1 Chapter 5: Product Specifications Product Design and Development Fourth Edition by Karl T. Ulrich and Steven D. Eppinger

2 Benchmarking Product Design by Otto and Wood, 2001 Form a List of Design Issues Form a List of Related or Competitive Products Conduct an Information Search Establish Best-in -Class Competitors Develop Specifications – Less than – Greater than – Range – Discrete values – Exactly X

3 Sources of Product Information Library Thomas Register Market Share Reporter National Bureau of Standards Census of Manufactures Moody’s Industry Review Consumer Reports Magazine Trade Magazines Patents Market Research Databases – DIALOG, Predicasts, American Demigraphics Web Vendors Technical Specialists Experts/Friends in Industry NAICS (North American Industry Classification System) Codes

4 Benchmarking the Krups 203 Coffee Mill Design Issues – price – noise level – size – grind time – fineness of grind Competitors – Braun – Molinex – Salton – Bosch – Proctor-Silex – Cuisinart

5 Format for submission Need Statement: The coffee grinder has sufficient capacity. Metric and units: Bean capacity in oz. List of 3 competitors: Best: Capresso Infinity Burr Grinder, 8-1/2 ounces Middle: Cuisinart DBM-8 Supreme Grind, 8 ounces Worst: Krups F203, 3 ounces US Patent: Title: Coffee grinder United States Patent Abstract: A coffee grinder has a control circuit for its electric grinder motor which includes a three- position control switch having a resident "Off" position, a resident "On" position, and a non-resident or momentary "On plus Start" position. In the "Off" position power is interrupted to all circuits of the grinder. The "On" position is a resting position which is resumed after the start of each grind cycle in readiness for the start of another grind cycle. The "On plus Start" position is momentary and in which a relay is energized so as to complete a circuit that energizes the grinder motor. In one type of coffee grinder the electrical control circuit includes a timer which can be set to determine the length of the grinding cycle. In another type of coffee grinder the length of the grinding cycle is determined by the presence of a ground coffee receiving bag or other container. In both types of grinders the normal grinding cycle can be terminated by placing control switch in its "Off" position.

6 Standard: NSF/ANSI NSF/ANSI Commercial powered food preparation equipment EN EN Safety of Household and Similar Electrical Appliances Part 2: Particular Requirements for Coffee Mills and Coffee Grinders CENELEC HD 260 Particular Specification for Coffee Grinders and Mills CENELEC HD 260 S3 Safety of Household and Similar Electrical Appliances Part 2: Particular Requirements for Coffee Mills and Coffee Grinders CENELEC UL 763 (Ed. 3) Standard for Motor-Operated Commercial Food Preparing Machines HD 260 HD 260 S3 UL 763 (Ed. 3) Group Members Name and CM: David Stienstra and Patsy Brackin, CM 165

7 Quiz for Today 20 Minutes From your customer needs statements, select one statement and develop an appropriate metric. Perform benchmarking to find the current range for this metric among your competitors’ products. Do a search of the US Patent web-page and find one patent that is relevant for your product. (www.uspto.gov)www.uspto.gov Locate the title of at least one standard that is relevant for your product. (http://www.nssn.org/)http://www.nssn.org/ (Make sure find title, abstract, or keyword is selected.) Include a CM for one team member.
