Service Catalog

The Service Catalog manages your IT organization's service portfolio across three tiers.

Architecture (3-Tier)

Service Descriptions
        ↓
Horizontal Catalog (All Services)
        ↓
Vertical Catalog (Customer-specific) [Enterprise]

Service Descriptions

Standardized descriptions of individual IT services:

Field	Description
code	Unique identifier (e.g. "SVC-001")
title	Service title
description	Detailed description
scope_included	What is included
scope_excluded	What is explicitly excluded
compliance_tags	Compliance references (ISO-27001, GDPR etc.)
version	Version number
status	active, inactive, deprecated

Horizontal Catalog

Groups service descriptions into thematic collections. Each tenant has a default horizontal catalog.

Example: "IT Infrastructure Services" contains:

• Server provisioning
• Network management
• Backup & recovery

Vertical Catalog (Enterprise)

Customer-specific view of the horizontal catalog:

• Based on a horizontal catalog
• Configurable per customer or industry segment
• Individual services can be overridden (different scope, different SLA)
• Override types: scope_change, pricing_override, custom_description

Asset-Service Linking

Services can be linked to assets:

Asset "web-server-01"
  → Service "Web Hosting (Standard)"
  → Service "SSL Certificate Management"

This linking forms the basis for service impact analysis.
