Engineering Organization

Examples of Design and Development Outputs

CAD models, Engineering Reports, Drawings, BOMs

Examples of Controlled Documents

Memos/Reports
Company Procedures
CAD Models
Drawings / BOMs

Minimal Requirements for "Control"

1) Document Number (with Unique ID)
2) Title - Description
3) Version Number
4) Change Management

Configuration Break

A period of time if the product does NOT represent the model/drawing

What are the two ways to document a change on a Controlled Document

1) Roll the Revision
2) Create a new document

When do you "Roll the Revision"?

For a minor change

When do you "get a new part number"?

For a major change

The 3 F's of Changes

1) Form
2) Fit
3) Function

If all 3 are unchanged, roll the rev

Benefit of New Part Number

You preserve the old design

Disadvantage of New Part Number

Cost is higher than rev changes (new parts, new BOMs)

Identification

A collection of qualities that establish uniqueness for each part

Definition

A collection of details that describes each part

Product Structure (Order)

1) End Item (Product)
2) Assembly
3) Part
4) Hardware/COTS
5) Material

End Item

Finished Product

Assembly

Collections of Parts
Have BOMs

May have children

Part(s)

-The simplest designed thing with a drawing
-Includes Materials (only material children)

Hardware/COTs

A component that was NOT designed, but purchased elsewhere

Material

Material, part number, description, revision #

What 2 characteristics should part numbers have?

Unique and Consistent

T/F A Bill of Materials (BOM) for a given drawing is a single-level section of the overall product structure pertaining to what is contained in the drawing.
