Standards for Technological Literacy Standard 8: Attributes of Design The engineering design process includes Defining a problem, Brainstorming, Researching and generating ideas, Identifying criteria and specifying constraints, Exploring possibilities, Selecting an approach, Developing a design proposal, Making a model or prototype, Testing and evaluating the design using specifications, Refining the design, Creating or making it, and Communicating processes and results NOTE: The process is iterative and different steps are revisited as necessary in order to

arrive at a solution. NASA Model of Engineering Design Process Tufts University Example of Engineering Design Process
