Fixing a price
• Estimate value to end users (subtract any switching costs)
• Also look at equivalent products for pricing

Product cost
Price ≠ Cost !

• Cost estimation is an art• Several layers of detail, use what’s appropriate• Manufacturing process matters....a lot!• Volume matters.....a lot!• Design details matter…a lot• Everything starts with a good BOM• Cost of prototype ≠ cost of product!
• See Ulrich and Eppinger DfM Chapter for details

Product costs
• More than parts plus labor• Must account for all costs required to
produce product• Product cost models differ for
different companies

Prototype BOM
As a team, create a BOM table for the prototype you will have at the Design Show. Part, source, cost. Include fabricated and purchased components. Make guesstimates where appropriate.Create in Excel, upload to Google site.
