The "Nine Windows" is a creative problem-solving technique that helps individuals and teams explore different perspectives on a challenge. It involves visualizing a grid with three rows and three columns, where each cell represents a different viewpoint: past, present, and future, along with different levels of analysis, such as individual, group, and system. By filling in each cell with ideas or solutions, participants can generate a wide range of possibilities. This method encourages innovative thinking and can be applied in various fields, including business, education, and design, making it a versatile tool for brainstorming and decision-making.
