Systembyggande

Systembyggande is the discipline and practice of designing and integrating complex systems by coordinating hardware, software, people, and processes to meet defined objectives and constraints. It takes a holistic perspective, focusing on the system as a whole rather than on individual components, and considers how elements interact across the lifecycle.

Key activities include requirements elicitation and management, definition of system architecture and interfaces, integration planning, verification and validation, and lifecycle management from conception to disposal. Systembyggande emphasizes traceability between needs, designs, and delivered capabilities, as well as managing risk, cost, and schedules in multi-disciplinary contexts.

Methods and approaches commonly used in systembyggande include model-based systems engineering (MBSE), architecture frameworks and viewpoints, and iterative or incremental development. Standards such as systems life cycle processes and architecture description help align practices across organizations. The V-model and other systems engineering processes are often employed to structure activities from requirements to testing.

Applications span industries such as manufacturing, transportation, defense, telecommunications, energy, and public services. In Sweden and other Nordic countries, systembyggande is applied to large-scale projects where reliability, safety, and interoperability are critical, often involving collaboration across suppliers, integrators, and operators.

In summary, systembyggande provides a structured approach to creating complex, integrated systems that fulfill strategic objectives while managing complexity, risk, and lifecycle implications.
