ServiceNow ITSM Core Modules – Incident, Problem, Change, and Request Management


Master ServiceNow ITSM core modules required for jobs. Learn Incident, Problem, Change, and Request Management with real-world workflows, SLAs, approvals, and hands-on configuration.

Incident Management

Overview

Incident Management is used to restore normal service operations as quickly as possible and minimize business impact.

Incident Lifecycle

Typical incident flow:

  1. New
  2. In Progress
  3. On Hold
  4. Resolved
  5. Closed

Each state represents a stage in incident handling.

Assignment Groups

Assignment groups define which team is responsible for resolving the incident.

Examples:

  1. Service Desk
  2. Network Team
  3. Linux Support
  4. Application Support

Assignment can be manual or automatic using rules.

Priorities and SLAs

Priority is calculated based on:

  1. Impact
  2. Urgency

SLA (Service Level Agreement) defines:

  1. Response time
  2. Resolution time

Example:

High priority incidents must be resolved within 4 hours.

Incident States

Common states:

  1. New
  2. In Progress
  3. On Hold
  4. Resolved
  5. Closed

State transitions control workflow behavior.

Major Incident Process

Major Incidents are high-impact incidents affecting critical business services.

Key features:

  1. Dedicated major incident manager
  2. Faster approvals
  3. War-room communication
  4. Post-incident review

Hands-On: Create Incidents

  1. Navigate to Incident → Create New
  2. Fill in caller, category, impact, urgency
  3. Save and observe auto-generated incident number

Hands-On: Configure Auto-Assignment

  1. Navigate to System Policy → Assignment Rules
  2. Create a new assignment rule
  3. Define conditions (for example: Category = Network)
  4. Assign to the correct group
  5. Test by creating a new incident

Hands-On: Test SLA Breach Scenarios

  1. Navigate to Service Level Management → SLAs
  2. Review incident SLAs
  3. Create a high-priority incident
  4. Delay resolution intentionally
  5. Observe SLA countdown and breach behavior

Problem Management

Incident vs Problem

  1. Incident: A single service interruption
  2. Problem: The underlying root cause of one or more incidents

Example:

Multiple email incidents caused by a mail server failure indicate a problem.

Root Cause Analysis (RCA)

RCA is used to identify the real cause of issues.

Common methods:

  1. 5 Whys
  2. Fishbone diagram
  3. Fault tree analysis

Known Error Database (KEDB)

A Known Error is a documented problem with a confirmed root cause and workaround.

Benefits:

  1. Faster incident resolution
  2. Knowledge reuse

Hands-On: Create Problems from Incidents

  1. Open an existing incident
  2. Use the Create Problem option
  3. Link related incidents
  4. Save the problem record

Hands-On: Link Root Cause and Known Errors

  1. Update problem record with root cause details
  2. Mark the problem as Known Error
  3. Link workaround documentation
  4. Verify KEDB entry

SECTION 3: Change Management

Types of Changes

  1. Normal Change: Requires approval and risk assessment
  2. Standard Change: Pre-approved, low-risk
  3. Emergency Change: Urgent fixes requiring fast approval

Change Lifecycle

Typical change flow:

  1. New
  2. Assess
  3. Authorize
  4. Implement
  5. Review
  6. Closed

Approval Workflows

Approvals can include:

  1. Manager approval
  2. CAB approval
  3. Risk-based approval

Approval logic is controlled using workflows or Flow Designer.

CAB Process

Change Advisory Board reviews and approves changes based on:

  1. Risk
  2. Impact
  3. Business priority

Risk Calculation

Risk is calculated using:

  1. Impact
  2. Urgency
  3. Change type

Higher risk changes require additional approvals.

Hands-On: Create Change Records

  1. Navigate to Change → Create New
  2. Select change type
  3. Fill required fields
  4. Save and submit for approval

Hands-On: Configure Approvals

  1. Navigate to Flow Designer or Workflow Editor
  2. Open change approval flow
  3. Add approval conditions
  4. Test approval behavior

SECTION 4: Request Management (Service Catalog)

Service Catalog Overview

The Service Catalog provides a user-friendly way to request services.

Examples:

  1. Laptop request
  2. Software installation
  3. Access requests

Catalog Items

Catalog items define what users can request.

Each item includes:

  1. Variables
  2. Pricing (optional)
  3. Approval logic
  4. Fulfillment tasks

Record Producers

Record Producers create records directly in tables using catalog forms.

Example:

Creating an incident from a catalog item.

Request, RITM, and Task

ServiceNow creates multiple records:

  1. Request (REQ): Parent request
  2. Requested Item (RITM): Individual items
  3. Catalog Task (TASK): Fulfillment work

Approval Workflows

Approvals can be:

  1. User manager
  2. Group-based
  3. Multi-level approvals

Hands-On: Create a Catalog Item

  1. Navigate to Service Catalog → Catalog Definitions → Maintain Items
  2. Create a new catalog item
  3. Add variables
  4. Assign category
  5. Save and publish

Hands-On: Build an Approval Process

  1. Open the catalog item
  2. Define approval conditions
  3. Add approval flow using Flow Designer
  4. Submit a request and test approval
