MBSE
Published in Joseph Eli Kasser, Systems Engineering, 2019
Perceptions from the Structural HTP provide a number of different definitions of MBSE, including: ‘MBSE is the formalized application of modelling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases’ (INCOSE 2007, p. 15).‘MBSE is fundamentally a thought process. It provides the framework to allow the systems engineering team to be effective and consistent right from the start of any project’ (Long and Scott 2011, p. 65).‘MBSE is a systems engineering paradigm that emphasizes the application of rigorous visual modelling principles and best practices to systems engineering activities throughout the [system development lifecycle] SDLC’ (MBSE 2011).
Model-based systems engineering
Published in Adedeji B. Badiru, Systems Engineering Models, 2019
A good model is a good guide for process execution. Model-Based Engineering (MBE) is a general approach to engineering that uses models as an integral part of the technical baseline that includes the requirements, analysis, design, implementation, and verification of a capability, system, and/or product throughout a systems life cycle. Model-Based Systems Engineering (MBSE) focuses MBE specifically on the approach of systems engineering. MBSE is the formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases. MBSE provides significant opportunities for improved productivity, efficiency, effectiveness, and product quality. This is a relatively new approach to the application of systems engineering and has received growing attention and acceptance.
A Model-Based Approach to Investigate Emergent Behaviors in Systems of Systems

Model-Based Systems Engineering (MBSE) enables a means to capture the interactions and connectivity among components within a system of systems. As outlined by Delligatti, in order to implement an MBSE approach, the user needs to employ a language, method, and tool [29]. The Object Modeling Group (OMG) definition of Unified Modeling Language (UML) [2] and the associated dialect of Systems Modeling Language (SysML) [3] provide a means for standard definition of syntax, semantics, and exchange of behavior models and associated diagrams, including activity diagrams, sequence diagrams, state charts, and use cases. The elements SysML describe the model structure, behavior, requirements, and constraints using a semi-formal modeling language that aligns the grammar, or a set of rules used to depict the system. As illustrated in Figure 19.1, SysML depicts the following aspects of the system, [3]:
Examples of performance requirement derivation through modelling and simulation in complex projects

MBSE retains all of the methodologies and practices of traditional systems engineering, but assures the consistency, alignment, and version control of the many multiple live artefacts generated through the use of a relational database that is typically referred to as the MBSE model of the system. The MBSE model maintains and manages all of the relationships and interconnectedness of the design aspects developed and represented throughout the various artefacts and documentation of the entire systems architecture in a standardised model schema (Madni and Sievers 2018). MBSE automates the tracing of cascading impacts of design negotiations throughout the entire architecture and so reduces human error. The MBSE approach for developing and maintaining a system model through the employment of a relational database is distinct from the general use of models to support engineering activities, which has been common practice for decades.
A system modeling process based on SysML to support data consistency across system requirement, function, and solution model layers

The MBSE approach is emerging as an important practice in the development of complex technical systems to enhance productivity and improve communication among the system development teams (Beery 2019; Stirgwolt, Mazzuchi, and Sarkani 2022). Ideally, MBSE should formalise the application of modeling to support the system requirements definition, design, analysis, and verification & validation activities throughout the system development process and among all stakeholders (Walden et al. 2015). SysML is a general-purpose graphical modeling language that defines and represents system elements such as system requirements, functions, physical structure, and behaviours throughout the development process. The system model is the artifact of modeling and serves as a central platform that enables these abstract system elements to be linked with each other (Friedenthal, Moore, and Steiner 2015).
The Effects of Organizational Structure on MBSE Adoption in Industry: Insights from Practitioners
Published in Engineering Management Journal, 2023
Kaitlin Henderson, Alejandro Salado
Model-Based Systems Engineering (MBSE) is the result of Systems Engineering (SE) practice shifting from a document-based to model-based paradigm as part of the larger digital engineering transformation happening in the industry (Papke et al., 2020). MBSE has been reported to be difficult to adopt in various industry settings (Broodney et al., 2012; Chami & Bruel, 2018; Papke et al., 2020; Wang et al., 2016; Weilkiens et al., 2016). One critical barrier to adoption is the difficulty of adopting and implementing MBSE itself (Huldt & Stenius, 2019). One reason for this difficulty may be the two different contexts MBSE can be viewed through: as both a process and a method (Henderson & Salado, 2021). MBSE can be classified as a method of performing the SE process, as it describes how SE tasks should be carried out. But MBSE is also a process itself because it describes what activities are to be performed without specifying how. So not only does MBSE need to be incorporated into existing organizational processes as a new method for SE, it has its own considerations that need to also be addressed as its own process. This translates to multiple perspectives and decisions that must be addressed at different levels of an organization when adopting MBSE. Because MBSE has to be incorporated into existing organizational processes (which ideally involves more than just the SE discipline), it is beneficial for the organization where it is being adopted to be invested in its successful implementation (Trauth et al., 2017).
