A **Hardware Model** is a [[Product Model (CSDM)|Product Model (CSDM)]] type within the [[Foundation (CSDM domain)|Foundation domain]] of 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. A Hardware Model represents physical hardware products such as servers, workstations, network equipment, storage devices, and other tangible technology assets that an organization deploys, manages, or consumes. Hardware Models are recorded in the cmdb_hardware_product_model table and are one of ten base product model types extended from the cmdb_model table, alongside [[Application Model (CSDM)]], [[System Component Model (CSDM)|System Component Model (CSDM)]], [[Service Model (CSDM)|Service Model]], [[Software Model (CSDM)|Software Model (CSDM)]], [[Content Product Model (CSDM)|Content Product Model (CSDM)]], [[Contract Model (CSDM)|Contract Model (CSDM)]], [[Facility Model (CSDM)]], [[Consumable Model (CSDM)|Consumable Model (CSDM)]], and [[Enterprise Good Model (CSDM)|Enterprise Good Model (CSDM)]]. Hardware Models can be populated automatically through [[ServiceNow Discovery|ServiceNow Discovery]] once operational, enabling organizations to track manufacturer, model specifications, compatibility, and end-of-life details. Hardware [[Configuration item|CIs]] and [[Asset|assets]] reference Hardware Models using the "Model ID" attribute, following the [[Tangible Life Cycle Process (CSDM)|Tangible Life Cycle Process (CSDM)]] with stages including Ideation, Purchase, Inventory, Deploy, Operational, Defective, Missing, End of Operation, and End of Life. This enables [[Product Owner (CSDM)|Product Owners]] to manage hardware product portfolios and track life cycle status across the [[CSDM Service Life Cycle|CSDM Service Life Cycle]].
