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.
