Final answer:
The main purpose of a brainstorming session is to generate many ideas. The concept is widely used in various fields to encourage expansive thinking without immediate judgment or selection, thus allowing for a diverse range of potential solutions to emerge.
Step-by-step explanation:
The main purpose of a brainstorming session is to generate many ideas. Brainstorming is used to encourage the free flow of thoughts and ideas, which can come from a variety of sources such as existing products, current scientific principles, or creative thought processes. Whether it's in engineering, business strategies, or classroom assignments, the goal is not immediately to evaluate or select the best idea, but rather to generate a wide range of possibilities. Brainstorming is a critical step in the creative process where all kinds of ideas are welcomed and captured, with the intent of combining and refining them later to arrive at the most effective solution.
During a brainstorming session, ideas that initially seem infeasible should not be immediately discarded, as they could lead to more viable solutions upon further exploration. The elimination and implementation stages come after the brainstorming process, where the best ideas are selected and executed. This is the essence of a typical design process as well, where a design team would use brainstorming sessions to explore all possible solutions before narrowing them down.
