System Design and Software Design using UML and SysML

In today’s competitive environment, organizations are struggling to deliver more complex systems in less time and with fewer staff. Whether for composite products, large-scale control systems or distributed IT applications, adopting a more visual, automated and reliable process can help you design the right system--the first time.

Successful system design and software design using the Unified Modeling Language™ (UML™) version 2.1, the latest industry standard visual modeling language, and the derived Systems Modeling Language (SysML) for systems engineers, can increase productivity, minimize development costs, and shorten time to market.

System design and software design should support comprehensive modeling of large and complex systems-of-systems, resulting in precise, easy-to-understand, and unambiguous specifications. And systems engineers should be able to specify not only the structure but also the behavior of the system under development.

What's more, systems engineers should be able to simulate the specifications to verify and validate the system and demonstrate its behavior to end-users and other stake-holders at an early stage.

To ensure that models conform to the system requirements, systems engineers should be able to view textual requirements from within their design environment. With visibility of requirements, engineers can quickly assess the impact of any requirements changes, as well as create traceability links between those user/system requirements and analysis models, and the UML or SysML system design elements that satisfy them.

To increase productivity, system designers need to correct mistakes early through comprehensive and immediate syntax and semantics checking.

To accelerate the development process, a design solution should automate the transition from design to implementation by generating executable software from the design models.
