The **Design & Planning domain** is one of seven domains in the [[Common Service Data Model|Common Service Data Model]] (CSDM), a reference architecture developed by [[ServiceNow|ServiceNow]] that provides prescriptive guidance on service-related definitions and data modeling within the ServiceNow AI Platform. This domain represents tables used by [[Enterprise Architecture (ServiceNow)|Enterprise Architecture]] (EA), formerly known as Application Portfolio Management (APM), for designing and planning enterprise applications before deployment. Records in this domain are not direct targets of [[Information technology service management|ITSM]] processes such as [[Incident management (ITSM)|Incident]], [[Problem management|Problem]], and [[Change management (ITSM)|Change]] management, as they represent the logical design of applications rather than operational instances. The Design & Planning domain contains three primary [[Configuration item|configuration item]] classes: [[Business Capability (CSDM)|Business Capability]], [[Business Application (CSDM)|Business Application]], and [[Information Object (CSDM)|Information Object]]. Business Capabilities describe what an organization does at a high level to execute its business model, typically represented in a hierarchical structure with no more than six levels. Business Applications represent all software and infrastructure configured to provide business functionality, serving as the logical representation of application instances used across environments and geographies. Information Objects describe the types of data used within business applications, such as [[Personally identifiable information|PII]] or [[Payment Card Industry Data Security Standard|PCI]], supporting governance and compliance scoping. These tables are supported by foundational entities including [[Product Model (CSDM)|Product Model]], [[Value Stream (CSDM)|Value Stream]], [[Business Process (CSDM)|Business Process]], and [[Common Data (CSDM)|Common Data]]. Common personas in this domain include Enterprise Architects and Application Owners.
