Modular Decomposition
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
Breaking a complex whole into independent, manageable units, each of which can be understood, tested, or replaced on its own. Facing a large system, the approach is to split it into modules, tackle them one by one, and then work out the relationships between them. Unit chunking and unit verification are treated as the same family of techniques.
SCAFFOLDING EFFECT
Reduce cognitive load
- Boundary setting: define the overall boundary and goal before splitting anything. - Cohesive split: carve units so each one is internally cohesive and self-contained. - Interface definition: specify how the units connect, then integrate them deliberately.
Anchor fast decisions
Decomposing a complex whole into units with clear boundaries that can be understood, tested, or replaced independently lowers cognitive load. Understanding the relationships between units through their interfaces then turns the pieces back into a whole, dividing the large problem into small ones.
