SLA Breaches

1. Definition

• SLA (Service Level Agreement): A formal contract or agreement between a service provider and a client that specifies expected performance levels (e.g., uptime, response time, delivery time, resolution time).
• SLA Breach: When the provider fails to meet the agreed service level.

Example: SLA guarantees 95% of deliveries within 2 days. If only 92% are on time → SLA breach.

2. Formula

$\text{SLA Breach Rate (\%)} = \frac{\text{Number of breached SLAs}}{\text{Total SLA commitments}} \times 100$

---

3. Common SLA Metrics That Can Be Breached

• IT/Cloud Services:
  • Uptime < 99.9%
  • Response time > agreed threshold
• Customer Support:
  • Ticket not responded within 4 hours
  • Resolution not within 24 hours
• Logistics / Supply Chain:
  • Late deliveries
  • Order accuracy below target
• Manufacturing:
  • Defect rate higher than agreed

4. Consequences of SLA Breaches

• Financial penalties: Refunds, service credits.
• Customer dissatisfaction: Loss of trust.
• Reputational damage: Negative reviews, churn.
• Operational strain: More escalations and firefighting.

---

5. Example

• SLA: “95% of orders delivered within 48 hours.”
• Total orders: 1,000
• Delivered within SLA: 920
• Breached SLAs = 1,000 – 920 = 80

$\text{SLA Breach Rate} = \frac{80}{1000} \times 100 = 8\%$

Summary

• SLA breach = service below promised standard.
• Tracked with SLA Breach Rate %.
• High breach rate → penalties, churn, inefficiency.
