A Bill of Materials (BOM) is a comprehensive list that outlines all the components, parts, and materials needed to manufacture a product. It serves as a blueprint for production, detailing each item's specifications, quantities, and relationships to one another. This document is essential for ensuring that manufacturers have everything required to assemble a product efficiently. BOMs are commonly used in various industries, including manufacturing, electronics, and construction. They help streamline the production process, manage inventory, and facilitate communication between different departments. By providing clear information, BOMs contribute to reducing errors and improving overall efficiency in product development.
