1. How do you define and measure service levels?

Service level agreement (SLA) is an essential aspect of any service delivery agreement between a customer and a service provider. To define and measure service levels, I always start by identifying and agreeing on service level targets with my team and our clients. Once the targets have been established, we use metrics to measure our performance against the targets.

  1. First, we establish clear service level objectives, and we ensure that the objectives are specific, measurable, attainable, relevant, and time-bound (SMART).

  2. After that, we set up a monitoring process that is designed to track our performance against the objectives. This process enables us to identify and address any shortcomings promptly.

  3. We communicate regularly with our clients, and we provide them with progress reports showing how well we are meeting our service level targets. Regular communication helps to build trust and ensures that our clients are satisfied with the level of service being provided.

  4. We also track and analyze data on the service levels we provide. For instance, if we have set a target to respond to customer inquiries within 24 hours, we track the number of inquiries we receive, the number we respond to within 24 hours, and the number we respond to beyond 24 hours.

  5. In analyzing these data, we can identify trends and patterns that we can use to improve our service levels. For example, we might find that we are receiving a significant number of inquiries after hours, and we can adjust our staffing to provide more coverage during those times.

  6. We also conduct regular service reviews with our clients to get their feedback on our service levels. These reviews help us to identify areas where we can improve and enhance the service we provide.

In summary, defining and measuring service levels requires establishing clear objectives, setting up a monitoring process, analyzing data, and communicating regularly with clients. By using these steps, we can ensure that we are meeting our service level targets, and we can continuously improve the services we provide.

2. What experience do you have in negotiating and meeting SLAs?

Throughout my career, I have gained extensive experience in negotiating and meeting SLAs. In my previous role as a Service Delivery Manager at XYZ Company, I was responsible for negotiating and managing SLAs with multiple clients.

I consistently exceeded SLA targets, resulting in a high level of client satisfaction. For example, I negotiated a contract with a leading financial institution that required us to provide a 99.9% uptime guarantee for their critical applications. I was able to negotiate favorable terms that granted us a reasonable outage window, while still meeting their stringent performance requirements.

In another instance, I identified an opportunity to renegotiate the SLA with a major healthcare client. By proposing a revised SLA that aligned better with our resources, we were able to decrease incident resolution times, and ultimately, secure a contract renewal. As a result of my efforts, our client reported a 20% reduction in downtime and an overall satisfaction score of 9.5 out of 10.

Overall, my experience in negotiating and meeting SLAs has been instrumental in delivering high-quality services and maintaining strong relationships with clients.

3. What methods do you use to monitor and track service level metrics?

At my last job, we used a combination of monitoring tools and manual tracking to keep track of our service level metrics. One of our main tools was a monitoring software that we implemented to keep track of our website's uptime and response time. This software would send alerts to our team if there were any issues detected or if our response times started going over our designated SLAs.

  1. We also tracked our metrics manually through spreadsheets, which allowed us to keep track of our metrics over time and identify any trends or issues. We would record our response times for each hour of the day, as well as during peak hours and after any major changes to our website.
  2. Another method we used was to set up regular audits of our customer service interactions. This allowed us to see how well our team was meeting our SLAs and identify any areas where they needed additional training or support. During these audits, we would review call recordings and chat transcripts to look for areas where we could improve our response times and customer service skills.
  3. We also kept track of our SLA performance by regularly reviewing customer feedback and surveys. This helped us identify any areas where customers might be experiencing issues that we weren't aware of and allowed us to address these issues quickly and effectively.

Overall, our combination of monitoring tools and manual tracking allowed us to maintain a high level of SLA performance and provide our customers with the best possible service. As a result, our customer satisfaction rates increased by 15% over the course of a year, and our SLA compliance rate rose to 98%.

4. Can you give an example of how you have resolved SLA violations in the past?

Yes, I can give you an example of how I have resolved SLA violations in the past.

  1. Identified the issue: First, I determined the root cause of the violation. It turned out to be a technical glitch that was causing a delay in one of our critical systems.
  2. Assessed the impact: Next, I evaluated the extent of the damage caused by the delay. The report indicated that there was a 10% dip in customer satisfaction ratings due to the delay.
  3. Involved everyone: I then engaged all relevant teams to investigate and resolve the issue. I notified the stakeholders both internally and externally about the situation and gave them updates in real-time.
  4. Implemented solution: After identifying the problem and working with the team to develop a solution, we implemented a code fix within a day. We also ensured that we monitored the system continuously to prevent future incidents from happening.
  5. Measured the results: After implementing the fix, we were able to get back to our previous performance level within a week. Additionally, customer satisfaction ratings returned to their previous level, indicating that we had handled the situation satisfactorily.

In sum, I am confident in my ability to resolve SLA violations while minimizing the impact on the end customer.

5. What steps would you take to prevent potential SLA breaches?


  1. Set and Review Clear Expectations: It is crucial to set clear expectations for customer service by deciding which metrics will be used to measure success. This includes discussing what metrics will be measured, how often they will be measured, and what performance levels are expected to be achieved.
  2. Regular Client Communication: Maintaining open lines of communication with the client is important to prevent SLA breaches. Regularly scheduled meetings and reporting keeps clients abreast of the progress made in meeting their expectations. If the client is aware of your progress, they will have a better understanding of what to expect and if timelines need to be adjusted.
  3. Implement Escalation and Notification Systems: Define escalation procedures and outline the steps needed to notify everyone involved in the event of an SLA violation. An effective escalation process ensures that any issues are quickly identified and resolved before they become bigger problems.
  4. Ensure Continuous Process Improvement: Regular reviews, data analysis and identifying areas to automate or eliminate is necessary to maintain healthy SLAs. When potential time drains are removed, team members can spend more time proactively preventing breaches as opposed to reacting to them.
  5. Implement Service Quality Management Tools: Utilize software or systems that aid in monitoring SLAs. By using dashboards configured to monitor predetermined metrics, stakeholders can receive real-time updates of service quality, performance and compliance. This ensures that service level objectives are always at the forefront of employee's decisions. This can also prevent breaches and allows for quick mitigation in the event of a breach.

As a team lead in my previous organisation, I implemented these steps and was able to reduce SLA breaches by 60% over a period of 6 months. In addition to these steps, I was also able to come up with a service improvement plan which resulted in the retention of 80% of our clients.

6. Can you describe your experience with incident management in relation to SLAs?

During my time as a Service Delivery Manager at XYZ Company, I was responsible for ensuring that all incidents were resolved within the agreed SLAs. My team and I developed a robust incident management process that allowed us to effectively monitor and respond to incidents in a timely manner. As a result, we consistently achieved SLA compliance rates of over 95%.

  1. Firstly, we created a classification system for incidents, which allowed us to prioritize response times based on the severity of the issue. This ensured that critical incidents were addressed as a matter of priority.
  2. Next, we established clear communication channels between our team, our clients, and any third-party vendors or suppliers involved in the incident resolution process.
  3. We used a ticketing system that automatically triggered alerts as soon as SLAs were approaching or breached. This allowed us to take proactive measures to prevent SLA violations and kept everyone involved informed and up-to-date on the status of the incident.
  4. In addition, we regularly reviewed our SLAs and incident management processes to identify areas for improvement. This resulted in a continuous improvement cycle that allowed us to optimize our processes and reduce incident resolution times.

To provide a specific example, we had a client that had experienced several instances of network downtime, which was causing significant disruptions to their business operations. We worked with our network team to identify the root cause of the issue and implemented a solution that reduced the downtime by over 50%. This led to an improvement in our SLA compliance rate for that client, which had previously been around 80%, to over 95%.

7. How do you prioritize support tickets in relation to SLAs?

As a support team, we aim to ensure we meet our SLAs whilst delivering excellent support to our clients. Firstly, we prioritize tickets based on their urgency level and how this aligns with our SLAs. For example, if a client is experiencing an issue that is causing an impact to their business operations, we would prioritize this over a general inquiry.

Secondly, we consider the SLA timeframes and the past performance of meeting them when prioritizing tickets. If we have a high percentage of tickets that have been resolved within the agreed timeframe, we will prioritize tickets that have a shorter time remaining on their SLA.

  1. Impact on business operations
  2. SLA time remaining
  3. Past performance in meeting SLAs

We also take into account the client's severity rating. Clients with a higher severity rating receive faster support, as their issues pose a bigger threat to their business operations. This helps us ensure our support is focused where it matters most.

Our prioritization process has allowed us to consistently meet our SLAs whilst providing exceptional support to our clients. In fact, our team's average resolution time has improved by 20% over the past year, resulting in a 95% SLA compliance rate and an overall increase in customer satisfaction.

8. How do you communicate SLA status and updates to stakeholders?

As an experienced SLA professional, I understand the importance of effectively communicating SLA status and updates to stakeholders. To achieve this, I follow a few key steps:

  1. Establish regular communication channels: I schedule regular check-ins with stakeholders to discuss SLA performance and provide updates on any changes or developments. This includes setting up weekly or monthly calls, emails, or reports.
  2. Provide clear and concise reports: When communicating SLA updates, I ensure that the reports are easy to understand and include all relevant data points. These reports should include SLA metrics such as average resolution times, percentage of tickets resolved within SLA, and current status against target performance.
  3. Address concerns proactively: If SLA performance is not meeting expectations or there are concerns from stakeholders, I take a proactive approach to address these issues. This involves investigating the root cause and developing a plan of action to improve performance. Moreover, I communicate this plan to stakeholders and discuss how we can resolve the issue.
  4. Celebrate successes: When the team achieves SLA targets or makes significant improvements in performance, I ensure to share the good news with all stakeholders. This helps to motivate the team and demonstrates to stakeholders that their investment in SLAs is yielding results.

By following these steps, I am confident that I can effectively communicate SLA status and updates to stakeholders, enhancing the overall effectiveness of our SLA program. For example, in a previous role, I was able to reduce the average resolution time for tickets by 30% over a quarter, by communicating regularly with stakeholders on the performance and identifying areas for improvement to achieve the result.

9. What tools and technologies have you used to manage SLAs in previous roles?

In my previous role as a Service Level Manager, I was responsible for ensuring that our SLAs were met consistently. To achieve this, I used a variety of tools and technologies:

  1. ServiceNow: This platform acted as the central repository for all our SLA-related data, including contracts, performance metrics, and escalations. It helped me maintain visibility across all service lines and allowed for rapid identification of any trends or issues.
  2. Automation: Through the use of scripts and macros, I was able to automate many of our SLA monitoring processes. This eliminated human errors and ensured that alerts were raised immediately in case of any deviations from our agreed-upon SLAs.
  3. Reporting analytics: By using tools like Tableau, I was able to create dynamic dashboards that showed real-time data on our SLA performance. This helped me to identify areas of improvement and to communicate our progress to stakeholders.
  4. Internal benchmarking: To gain a deeper understanding of our performance, I used internal benchmarking techniques. By comparing our SLA data against that of similar companies in our industry, I was able to identify areas where we excelled and where we needed to improve.

Using these tools and technologies, I was able to improve our SLA performance significantly. Our average resolution time decreased by 30%, and our SLA compliance rate rose from 85% to 95%. This resulted in a boost in customer satisfaction ratings, with our Net Promoter Score increasing by 15%.

10. What do you think are the most important components of a successful SLA?

For me, there are three key components that are essential for a successful SLA:

  1. Clear and measurable objectives: Without clear goals, it's difficult to determine whether the SLA has been successful. The objectives should be specific, measurable, achievable, relevant, and time-bound (SMART). For example, increasing customer satisfaction rates by 10% in six months.
  2. Realistic targets and deadlines: The targets and deadlines set within the SLA should be realistic and achievable. This ensures that both parties involved are set up for success. Targets that are too ambitious can lead to frustration and unrealistic expectations, while targets that are too low can hinder growth and progress. For instance, a goal of resolving 90% of customer complaints within 24 hours could be attainable, while resolving 99% in one hour may be unrealistic.
  3. Effective monitoring and reporting: Monitoring and reporting are essential to ensure that both parties are meeting their obligations. This component comprises of performance metrics, regular reports (weekly, monthly, or quarterly), and corrective measures. Robust monitoring and reporting processes make it easier to track progress and identify areas that need improvement. For example, monitoring ticket closure rates, response times, and customer feedback scores can help to ensure that the SLA objectives are being met.

In summary, a successful SLA requires clear and measurable objectives, realistic targets and deadlines, and effective monitoring and reporting. These three components working together can help to achieve positive outcomes and ensure that the partnership remains intact. As an example, my previous company implemented an SLA with one of our major vendors and saw a 25% increase in on-time delivery rates within the first quarter of implementation.
