📘 Topic: Service Delivery Processes: IT Service Continuity Management (ITSCM)

Subject: Information Technology Infrastructure

---

1. 📌 Introduction

Modern organizations depend heavily on IT services (servers, networks, cloud systems). Any disruption like power failure, cyberattack, hardware crash, or disaster can stop business operations.

👉 To prevent such losses, organizations use IT Service Continuity Management (ITSCM).

---

2. ✅ Definition

IT Service Continuity Management (ITSCM) is the process of ensuring that IT services can continue or be quickly restored after a major disruption or disaster, so that business operations are not severely affected.

👉 Simple idea: It ensures IT services keep running even during disasters.

---

3. 🎯 Objectives of ITSCM

• Ensure minimum downtime of IT services
• Protect critical business operations
• Reduce impact of disasters
• Enable fast recovery of systems
• Maintain business continuity

---

4. ⚙️ Scope of ITSCM

ITSCM covers:

• Servers and data centers
• Networks and communication systems
• Applications and databases
• Cloud infrastructure
• Critical IT services

---

5. 🔄 IT Service Continuity Process

🔹 1. Business Impact Analysis (BIA)

• Identify critical IT services
• Determine impact of failure

📊 Example:

• Banking system downtime → high financial loss

---

🔹 2. Risk Assessment

• Identify threats like:

  • Natural disasters
  • Cyberattacks
  • Hardware failure

---

🔹 3. Continuity Strategy Development

• Decide how services will be protected

📊 Options:

• Backup systems
• Cloud replication
• Disaster recovery sites

---

🔹 4. Implementation of Continuity Plans

• Set up backup systems
• Configure disaster recovery centers

---

🔹 5. Testing and Training

• Regular testing of recovery plans
• Train IT staff

---

🔹 6. Recovery and Restoration

• Restore services after disruption
• Ensure normal operations resume quickly

---

🔹 7. Review and Improvement

• Improve plan based on past incidents

---

6. 🧠 Real-Life Example

A bank uses ITSCM:

• Primary server fails due to power outage
• Backup server in another location takes over
• Customers continue transactions without interruption

👉 Result:

• No major service downtime
• Business continuity maintained
