1. What is an SLA?
A Service Level Agreement (SLA) is a formal, documented agreement between a service provider and a customer that defines:
- The services to be provided
- Performance standards and expectations (e.g., uptime, response time)
- Metrics for measuring service performance
- Responsibilities of both parties
- Penalties and remedies if the agreed standards are not met
Example:
An IT company may have an SLA with a customer stating that its services will have 99.9% uptime and all critical issues will be resolved within 2 hours.
Key Characteristics of SLAs:
- Measurable and Specific: Must include clear, quantifiable metrics (e.g., 99% uptime).
- Binding Agreement: It is part of the contract between the provider and customer.
- Focuses on Accountability: Defines what happens if service levels are not met.
2. Purpose of SLAs
For Customers:
- Sets Expectations: Customers know what level of service to expect and what compensation they’ll receive if it isn’t met.
- Provides Transparency: Makes the provider’s performance trackable and accountable.
- Reduces Risk: Defines remedies or penalties for service failures.
For Service Providers:
- Defines Scope Clearly: Prevents “scope creep” by clearly stating the services included.
- Helps Prioritize Work: Providers can focus on meeting agreed performance standards.
- Builds Trust and Credibility: Delivering services as per SLA builds long-term customer relationships.
3. Types of SLAs
- Customer-based SLA
- Agreement with a specific customer for a range of services.
- Tailored to the unique needs of that customer.
- Example: An IT company provides network support, server management, and database maintenance for a single client, all under one SLA.
- Service-based SLA
- Covers a single service for multiple customers.
- All customers receive the same service standards.
- Example: An internet service provider guarantees 99.9% network uptime for all its corporate customers.
- Multi-level SLA
- Combines multiple layers of service agreements across different levels:
- Corporate Level: General standards applicable to all services.
- Customer Level: Specific standards for an individual customer.
- Service Level: Detailed standards for a particular service.
- Example: A cloud provider may have an overarching SLA for all customers (corporate level), plus specific uptime guarantees for its premium customers (customer level) and different response times for storage and compute services (service level).
- Combines multiple layers of service agreements across different levels:
4. SLA vs SLO vs SLI
| Term | Definition | Example |
|---|---|---|
| SLA (Service Level Agreement) | A contractual agreement defining the expected service level and consequences of failing to meet it. | 99.9% monthly uptime guarantee, with a refund if this target isn’t met. |
| SLO (Service Level Objective) | A specific, measurable goal within the SLA that the service provider strives to meet. | Resolve 95% of critical issues within 1 hour. |
| SLI (Service Level Indicator) | The metric or measurement used to track and measure service performance against the SLO. | Actual uptime percentage for the last 30 days = 99.95% |
Example Explanation:
- SLA: The formal document stating that the service must have 99.9% uptime.
- SLO: The target for service availability that the provider aims to achieve (e.g., 99.9%).
- SLI: The actual measurement of uptime, which might be 99.95% over a given period.
In nutshell:
- SLAs are binding agreements that set expectations between service providers and customers.
- SLOs are internal goals or targets within the SLA.
- SLIs are the actual performance measurements tracked to determine whether SLOs are met.
1. Scope of Services
The Scope of Services defines what services are included in the SLA, outlining the boundaries and extent of what the service provider will deliver. This is a critical section because it ensures both parties have a shared understanding of the agreement.
What to Include in the Scope:
- Service Description: A detailed overview of the services being provided (e.g., IT support, cloud hosting, customer support).
- Service Hours: Specify whether the service is available 24/7, during business hours, or on specific days.
- Example: “IT support is available from Monday to Friday, 8 AM to 6 PM.”
- Geographical Coverage: If applicable, mention the regions where the service is available.
- Dependencies: Identify external dependencies (e.g., third-party services) that could affect service delivery.
2. Service Performance Metrics
Service Performance Metrics are the specific standards and measurable indicators used to track service quality. These metrics help assess whether the service provider is meeting the agreed service levels.
Common Metrics:
- Availability/Uptime (e.g., 99.9% uptime)
- Response Time (e.g., responding to critical incidents within 15 minutes)
- Resolution Time (e.g., resolving minor issues within 4 hours)
- Error Rate (percentage of failed requests)
- Customer Satisfaction (CSAT)
3. Uptime and Availability
Uptime is the percentage of time a service is operational and available to users. This is one of the most critical metrics in an SLA, especially for IT services, cloud platforms, and telecommunications providers.
How Uptime is Calculated:
∗∗Uptime(**Uptime (%)** = (Total time – Downtime) ÷ Total time × 100
Example:
- 99.9% uptime = Service can be down for approximately 43.8 minutes per month.
- 99.99% uptime = Service can be down for 4.38 minutes per month.
Uptime Tiers:
| Uptime Level | Allowable Downtime Per Month |
|---|---|
| 99.9% | 43.8 minutes |
| 99.99% | 4.38 minutes |
| 99.999% | 26 seconds |
4. Response and Resolution Time
Response Time and Resolution Time are two distinct but equally important metrics in SLAs, especially for customer support or IT services.
Response Time:
The time it takes for the service provider to acknowledge a customer’s request or incident.
- Example: “Critical issues will receive a response within 15 minutes.”
Resolution Time:
The time it takes to resolve the issue and restore normal service.
- Example: “High-priority incidents will be resolved within 4 hours.”
Classification of Incidents:
- Critical (P1): Entire service is down — response in 15 minutes, resolution in 2 hours
- High (P2): Major service impact but partially operational — resolution in 4 hours
- Medium (P3): Minor issues — resolution in 24 hours
- Low (P4): General requests — resolution in 48 hours
5. Responsibilities of Service Provider and Customer
Clearly defining the roles and responsibilities of both parties ensures accountability and smooth service delivery.
Service Provider Responsibilities:
- Deliver services according to the SLA.
- Monitor performance and provide regular reports.
- Notify the customer of any planned maintenance or downtime.
- Respond to and resolve incidents within the agreed timeframe.
Customer Responsibilities:
- Provide accurate and timely information required for service delivery.
- Notify the service provider of incidents or service disruptions.
- Ensure their internal infrastructure (e.g., hardware, network) meets service requirements.
- Pay service fees on time.
6. Monitoring and Reporting
Monitoring and Reporting ensure transparency and help both parties track service performance against the agreed standards.
Key Aspects of Monitoring:
- Use automated tools to monitor uptime, response time, and other performance metrics.
- Track performance in real-time for critical services.
SLA Reporting:
Regular reports should include:
- Service Performance Summary: Uptime, response time, resolution time metrics.
- Incidents and Resolutions: List of incidents, their severity, response, and resolution time.
- Compliance Status: Whether service levels were met or breached.
Frequency of Reporting:
- Monthly or Quarterly, depending on the SLA agreement.
7. Penalties and Remedies for SLA Violations
To ensure accountability, an SLA should specify penalties or remedies if the service provider fails to meet the agreed performance levels.
Examples of Penalties:
- Service Credits: Offering free service for the next billing cycle (common in cloud services).
- Example: “For every 1% of uptime below 99.9%, the customer will receive a 10% credit on the monthly fee.”
- Refunds: Partial refunds of the service fee.
- Escalation or Termination: If repeated violations occur, the customer may terminate the agreement without penalties.
8. Exclusions and Limitations
The Exclusions and Limitations section defines circumstances under which the service provider is not held accountable for failing to meet service levels.
Common Exclusions:
- Scheduled Maintenance: Downtime during scheduled maintenance windows.
- Force Majeure: Events beyond the service provider’s control (e.g., natural disasters, war).
- Third-Party Failures: Downtime caused by third-party services or networks.
- Customer-caused Issues: Service failures resulting from the customer’s actions (e.g., misconfigurations, unauthorized access).
Summary of Key Elements:
- Scope of Services – Defines what services are covered.
- Service Performance Metrics – Specifies the standards for service quality.
- Uptime and Availability – Sets the percentage of time the service must be operational.

Example of Realistic Service Levels:
| Metric | Standard |
|---|---|
| Uptime | 99.9% per month |
| Response Time | Critical incidents: 15 minutes |
| Resolution Time | High-priority issues: 4 hours |
4. Negotiation Strategies for SLAs
SLA negotiation is a collaborative process that ensures both parties are satisfied with the agreement. Here are some strategies for a successful negotiation:
For Service Providers:
- Be Transparent: Share your capabilities and limitations upfront.
- Set Reasonable Expectations: Avoid agreeing to unrealistic service levels just to close the deal.
- Focus on Metrics That Matter: Identify the most important metrics for the customer and negotiate based on those.
For Customers:
- Know Your Needs: Understand your business requirements and prioritize critical services.
- Demand Performance-Based Penalties: Ensure there are consequences for failing to meet agreed standards.
- Negotiate Flexible Terms: Build in provisions for service improvement or review after a certain period.
5. Legal Terms and Compliance
Including legal terms and compliance clauses in your SLA is essential to protect both parties and ensure the agreement complies with relevant laws.
Key Legal Terms to Include:
- Liability and Indemnification: Define the extent of the provider’s liability and indemnification obligations.
- Example: “The service provider’s liability is limited to the monthly service fee.”
- Confidentiality: Ensure both parties protect sensitive information.
- Data Protection and Privacy: Include clauses on data security and compliance with GDPR, Japan’s Act on Protection of Personal Information (APPI), or other relevant regulations.
- Force Majeure: Specify events beyond control (e.g., natural disasters, war) that release the provider from liability.
- Termination and Dispute Resolution: Outline the conditions for termination and how disputes will be handled (e.g., arbitration or legal action).
Here’s a detailed explanation of the key SLA performance metrics:
1. Availability/Uptime Percentage
Availability (Uptime) is the percentage of time a service or system is operational and accessible during a specified period. It is one of the most important metrics in SLAs, especially for IT services, cloud platforms, and telecommunications providers.
Formula to Calculate Uptime:
\text{Uptime (%) =} \left( \frac{\text{Total Time – Downtime}}{\text{Total Time}} \right) \times 100
Example:
For a service that operates 24/7:
- 99.9% uptime means the service can be down for 43.8 minutes per month.
- 99.99% uptime means the service can be down for 4.38 minutes per month.
Uptime Tiers:
| Uptime Level | Maximum Downtime Allowed Per Month |
|---|---|
| 99.9% | 43.8 minutes |
| 99.99% | 4.38 minutes |
| 99.999% | 26 seconds |
Why It Matters:
High availability is critical for business continuity. A failure to meet uptime requirements can lead to financial loss, customer dissatisfaction, and SLA penalties.
2. Incident Response Time
Incident Response Time is the time taken for the service provider to acknowledge an issue after it is reported. It reflects how quickly the provider reacts to service disruptions or requests.
Response Time Targets Based on Incident Severity:
| Incident Severity | Response Time |
|---|---|
| Critical (P1) | 15 minutes |
| High (P2) | 1 hour |
| Medium (P3) | 4 hours |
| Low (P4) | 24 hours |
Why It Matters:
Faster response times reduce downtime, minimize business impact, and improve customer trust.
3. Mean Time to Repair (MTTR)
Mean Time to Repair (MTTR) is the average time required to diagnose, repair, and restore a service to full operation after an incident occurs. It measures how quickly the service provider can resolve issues.
Formula to Calculate MTTR:
MTTR = Total Downtime ÷ Number of Incidents\text{MTTR = Total Downtime ÷ Number of Incidents}
Example:
If a service experiences 5 incidents in a month with a total downtime of 10 hours, the MTTR is:
MTTR = 10 ÷ 5 = 2 hours per incident\text{MTTR = 10 ÷ 5 = 2 hours per incident}
Why It Matters:
MTTR is a key metric for understanding the efficiency of the service provider’s repair processes. Shorter MTTR means faster recovery and less disruption.
4. Mean Time Between Failures (MTBF)
Mean Time Between Failures (MTBF) is the average amount of time a service or system operates without failure. It indicates the reliability of the service.
Formula to Calculate MTBF:
MTBF = Total Uptime ÷ Number of Failures\text{MTBF = Total Uptime ÷ Number of Failures}
Example:
If a system runs for 1,000 hours and experiences 4 failures, the MTBF is:
MTBF = 1,000 ÷ 4 = 250 hours between failures\text{MTBF = 1,000 ÷ 4 = 250 hours between failures}
Why It Matters:
A higher MTBF indicates greater reliability and fewer service disruptions. It’s essential for measuring long-term performance.
5. First Call Resolution (FCR)
First Call Resolution (FCR) is the percentage of incidents or support requests that are resolved on the first contact without the need for escalation or follow-up.
Formula to Calculate FCR:
\text{FCR (%) = (Number of Issues Resolved on First Contact ÷ Total Issues) × 100}
Example:
If 80 out of 100 incidents are resolved on the first call, the FCR is:
\text{FCR = (80 ÷ 100) × 100 = 80%}
Why It Matters:
High FCR indicates better service efficiency and customer satisfaction. Customers prefer quick resolutions without the need for multiple contacts.
6. Customer Satisfaction (CSAT)
Customer Satisfaction (CSAT) measures how satisfied customers are with the service provided. It’s usually gathered through post-service surveys.
Formula to Calculate CSAT:
\text{CSAT (%) = (Positive Responses ÷ Total Responses) × 100}
Example:
If 90 out of 100 customers give a positive rating, the CSAT score is:
\text{CSAT = (90 ÷ 100) × 100 = 90%}
Why It Matters:
CSAT is a critical metric for understanding the customer experience and identifying areas for improvement. A high CSAT score reflects excellent service quality.
Summary of Key Metrics:
- Availability/Uptime Percentage: Measures service availability and operational time.
- Incident Response Time: Tracks how quickly service providers respond to incidents.
- Mean Time to Repair (MTTR): Measures the average time to fix and restore services.
- Mean Time Between Failures (MTBF): Indicates the reliability of the service.
- First Call Resolution (FCR): Assesses the percentage of issues resolved on the first contact.
- Customer Satisfaction (CSAT): Reflects how satisfied customers are with the service.

| Jitter | Variability in packet delay | <30 ms |
Example:
A telecommunications provider may guarantee 99.99% network uptime, meaning downtime should not exceed 4.38 minutes per month. If downtime exceeds this, the customer is entitled to compensation.
4. Customer Support SLAs (Response Time, Customer Satisfaction)
Customer support SLAs focus on response time, resolution time, and customer satisfaction, ensuring that service requests and incidents are handled promptly. These SLAs are critical for businesses with high customer interaction, such as e-commerce, telecom, and SaaS companies.
Key Metrics in Customer Support SLAs:
| Metric | Description | Target Example |
|---|---|---|
| First Response Time | Time taken to respond to a customer inquiry | 10 minutes for priority tickets |
| Resolution Time | Time taken to fully resolve a request | 4 hours for high-priority cases |
| First Call Resolution (FCR) | Percentage of issues resolved on the first contact | 80% |
| Customer Satisfaction (CSAT) | Customer rating on the quality of service | 90% satisfaction rate |
Why Customer Support SLAs Matter:
- Ensure faster responses and better service quality.
- Improve customer loyalty and reduce churn.
- Help organizations measure and optimize support performance.
Example:
A customer support SLA for an e-commerce company may guarantee that 90% of inquiries are resolved within 24 hours, with first responses within 10 minutes for high-priority requests.

| SLA Type | Key Metrics | Examples |
|---|---|---|
| ITIL-based SLAs | Incident response time, resolution time, uptime, CSAT | IT support for internal services |
