Final answer:
When creating an OSI BOM for non-standard components, it is important to have a detailed understanding of the components, their acquisition or fabrication status, and the necessary schematic diagrams and embedded code.
Step-by-step explanation:
When creating an OSI BOM for non-standard components, all the components must first have a detailed understanding of their shapes and dimensions, whether they will be acquired from external vendors or fabricated within the company, and if fabricated within the company, the materials and fabrication processes to be used. Additionally, a detailed schematic diagram of any electrical subsystems and computer code for any embedded Assembly processes should be included.
