Systems engineering
Systems engineering is an interdisciplinary approach and a set of tools aimed at ensuring the successful implementation of complex systems. According to the definition by INCOSE (International Council on Systems Engineering), systems engineering provides a holistic, integrative approach to the development, implementation, operation, and retirement of systems.
According to the ISO/IEC/IEEE 24765:2010 standard: Systems engineering is an interdisciplinary approach governing the total technical and managerial effort required to transform a set of customer needs, expectations, and constraints into a viable system solution and to support that solution throughout its life cycle.
Systems engineering is based on the principles of the systems approach and systems thinking.
Purpose and Goals
The main goals of systems engineering are to:
- provide reliable and consistent guidance for the development of complex, multi-level systems;
- integrate all engineering disciplines and specializations within a single project;
- focus on customer needs, operational conditions, and the system life cycle;
- manage system complexity and reduce risks.
Within the context of systems engineering, a system is viewed as a set of interconnected elements (technical, software, organizational, human) that interact to achieve a common goal.
Features of Systems Engineering
- Focus on the system as a whole, rather than on individual components.
- Integration of requirements, architecture, verification, validation, and support.
- Bridging the gap between different engineering and management disciplines.
- Consideration of the system life cycle—from conceptual design to disposal.
- Management of interactions and dependencies between subsystems.
- Balancing technical solutions with constraints (cost, time, resources, regulatory requirements).
Relationship with Project Management
Systems engineering is closely related to project management and is an integral part of project leadership. It is essential for:
- planning and directing engineering efforts;
- integrating engineering activities into the overall project context;
- coordinating among stakeholders;
- ensuring requirements traceability and compliance with project goals.
Application Examples
Systems engineering is applied in the following areas:
- aviation and aerospace engineering;
- defense and military systems;
- energy and nuclear industry;
- transportation systems;
- large-scale IT systems and infrastructure projects.
