Final answer:
An idea develops during the insight step of Young's creative process model, which follows preparation and incubation, and precedes the verification step where the idea is refined into a final solution.
Step-by-step explanation:
An idea develops during the insight step of Young's creative process model. The stages of Young's model include Preparation, where a problem is investigated in all directions; Incubation, a period of subconscious processing; Insight, also known as the 'aha!' moment when a creative idea emerges; and finally, Verification, where the idea is tested and developed into its final form.
Different creative and scientific disciplines may use similar but distinct models for problem-solving and design. In scientific methods, steps may include making observations, formulating hypotheses, and conducting experiments. In engineering and design, they may include defining problems, generating ideas, prototyping, and testing.
Searching internally for ideas during these processes is often referred to as 'brainstorming' or 'mind searches,' and involves methods like design sessions and idea dumps. These help in generating multiple solutions before moving on to the more structured approaches of prototyping and iteration.
