Final answer:
In the technological design process, 'establish criteria and prepare the initial design' is part of developing a detailed design, 'redesign and retest as necessary' is part of refining the design, 'define a need and research related information' corresponds to identifying a problem or need, and 'build and test a prototype' refers to testing and evaluation of the prototype.
Step-by-step explanation:
The process of technological design often follows specific stages to achieve a functional product. The actions described in your question correspond to different stages in this design process. Let me walk you through each one.
- a. Establish criteria and prepare the initial design: This step happens early in the design process, where requirements are defined and the preliminary design is created, commonly referred to as Develop a detailed design.
- b. Redesign and retest as necessary: This action corresponds to Refining the design. If initial testing indicates issues, the design is tweaked and tested again, often multiple times to ensure it meets the necessary criteria.
- c. Define a need and research related information: This is the first stage, where you Identify a problem or a need and gather all related information to understand the design requirements and constraints.
- d. Build and test a prototype: After a concept is selected and a detailed design is developed, a prototype is built. This stage is known as Testing and evaluation of the prototype, and it is here that the design proves its worth by meeting the set criteria and constraints.
Each step is crucial in moving from an idea to a tangible, functioning product, employing cycles of iteration to refine the design to meet the specified need.
