INTRODUCTION

CORE DEFINITION

Pattern reuse and integration treats validated design patterns as components and builds larger systems by combining, layering, and coupling them. The core proposition is that a pattern carries proven behaviour and known trade-offs, so composing existing patterns reduces the trial-and-error cost of constructing complex systems. The key qualification is that patterns have contexts and responsibilities: combining patterns whose roles conflict creates coupling that is worse than the problem the reuse was meant to solve.

SCAFFOLDING EFFECT

Reduce cognitive load

- Pattern library: maintain a catalogue of patterns annotated with the situations each one actually fits well. - Selection by need: choose patterns from the stated requirement rather than from mere familiarity. - Interface definition: specify how the chosen patterns interact before you integrate them together.

Anchor fast decisions

Each pattern packages a solution together with the trade-offs it accepts, so reusing one imports known behaviour instead of discovering it again. Integration works when the interfaces between patterns are explicit, because the composition's behaviour is then predictable from the parts. Where responsibilities overlap, the interaction becomes the source of defects rather than the parts themselves.
