Product Design for Variants
Recognizing the need to design for product variants and the best methods to manage variants is critical to product development success over time. Variant management is how you organize the list of feature variants and put them into products. With new product development projects, planning for future variants is not typically done at the beginning. In this article. Joanne Scouler and Marty Bakal explain how to get started with variants. They illustrate their points with examples from Eaton Corporation's experience in developing variants of transmissions for heavy-duty hybrid vehicles. The authors also describe how various Rational software products can help.

Safety-related software development using a model-based testing workflow
Developing safety-related software, where failure can result in injury or loss of life, such as in airplanes, automobiles, trains, or medical devices, requires extra care and effort. The delivery of safe code that is compliant with strict development standards and guidelines such as DO-178C, DO-178B, ISO 26262, IEC 61508, or IEC 62304, can result in increased time and cost of the project. This article describes how to use the Rhapsody Reference workflow included with the IBM Rational Rhapsody Kit for ISO 26262 and IEC 61508 for development of safety-related applications. You will learn about the Rhapsody Reference workflow, and how model-based testing with the Rational Rhapsody TestConductor Add On can be used to verify the model and the generated code. It reduces the time to deliver high-quality software yet still complies with safety standards.

Cyber security for the nuclear energy industry
When deploying software based systems, such as, digital instrumentation and controls for the nuclear industry, it is vital to include cyber security assessment as part of architecture and development process. When integrating and delivering software-intensive systems for the nuclear industry, engineering teams should make use of a secure, requirements driven, software development life cycle, ensuring security compliance and optimum return on investment. Reliability protections, data loss prevention, and privacy enforcement provide a strong case for installing strict cyber security policies.

Cut complexity in software and systems with Collaborative Design Management
Complexity is the biggest challenge in delivering innovative products, systems, and applications today. To address this issue, IBM Rational software promotes a model-based approach that improves quality and increases collaboration across the entire team. Our new Collaborative Design Management (CDM) features extend these capabilities so you can involve stakeholders from across the organization and beyond in the design process and improve the integrations of designs to artifacts across the software development lifecycle.

Developing smarter Ada applications using a model-driven approach with UML 2.0 and Ada 2005 interfaces
The Unified Modeling Language (UML) 1.x offered developers the ability to visualize how classes are coupled. A key enhancement to UML 2.x is to improve support for modeling large-scale systems, including the ability to hierarchically decompose systems into parts with clear ports and interfaces. However, since a UML 2.x port can be contracted to provide any number of interfaces in UML 2.x, those developers using Ada 95 have a number of implementation challenges when mapping UML interfaces to code. This article illustrates how these challenges can be resolved utilizing Ada 2005 interfaces. The article will also show how the power of UML 2.x ports and interfaces now supported by the IBM Rational Rhapsody solution and highlight the benefits of using this environment, including the clear separation of components and how components can be re-used in multiple assemblies, leveraging the Rhapsody tool to automatically generate the wiring code.

Domain specific modeling with IBM Rational Rhapsody
Learn how to use domain specific language (DSL) modeling with IBM Rational Rhapsody. Domain specific modeling allows users to extend standard modeling notations with their own domain terminology. In this demo, domain specific model elements and a new kind of diagram are defined using a UML profile within Rational Rhapsody. The UML profile is then applied to a selected example, and a domain specific model is created.
