Unlike document-based approaches where system specifications are scattered across numerous text documents, [[Spreadsheet|spreadsheets]], and [[Diagram|diagrams]] that can become inconsistent over time, MBSE centralizes information in interconnected models that automatically maintain relationships between system elements. These models serve as the authoritative source of truth for [[Systems design|system design]], enabling automated verification of requirements, real-time impact analysis of proposed changes, and generation of consistent documentation from a single source. This approach significantly reduces errors from manual synchronization, improves traceability between requirements and implementation, and facilitates earlier detection of design flaws through simulation and analysis.
The MBSE approach has been widely adopted across industries dealing with complex systems development, including aerospace, defense, rail, automotive, and manufacturing.<ref>{{Cite journal |last1=Nouacer |first1=Réda |last2=Djemal |first2=Manel |last3=Niar |first3=Smail |last4=Mouchard |first4=Gilles |last5=Rapin |first5=Nicolas |last6=Gallois |first6=Jean-Pierre |last7=Fiani |first7=Philippe |last8=Chastrette |first8=François |last9=Lapitre |first9=Arnault |last10=Adriano |first10=Toni |last11=Mac-Eachen |first11=Bryan |date=2016-11-01 |title=EQUITAS: A tool-chain for functional safety and reliability improvement in automotive systems |url=https://www.sciencedirect.com/science/article/pii/S0141933116301156 |journal=Microprocessors and Microsystems |language=en |volume=47 |pages=252–261 |doi=10.1016/j.micpro.2016.07.020 |issn=0141-9331|url-access=subscription }}</ref><ref>{{Cite book |last1=Chen |first1=B. |title=2018 International Conference on Intelligent Rail Transportation (ICIRT) |last2=Zhang |first2=S. |last3=Wang |first3=B. |date=December 2018 |isbn=978-1-5386-7528-1 |pages=1–5 |chapter=A Case Study of MBSE Method Used in the EMU Train Design |doi=10.1109/ICIRT.2018.8641645 |chapter-url=https://ieeexplore.ieee.org/document/8641645 |s2cid=61807576}}</ref><ref>{{Cite book |last1=Weiss |first1=E. |title=MILCOM 2019 - 2019 IEEE Military Communications Conference (MILCOM) |last2=Chung |first2=L. |last3=Nguyen |first3=L. |date=November 2019 |isbn=978-1-7281-4280-7 |pages=65–69 |chapter=A MBSE Approach to Satellite Clock Time and Frequency Adjustment in Highly Elliptical Orbit |doi=10.1109/MILCOM47813.2019.9020875 |chapter-url=https://ieeexplore.ieee.org/document/9020875 |s2cid=212648120}}</ref><ref>{{Cite book |last1=Hause |first1=M. |title=2018 13th Annual Conference on System of Systems Engineering (SoSE) |last2=Hummell |first2=J. |last3=Grelier |first3=F. |date=June 2018 |isbn=978-1-5386-4876-6 |pages=365–371 |chapter=MBSE Driven IoT for Smarter Cities |doi=10.1109/SYSOSE.2018.8428705 |chapter-url=https://ieeexplore.ieee.org/document/8428705 |s2cid=51976927}}</ref> By enabling consistent system representation across disciplines and development phases, MBSE helps organizations manage complexity, reduce development risks, improve quality, and enhance collaboration among multidisciplinary teams.
