P

Perspective

Reframe problems by shifting viewpoints and identifying foundational truths.

IN

Inversion

Improve by removing, reversing, or stress-testing assumptions.

CO

Composition

Combine elements so the integrated value exceeds the sum of parts.

DE

Decomposition

Break problems into factors, layers, and independent subproblems.

RE

Recursion

Improve iteratively through feedback, reflection, and self-referential refinement.

SY

Systems

Identify leverage points, feedback structures, and emergent dynamics in whole systems.
