The nine windows technique, also known as 9 windows, 9 boxes, 9 screens, multiscreen diagram, or system operator tool is a creative problem-solving technique that analyzes a problem across time and relative to its place within a system.
[1][2][3][4] The approach is based on the Theory of Inventive Problem Solving (TRIZ) and involves creating a 3 × 3 matrix and placing the current problem in the center.

The 3 × 3 matrix is divided into three problem-solving levels:[5] This engineering-related article is a stub.
