Systematic Inventive Thinking, SIT

CORE DEFINITION

Systematic inventive thinking, usually abbreviated SIT, is a structured creativity method built on the closed-world assumption, meaning that innovation must draw only on components and attributes already present in the problem situation. Within that boundary it applies five templates: subtraction, division, multiplication, task unification, and attribute dependency. The core proposition is that the closed-world restriction raises the relevance and feasibility of the ideas generated, because every concept is composed of existing parts rather than requiring unavailable resources. The key qualification is that the templates are prompts rather than guarantees, and their output still requires judgment, filtering, and prototyping before it becomes a product decision.
