Ideation tool for what?

While there may be an element of artistic self-expression in the designer's use of ideation tools, the strength of the tool chosen (words, sketches, models, or computing, or combinations thereof) in practice-based or practice-led creative environments, lies in the way it helps the designer formulate the problem in hand in what then becomes a solution-driven process. Throughout this process of identifying the problem, of generating, developing and communicating the idea, the choice of ideation tool(s) can be crucial in persuading interested parties to help realise the idea.
