Part 44:
Integrated generic resource: Product structure configuration

1 Scope

• the relationships among the components and assemblies of products;
• the relationships among products and their components as made by modification of other products;

  EXAMPLE 1   The machining of a product from another product is an example of a modification.

• the description of a product as defined by customer needs;
• the dependencies among specifications of a product in order to represent possible product variations to present to a customer;
• the management of the structure for configuration of assemblies and components as planned for manufacture;
• the decomposition of a product to support different product life cycle activities;

  EXAMPLE 2   An organization maintains one bill-of-material structure for a product that enumerates the quantity of each component used in each assembly, and a second bill-of-material that decomposes a product with multiple assemblies into the individual components. See annex Examples for more examples of different product structure reports that are supported.

• multiple versions of a single product that are equivalent with respect to form, fit, and function.

The following are outside the scope of this document:

• the relationships among different product definitions for the same product;

  NOTE 1   The relationships among different product definitions for the same product are supported by the product_definition_schema of ISO 10303-41.

  EXAMPLE 3   The relationship of a product definition for a component in a preliminary design to a corresponding product definition for the same component in a detailed design is an example of this type of relationship.

• administrative activities of the product life cycle including approvals, security classifications, contractual arrangements, and supplier organizations;
• the change process for a product, including the reason for change and what aspect of a product has changed;
• the decisions made, and their reasons, during the product life cycle;
• the physical connections among components of a product;
• the properties that a product constituent may have;

  NOTE 2   A mechanism is defined in the product_property_definition_schema in ISO 10303-41 to support the association of properties with components. The actual associations are included in various application protocols that are parts of this International Standard. For example, the details of what a material property is and how it is defined are out of scope, as well as the fact that a component has a material property.

• multiple versions of a single product that are not form, fit, and function equivalent.

  NOTE 3   The concept of versions of a product is defined in the product_definition_schema in ISO 10303-41.
