Special Considerations Leading to Variations in a BOM
Many variations can exist for a BOM. The following sections outline some typical examples.
Supplier
It might be necessary to source a material from more than one supplier.
Reasons
What Is Affected
Availability of color
Country of origin (COO) in relation to where the product is built
Fabric information (content, weight, construction, colors, width, price)
Quantity (affected by width)
Cost (affected by price and yield)
Lead time
Quota capacity (affected by COO)
Source
It might be necessary to have a product built in more than one factory or from more than one source.
Reasons
What Is Affected
High quantities
Testing new factories
Stiffeners or interlining choices
Fabric information (content, weight, construction, colors, width, price)
Quantity (affected by width)
Cost (affected by price and yield)
Lead time
Quota capacity (affected by COO)
Sizing
A product can be offered in multiple size classes, and sizes within a size class. The materials and trim used in a product can be affected by either or both of these factors.
Component
What Is Affected
Graded zippers
Lengths (varies)
Buttons
Number use
Shoulder Pads and Heads
Different size categories (varies)
Elastic
Size class (larger sizes only)
Pocket Linings
Size class (set size for a group of sizings)
Belt Loops
Number (may vary by size)
Bra Hooks
Number (may vary by size)
Pant Drops
Relationship between jacket and pant sizes
Placement of Trims
Shoulder pads, logos, loops, and so on
Colorways Offered
Different colors featured in various sizes or size categories
Colorway
A product can be produced in many different colors. The materials, trim, and especially material colors are affected by this variety. Some components that might be affected include:
• Shell colors
• Contrast colors
• Interlining color used
• Shoulder pad or other trim item colors
• Whether or not a product is lined (for example, only white items may be lined)
• Fabric from different sources (content, weight, construction, colors, width, price)
• Quantity (affected by width)
• Cost (affected by price and yield)
• Lead time
• Quota capacity (affected by COO)
Other Variations That Affect BOM Usage
• Accommodating multiple pieces (jacket, skirt, pant)
• Product lined or unlined (different versions)
• Complex materials
• Colorway graphics (color blocking)
• Colorways used to represent different fabrics such as denim or twill, and leather or fabric (affects fabric information, yield, width, care, and so on)
• Country the product is marketed in
Variations that May Affect Layout
• Different sections of BOM have different columns
• Different BOM views (required for various user groups)
• FOB or CMT production methods
• Type of product (footwear or apparel)
• Vendor access
