Fill in the blank with the correct definition: A design process is a ______________________________
A design process is a systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve or satisfy human needs or wants and to narrow down the possible solutions to one final choice.
A design process is a random approach, without criteria or constraints, used to develop a single solution for any problem.
A design process is a creative guessing game, with no need for criteria or constraints, used to solve only technical problems.
A design process is a step-by-step method, ignoring criteria and constraints, used to develop solutions for natural phenomena.
An example of how you might use a design process in your daily life is:
Planning and organizing a birthday party step by step.
