A Practical Guide to SysML: The Systems Modeling Language is a comprehensive guide to SysML for systems and software engineers. It provides an advanced and practical resource for modeling systems with SysML. The source describes the modeling language and offers information about employing SysML in transitioning an organization or project to model-based systems engineering. The book also presents various examples to help readers understand the OMG Systems Modeling Professional (OCSMP) Certification Program. The text is organized into four parts. The first part provides an overview of systems engineering. It explains the model-based approach by comparing it with the document-based approach and providing the modeling principles. The overview of SYsML is also discussed. The second part of the book covers a comprehensive description of the language. It discusses the main concepts of model organization, parametrics, blocks, use cases, interactions, requirements, allocations, and profiles. The third part presents examples that illustrate how SysML supports different model-based procedures. The last part discusses how to transition and deploy SysML into an organization or project. It explains the integration of SysML into a systems development environment. Furthermore, it describes the category of data that are exchanged between a SysML tool and other types of tools, and the types of exchange mechanisms that can be used. It also covers the criteria that must be considered when selecting a SysML. Software and systems engineers, programmers, IT practitioners, experts, and non-experts will find this book useful.

"SysML is the new industry-standard language designed specifically to support modern systems engineering. I cannot imagine a better way to learn SysML than to read about it from the masters: Friedenthal, Moore, and Steiner led the design of this important new language and now cap that effort with this comprehensive and highly readable guide for both novices and experts." —Bran Selic, Malina Software Corporation
"This book is just the ticket you need to get started on the road to adopting standards-based, model-based systems engineering (MBSE) methods. The authors have done an outstanding job in providing detailed coverage of the SysML language and semantics supported through worked examples." —Jeff Estefan, Principal Engineer, NASA's Jet Propulsion Laboratory
"The authors of this book have been invovlded in SysML development since its inception, and have the understanding necessary to explain it clearly. In particular, the activity diagrams chapter accurately and concisely describes the SysML extensions to UML for functional flow modeling."—Conrad Bock, OMG Lead for Activity Modeling in SysML
