Review Interface Descriptions for Completeness

The interfaces should include, in addition to product-component interfaces, all the interfaces with the product integration environment.

• Review interface data for completeness and ensure complete coverage of all interfaces. Consider all the product components and prepare a relationship table. Interfaces are usually classified in three main classes: environmental, physical, and functional. Typical categories for these classes include the following: mechanical, fluid, sound, electrical, climatic, electromagnetic, thermal, message, and the human-machine or human interface.
• Ensure that product components and interfaces are marked to ensure easy and correct connection to the joining product component.
• Periodically review the adequacy of interface descriptions. Once established, the interface descriptions must be periodically reviewed to ensure there is no deviation between the existing descriptions and the products being developed, processed, produced, or bought.
