel within a specified period.
  • Customer Satisfaction Scores (CSAT): CSAT gauges client feedback regarding their interactions with an L1 support agent.
  • Service Level Agreement (SLA) compliance: An SLA outlines the agreed-upon terms between a business and its customer. It exhibits how frequently the L1 agents resolve issues within the predefined timeframes.

L2 Key Performance Indicators

Including the KPIs of L1 agents, the performance of L2 agents is also measured based on these parameters:

  • Knowledge utilization: This term refers to how effectively L2 specialists apply their expertise and utilize all internal resources available to them. A low utilization rate may indicate the presence of departmental barriers, insufficient technical knowledge, or incorrect operational procedures.
  • Customer retention: Your retention rate measures the percentage of customers who continue to use a product or service following the resolution of a technical issue. A high retention rate reflects the quality of issue resolution provided by L2 support.
  • Team effectiveness: Success indicators such as the number of cases handled, average handling time per case, and the ratio of escalated cases determine the efficiency of the L2 team. A successful outcome suggests the presence of appropriate escalation channels, workload distribution mechanisms, and effective knowledge transfer from L1.
  • Escalation rate: This metric compares the number of cases resolved by L2 representatives to the number of cases escalated to L3. A high escalation rate may indicate efficiency issues or the need for additional training, as only a small portion of cases should necessitate escalation to L3.

L3 Key Performance Indicators

  • Mean Time To Resolution (MTTR): MTTR indicates how quickly L3 teams can identify and resolve high-level issues, such as data breaches.
  • Backlog management: As the final line of defense, L3 support may have numerous ongoing cases. Backlog management measures the number of open cases and the overall rate of case completion.
  • Development collaboration: Specialized metrics like enhancement reports reveal the effectiveness of collaboration between L3 support technicians and development teams.
  • Proactive identification: The rate of identifying issues, notifying customers, and proactively defending against threats showcases the diligence of L3 technicians in ensuring a stable customer experience.

Before and Beyond L1-L3 Support

L1-L3 are the most common tech support tiers, but constantly evolving customer demands, CX trends, and tech innovations are opening new possibilities for customer engagement. To this end, it’s critical to ensure that the scope of your tech support and help desk is not limited to T1-T3. AI innovations are having a transformative impact to enhance these support functions. Let’s explore what lies beyond L1-L3 help desk support.  

Tier 0 – Self-Service

CX today isn’t just about delivering quality support whenever a customer contacts. It’s also about enabling customers with proactive and ever-present support, irrespective of your support team’s availability. Self-serve options such as FAQs, customer forums, chatbots, and IVRs have existed for a long time to address this. With the latest AI innovations, these can elevated to the next level. 

Self-help and user-retrieved information from webpages or apps, including FAQs, detailed product and technical information, knowledge base articles, blog posts, user manuals, and search functions, enable the users to get help without involving IT staff. Customers also use emails, customer forums, and social media platforms to contact support. Level 0 support saves valuable time for more experienced technical specialists, allowing them to focus on more complex tasks and decrease call volumes.

At this level, customer-to-employee interaction is minimal or nonexistent. It also increases agent satisfaction who do not have to interrupt their work to answer phone calls constantly. A major chunk of the staff requirements is needed to design, develop, and maintain webpages and apps. Some marketing and support professionals engage with customer forum moderation or communication through email or social media. A few personnel are needed to classify and filter requests based on complexity and improve routing, but that can be automated with the latest AI solutions. 

Tier 4 – Outsourcing

Tier 4 support serves as an external resource for addressing issues beyond the scope of internal support within an organization. This level of support typically involves contracted assistance for items or services not directly managed by the company, such as printer support, vendor software assistance, machine maintenance, and other outsourced services. When problems or requests arise in these areas, they are forwarded to Tier 4 support for resolution, with the organization overseeing the implementation process.

Preferred vendors and business partners are often engaged to provide specialized support for the products or services offered by the company. Tier 4 support is particularly relevant in scenarios where a parent organization outsources services, requiring external technical expertise that the company does not directly provide. Specialists at this level may also play a role in refining products to enhance their functionality and performance.


The tier-based tech support emerges as a cornerstone in ensuring seamless operations within organizations. By structuring support teams into distinct levels, companies can efficiently manage the complexity of technical issues, ensuring swift and effective resolution at each level. This tiered approach not only optimizes workflow and resource allocation but also enhances the overall CX by providing specialized assistance tailored to the specific needs of users.

Outsourcing tech support can effectively streamline operations and access specialized expertise. By partnering with external service providers such as Vsynergize, organizations can tap into a vast pool of technical knowledge and resources, often at a lower cost than maintaining an in-house support team. Outsourcing also offers scalability, allowing companies to adjust support capacity according to fluctuating demand without the overhead of hiring and training additional staff.

In today’s fast-paced business environment, where downtime can have significant repercussions, tier-based support and outsourcing stand out as indispensable strategies for maintaining operational efficiency and delivering exceptional customer service. By embracing these approaches, companies can stay ahead of the curve, ensuring smooth sailing even in the face of technical challenges.
