ISO 10303-239:2005 specifies the application protocol for Product life cycle support.

The following are within the scope of ISO 10303-239:2005:

• information for defining a complex product and its support solution;
• information required to maintain a complex product;
• information required for through life configuration change management of a product and its support solution;
• the representation of product assemblies including:
  • the identification and representation of parts, their versions, definitions, and documentation and management information, such as dates and approvals assigned to parts;
  • the representation of multiple product structure views and product breakdowns;
  • the representation of the shape of an assembly as the composition of the shape representation of its components;
  • the identification of positions within an assembly of parts to which component parts may be attached;
  • the association of valued properties to a part or to an assembly;
  • the representation of interfaces between products;
  • the classification of parts, documents and assemblies.
• the representation of a product through life including:
  • the representation of product requirements and their fulfilment;
  • the representation of existing or potential future products;
  • the identification of the configuration of a product for a given role;
  • the specification of effectivity constraints applied to configuration of a product;
  • the representation of predicted and observed states of products.
• the specification and planning of activities for a product including:
  • the specification of tasks to be performed on a product;
  • the representation of conditions for performing the tasks, including the resources required and the location of the resources and product;
  • the representation of the type of person and skills required for performing a task;
  • the representation of planning and scheduling of the tasks and the management and authorization of the subsequent work.
• the representation of the activity history of a product including:
  • the recording of the usage of a product and the resource usage;
  • the recording of the activities performed on a product and the resource usage.
• the representation of the product history including:
  • a historical record of the states of a product;
  • a historical record of the configuration status of the product;
  • the location of product data;
  • the observation of product data.
