CORE DEFINITION

A structured brainstorming method developed by Yasuo Matsumura at Clover Management Research in Japan, built on the nine-cell grid. A central theme sits in the middle of a three-by-three grid, eight surrounding cells hold related subthemes, and each subtheme then becomes the center of its own grid with eight further cells. A full two-level expansion produces sixty-four idea cells. The method's defining constraint is that the grid must be filled, which forces thinking past the first few obvious answers. It generates material for evaluation but performs no convergence itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Forced Expansion: fill the empty cells so thinking cannot stop at the first few answers. - Coverage Check: use the eight spokes to verify no major dimension of the theme was skipped. - Meeting Structure: give a group a shared grid so parallel contributions land in comparable slots.

Anchor fast decisions

Unstructured ideation decays because the easy answers arrive first and the group mistakes that early fluency for exhaustion. A fixed grid converts an open task into a completion task, and an unfilled cell is a visible, uncomfortable gap that supplies the pressure to keep generating. Expanding each subtheme into its own grid also forces depth, since the second level cannot be reached without committing to a first, which prevents the common pattern of listing eight topics and elaborating none. The structure trades process flexibility for thoroughness of output.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
