This article is intended to provide a non-exhaustive presentation of SysML including some background about Systems Engineering and SysML, and a review of each SysML diagram and modelling techniques.  \nSystems Engineering  \nSystems Engineering (SE), is an approach and discipline to deal with complex systems realised through software and hardware solutions.  \nSystems Engineering applies to the following areas and industries: embedded systems (e.g. audio and video encoding/decoding, set top box), automotive, rail, aerospace, military, telecom, healthcare, energy, etc.  \nSystems Engineering (SE) relies on modelling and simulation methods to validate requirements or to evaluate the system. Therefore modelling is common practice in SE to deliver functional specifications, data flow description, or system structure definitions through the use of modelling techniques such as:  \n Data Flow Diagram (DFD) to define the data going through a system, and any processing required  \n Functional Flow Block Diagram (FFBD), similar to the UML activity diagram  \nSpecifications produced with SE often result from a document-based approach, producing a large amount of documents with various types of diagrams or notations, sometimes used in an inconsistent manner.  \nThe suggested alternative is the use of a model-based approach, usually referred as the “ModelBased Systems Engineering” or MBSE, to deliver a consistent set of system views, stored and managed in a repository such as Sparx Enterprise Architect.  \nThe model-based approach leads to a structured set of models, representing and specifying the system at various levels of granularity such as the operational, functional, and technical aspects. Modelling the system helps in managing its complexity, since each model and diagram provides an abstracted view and definition of the system (or part of it) .  \nSysML background  \nUML is the standard modelling language used in the software community. Even though UML should be sufficient to address Systems Engineering needs through its wide range of notations, it is recommended to adapt it with extensions defined with “UML profiles”. As regards, several projects have been carried to create UML profiles for specific SE domains, e.g. MARTE and System on a Chip.  \nThe decision to define a general-purpose modelling language based on UML and dedicated to SE was initiated in 2001 by the INCOSE (International Council on Systems Engineering) that got in touch with the OMG (Object Management Group) to form the Systems Engineering Domains Special Interest Group (SE DSIG) . The goal of such language is defined as follows: “A standard modelling language for systems engineering to analyze, specify, design, and verify complex systems, is intended to enhance systems quality, improve the ability to exchange systems engineering information amongst tools, and help bridge the semantic gap between systems, software, and other engineering disciplines”.  \nThe INCOSE and the OMG were joined by members of the industry (BAE, Motorola, Boeing…), modelling tools vendors (IBM, Sparx Systems…), universities and organizations to define the systems modelling language SysML.  \n 07/2006 : SysML is officially adopted by the OMG  \n 09/2007 : SysML v1.0  \n 12/2008 : SysML v1 .1  \n 06/2010 : SysML v1.2 (current version)  \nSysML overview  \nSysML is based on UML and involves modelling blocks instead of modelling classes, thus providing a vocabulary that’s more suitable for Systems Engineering. A block encompasses software, hardware, data, processes, personnel, and facilities.  \nAs specified on the following diagram, SysML reuses a subset of UML2 (UML4SysML), and defines its own extensions.
