Style Guides
This page is dedicated to promoting the development and adoption of Model-Based Systems Engineering (MBSE) Style Guides within the US Air Force. Our goal is to establish a uniform MBSE style guide that provides a better foundation for model development, mitigating confusion incurred due to model translations and deliverables.
SSC MBSE Style Guide Version 1.1
We are pleased to announce the release of the SSC MBSE Style Guide Version 1.1, intended for use by any program within the Air Force. The purpose of this Style Guide is to establish a set of validation rules that enable and verify proper MBSE model development. The scope of this Style Guide is to define validation rules to develop SysML-compliant MBSE models for utilization across the Air Force enterprise.
The SSC MBSE Style Guide Version 1.1 is designed to provide critical MBSE government guidance, and its adoption is encouraged across the Air Force. This Style Guide does not dictate when diagrams should be used in models or what diagrams to request in a contract, but rather provides rules that can be validated for elements used within a model.
The Point of Contact for the SSC Style Guide is listed within the document.
Capability Development MBSE Guidebook
The Air Force Strategic Development Planning and Experimentation (SDPE) Office created a Model Based Systems Engineering (MBSE) Guidebook for early capability development that provides knowledge on the application of MBSE to the process of early systems engineering.
This guidebook is the culmination of an effort by the SDPE Office to address a complex, ill-defined process using MBSE and a phased base approach called the Capability Development Process Framework. While this is specific to the early systems engineering problem set, the guidebook addresses digital engineering concepts that a program could use in other acquisition process challenges.
The method begins with a notional assessment of cost and capability for solution types to meet a project goal. Next, promising solution types are down selected and refined into concept types. These concept types are defined and analyzed in terms of notionally assessed Performance, Effectiveness, Risk, Cost, Schedule, and Suitability. Modeling, Simulation, and Analysist tools are coupled with the MBSE system architecture to refine the measures that define a concept’s capability.

Other MBSE Style Guides
In addition to the SSC MBSE Style Guide, there are other style guides used across the Department of the Air Force. These include:
- AFLCMC Style Guide.mdzip: This Cameo model will help aid your adoption of the AFLCMC Style Guide, which is based on 9 different style guides, including the SSC Style Guide. This Style Guide is developed and maintained by the AFLCMC Style Guide Working Group, heading by Keith Siders, AFLCMC/EZSI.
- DOD Mission Architecture Style Guide: The development of this guide was led by the Deputy Assistant Secretary of Defense (DASD) for Mission Integration (MI) directorate within the Office of Defense for Research and Engineering, Mission Capabilities (OUSD R&E / MC) with support from the Department of Defense Mission Engineering Practitioners Forum and external ME stakeholders. The MASG will aid model-based systems engineers and architects in the creation, presentation, and analysis of model-based mission architectures. The style guide was developed to synergize the creation and sharing of mission architectures across the Department of Defense (DoD). The MASG focuses on mission architecture development as a fundamental element of Mission Engineering as defined in the MEG 2.0.
- Space Warfighter Analysis Center (SWAC) Style Guide: An exemplar style guide that walks through the creation of Systems Modeling Language Block Definition Diagrams and State Machine Diagrams, presenting rules for the use of these two types of diagrams.
AFRL_RV Style Guide v1.3: A style guide intended to act as the starting point for any model involving space vehicles, providing a foundation for model development and enabling continual integration of project models into an enterprise architecture.
Collaboration and Knowledge Sharing
This page aims to facilitate collaboration and knowledge sharing among stakeholders, including program offices, industry partners, and government entities, to promote the development and adoption of MBSE style guides. We encourage feedback, suggestions, and contributions to ensure the continuous improvement of our MBSE style guides.
By promoting the use of MBSE style guides, we can ensure better model interoperability, improved systems engineering practices, and enhanced collaboration across the Air Force enterprise.
This continuous learning module provides key information, from a Systems Engineering perspective.

Recommended for: Foundational Functional-Specific Digital Awareness Education & Training
This Model-Based Systems Engineering (MBSE) course and the Digital Thread courses featured earlier in this specialization bring together the concepts from across digital manufacturing and design, forming a vision in which the geometry of a product is just one way of describing it. MBSE is where the model resulting from the evolution of system requirements, design, analysis, verification, and validation activities is the focus of design and manufacturing. Students will gain an understanding of systems engineering, the model-based approach to design and manufacturing, the Digital Twin, and a roadmap toward a model-based enterprise.
