which would most likely be done while designing a solution?\no researching the current uses of a fuel type\no sketching a diagram of a new medical device\no reporting the results of using a prototype\no redesigning a model airplane that did not fly well
Answer
Brief Explanations:
When designing a solution, sketching a diagram of a new medical device is a common activity to visualize and plan the design. Researching current uses of a fuel type is more about gathering information before design. Reporting results of using a prototype is after the design - prototype - testing phase. Redesigning a model airplane that didn't fly well is a post - design improvement step.
Answer:
sketching a diagram of a new medical device
