• We can look at the design process as mapping Functional Requirements (FRs) to Design Parameters (DPs). We can also look at mapping from the design parameters to the Process Parameters (PPs) as the task of process engineering.
- try to talk in general terms that focus on the function instead of solution (e.g., “the automobile should be able to move on ground with a 12 inch variation in height” instead of “the axle clearance should be 12 inches”).
• As an example consider the progress in the computer industry. Specifically Moore’s Law - about every 2 years the number of transistors on a chip will double (implies memory doubling, speed doubling, etc) this has proven to be remarkably accurate.
• We can combine a number of new and old features in products as FRs. These will affect both customer expectations and product cost. A graph shows what marketing departments research in terms of customer needs.
