Systems engineering is defined as an “interdisciplinary approach to the development and management of complex systems”. It combines engineering, management, and analysis to enable the understanding, specification, design, and validation of systems.

The most important goals of systems engineering are to meet customer requirements, ensure system reliability and safety, optimize system performance, meet cost and time constraints, and manage risks and uncertainties.

MBSE offers several advantages compared to traditional systems engineering methods: it enables more holistic and precise modeling and analysis of complex systems, improves communication between project participants, increases efficiency through reusability of models, and promotes traceability and transparency of the system development process.

The main components of a systems engineering process include requirements analysis, system architecture, system design, system integration, verification and validation, as well as system maintenance and improvement.

Requirements analysis is an essential part of systems engineering. It includes identifying, specifying, prioritizing, and validating system requirements. MBSE supports this process by enabling the creation and management of requirements models that provide better comprehensibility and traceability.

Typical modeling languages used in the MBSE are, for example, the Systems Modeling Language (SysML) and the Unified Modeling Language (UML). These languages provide a standardized notation for describing system models, including structure, behavior, and interactions.

Typical modeling languages used in the MBSE are, for example, the Systems Modeling Language (SysML) and the Unified Modeling Language (UML). These languages provide a standardized notation for describing system models, including structure, behavior, and interactions.

Various tools and technologies are used to implement MBSE, including specialized modeling tools, requirements management software, versioning systems, and collaboration tools. These support the creation, management and analysis of system models.

The successful transition from traditional engineering methods to MBSE requires extensive planning and training of project staff. Companies should set clear goals, allocate resources, and take a step-by-step approach to reap the full benefits of MBSE.

Various challenges can arise during the introduction of Model-Based Systems Engineering (MBSE). Here are some of these challenges and possible solutions to address them. Since we at Two Pillars accompany you in the introduction of systems engineering, we have a lot of experience in this change process.
Cultural challenges: The introduction of MBSE may require a change in work culture and acceptance of new modeling and collaboration methods. This may be met with resistance or uncertainty from project stakeholders. Comprehensive training and awareness among team members about the benefits of MBSE helps to overcome these cultural challenges.
Complexity of modeling: MBSE involves the creation and management of complex system models that cover various aspects and domains. Mastery of the modeling language and knowledge of the best modeling techniques can be helpful in addressing this challenge. Training, training materials and experienced modelling experts can help with this.
Collaboration and communication: MBSE promotes collaboration and communication between different departments and stakeholders. Clear communication of goals, roles and responsibilities as well as the establishment of appropriate communication channels and processes are crucial to facilitate cooperation and avoid misunderstandings.
Traceability and transparency: Traceability of requirements, models, and other artifacts is an important aspect of MBSE. The use of appropriate tools and methods for linking and tracking artifacts can help ensure transparency and traceability. It is important to establish clear guidelines and standards for the management and documentation of artifacts.
Change Management: The introduction of MBSE can entail changes in a company’s processes, structures and ways of working. A comprehensive change management program that engages employees, reduces resistance, and provides support can help ease the transition and ensure a successful adoption of MBSE.

MBSE supports the validation and verification of system requirements by enabling requirements to be converted into models and verified through simulations. This allows early identification of potential problems and facilitates traceability between the requirements and the models created.

Modeling and integrating hardware and software into MBSE can be challenging, as different modeling languages and domains are involved. It requires the coordination and exchange of information between the disciplines involved to ensure a consistent and complete representation of the system.

MBSE enables the analysis and optimization of complex system architectures by using different models to visualize and evaluate the impact of changes. This makes it easier to identify bottlenecks, optimize performance and reliability, and evaluate alternative design options.

Best practices for managing and updating models and modeling tools in MBSE projects include establishing an appropriate version control system that sets clear guidelines for model management, as well as training team members in the effective use of the tools and methodologies.

MBSE supports the entire lifecycle of a system by enabling modeling and analysis at different stages. During design, MBSE can be used to optimize system architecture and validate requirements. During implementation, it supports the verification and validation of the system. In operation and maintenance, it allows for better diagnosis of problems and change management.

A boundary diagram is a type of diagram used in systems engineering to define the boundaries of a system and represent its interactions with the environment. It is often used in conjunction with requirements analysis and system architecture.
The boundary diagram shows the external entities or systems with which the system under consideration interacts. It graphically represents the interfaces between the system and its environment. These interfaces can be physical, logical or functional in nature and can be illustrated, for example, by data flows, communication channels or signals.
The boundary diagram allows stakeholders to understand the context boundaries of the system and identify the inputs and outputs of the system. It facilitates communication and understanding of system boundaries both within the development team and with external stakeholders. In addition, the boundary diagram can serve as a basis for identifying system requirements resulting from interactions with the environment.
Overall, the boundary diagram serves to clearly define the system and visualize its relationships with the environment, which in turn contributes to the development of a consistent and complete system architecture.
