The "Napkin Techniques" refer to a set of simple, visual methods used for brainstorming and problem-solving, often employed in business and creative settings. These techniques involve sketching ideas or concepts on a napkin or any small piece of paper, allowing for quick and informal expression of thoughts. This approach encourages spontaneity and can lead to innovative solutions without the constraints of formal presentations. These techniques can include drawing diagrams, flowcharts, or even simple doodles to represent ideas. The goal is to facilitate communication and collaboration among team members, making complex concepts easier to understand and discuss. By using everyday materials like napkins, participants can feel more relaxed and open to sharing their ideas.
