Bill of Materials Top Level Example
The drawing above shows an example trolley for moving heavy items. Though our example may not be the best designed trolley around, it is simplified to show off the different assemblies and raw materials. The example also shows how the bill of materials can easily be modified due to a change in the design.  In this bill of materials example we will start at the top level, and indentify the individual components. To simplify things in this example, the bill of materials has some basic information omitted e.g. cost for clarity.
At the top level there are only two different parts: Example 1
For this example, there's not much too show with only two assemblies, as essentially its only the top level of the multi level example. With larger assemblies this much more involved. If you see from the example above, it is easy to change the top bill of materials should the quantity change from a three wheeled to a four wheeled design, by simply adjusting the quantities associated with the plywood platform and the wheel housing (part 110-001) from a quantity of 3 to 4 |
