modulaarsele

Modulaarsele is a term found in Estonian technical discourse to denote the practice and philosophy of modularity in system design. In practice, modulaarsele describes designing with interchangeable components that interact through stable interfaces, enabling independent development, testing, and replacement of parts without affecting the whole.

Origin and usage: The root is modulaarne (modular). The suffix -sele marks the allative case in Estonian, used here to express the direction or approach toward modularity, i.e., moving toward modular design. The term is primarily used in engineering, software architecture, and product development discussions in Estonian-language contexts and may appear in curricula or standards that emphasize modular thinking.

Core principles include separation of concerns, loose coupling, high cohesion, clear interfaces, and composability. A modulaarsele approach favors creating generic, well-documented modules with defined inputs and outputs and limiting cross-module dependencies. It also supports iterative development, parallel teams, and easier maintenance.

Applications span software (microservices, plugin architectures), hardware (modular hardware platforms), product design (modular furniture or electronics), and urban planning (modular construction concepts).

Advantages often cited are scalability, adaptability to changing requirements, easier testing, and the ability to reuse components across projects. Limitations include potential over-engineering, interface management overhead, version compatibility issues, and the need for disciplined governance to maintain module boundaries.
