This document discusses Systematic Inventive Thinking (SIT), a method developed from TRIZ (the Russian acronym for "Theory of Inventive Problem Solving") for systematically producing new ideas, creativity, innovation, and problem solving. SIT was adapted from TRIZ by an Israeli group and includes techniques like subtraction, multiplication, division, task unification, and attribute dependency to help solve problems in a scientific manner by modifying existing solutions in various ways.
