Match the word to its definition

• the application of scientific knowledge for practical purposes

• criteria

• a first or preliminary version of a design from which other forms are developed.

• technology

• guidelines that define the success of the design

• prototype

• Limitations to a design. Helps keep designs practical and relate directly to the given situation

• constraint

• The process of repeating tasks within a design project

• iteration

An engineer has just finished building a prototype of a lawn tractor that is powered by the sun. Which of the following should be the next step in the design process? 

• Test the prototype to evaluate its performance.

• Ask for funding to build more copies of the prototype.

• Build a second prototype that is different from the first.

• Make changes to the prototype that will increase its performance.

Which of the following statements best describes the term “constraints”?  

• Constraints are the required materials, design, and the amount of time needed to develop a product. 

• Constraints are restrictions of items which can’t be used, limitations on time, and limitations of design. 

• Constraints are examples of prototypes. 

• The research which is done to determine information that should be used in the development of new products.
