Modularity
Definition
Modularity breaks down a system into clearly defined parts.
Modules bundle related tasks and communicate via defined interfaces. Good boundaries limit which changes affect other parts.
Simply explained
An interchangeable building block can be changed without rebuilding the entire structure.
Why it matters in practice
This facilitates maintenance, testing, and the gradual introduction of new AI features.
Example from business
Hypothetical example: A company replaces its model provider behind an unchanged interface.
Limits and pitfalls
- Too many small modules increase coordination and connection effort.
Origin & history
The principle is fundamental for software architecture and system design.
Use in mid-sized companies
- SMEs can separate central business logic from interchangeable services.
Frequently asked questions
