modulaarsuse

Modulaarsuse (modularity) is the degree to which a system is decomposed into modules—discrete units with defined responsibilities and interfaces. Good modularity enables encapsulation and independent evolution of parts.

Domains: In software engineering, modularity structures code into components with specific duties and minimal dependencies. In hardware, product lines, or organizational design, modularity supports reuse and customization. In biology and neuroscience, modularity describes specialized subsystems or cortical areas. In network analysis, modularity (often denoted Q) measures how well a network divides into communities with dense internal links and sparse external links.

Benefits and trade-offs: advantages include easier maintenance, scalability, parallel development, testability, and resilience; the approach also supports replaceability and reusability. Challenges include selecting boundaries and granularity, managing interfaces and dependencies, potential performance costs, and possible over-modularization.

Achieving good modulaarsuse requires clear interface contracts, cohesive modules with single responsibilities, loose coupling, and standardized communication protocols. The concept is widely used in software architecture, systems engineering, and organizational design.
