Creative problem solving uses tools and methods like brainstorming, thinking outside the box, and the five Ws to find novel solutions. Brainstorming involves generating ideas without criticism, building on others' ideas, and using lead questions to stimulate creativity. Thinking outside the box means approaching problems from new perspectives, like solving the nine dots puzzle by drawing lines outside the implied boundary. The five Ws framework gets a complete story by answering who, what, when, where, and why questions.
