Although software is the value driver behind business success, because of consumer demands and the faster pace of technology changes, the software component in smarter products presents challenging new layers of complexity for systems development teams. In fact, this complexity seems to be the arch enemy of product innovation. We frequently hear statements from practitioners such as these:
"We will need 2 weeks to understand the impact of a change across the engineering teams." — Systems Engineer
"It could take me days just to find all the software modules, design elements, and requirements related to the defect the test team just found." — Software Engineer
"I can't easily tell which version of the control software is designed for which version of the sensors." — Electrical Engineer
"We've changed supplier for a part, and it'll take me ages to determine any impact on the systems design or ability to meet requirements." — Mechanical Engineer
Today's product and systems teams must learn to manage these new forms of complexity to deliver product innovation and gain a competitive advantage. This article introduces new IBM® Rational® solutions to help you meet this challenge.
The challenges of smarter product delivery
To deliver today's smarter products, engineers and manufacturers must unify embedded software development expertise with agile systems engineering capabilities that cover specification and design. But this seems like a tall order. And how, exactly, does this lead to innovation?
Smarter products are necessarily complex. They require collaboration between multiple engineering disciplines. The software component of product design presents unique challenges compared to engineering fields grounded in the physical world. Consider these issues: the environment in which smarter products must operate is usually not fully known at design time, and software designs typically change much faster than physical designs.
Overcoming these challenges demands increased agility in software development. So the question is: Where should product development teams focus their efforts to conquer complexity and deliver innovation? IBM Rational believes they should focus on the areas that actually encourage innovation. The best practices governing systems engineering and embedded software development are areas that hold great promise for organizations that want to differentiate themselves from competitors.
Adopting a systems approach
Adopting systems engineering practices as an antidote to traditional development practices, which have been primarily concerned with physical design and the bill of materials (BOM) as outputs, can seem like a daunting task. But product development must evolve if product teams are to succeed in exploiting the many business opportunities arising in this age of software-driven innovation. By viewing product development from a systems perspective, teams benefit from a new top-down, holistic, domain-integrated view, rather than the bottom-up assembly of parts. True, the details of the physical design and the BOM are not going away, but they need to be understood through the lens of systems engineering practices.
Developing a competency in embedded software development is vital for teams to avoid being left behind in the next wave of product innovation. Integrating electrical, mechanical, and software engineering through a systems approach, with linked lifecycle data support, vastly increases understanding of data relationships and more effective collaboration across engineering disciplines.
IBM Rational solutions are founded on an open, federated approach to integrating engineering disciplines. Based on Open Services for Lifecycle Collaboration (OSLC) standards, the Rational Solution for Systems and Software Engineering offers next-generation product development that leverages linked lifecycle data as the primary mechanism for integration.
New IBM Rational solutions for systems teams
Greatly enhanced for the fall 2012 launch, the IBM Rational Solution for Systems and Software Engineering provides integrated, collaborative capabilities for the full lifecycle, from requirements and logical design, through planning, change and configuration management, and test management. Featuring the new IBM Rational Engineering Lifecycle Manager (RELM), our solution offers specific support for aerospace and defense, automotive, medical devices, electronic design automation, energy and utilities, and telecommunications to help our clients meet their needs for compliance and rapid delivery. The solution can be further enhanced with tools and services from the extensive ecosystem of talented and experienced IBM Business Partners.
New or enhanced offerings fall into three areas of capability: product development lifecycle, industry solutions, and the partner ecosystem. The subsections that follow describe each of these areas.
The product development lifecycle
Enhancements for the product development lifecycle include these highlights:
- The new Rational Engineering Lifecycle Manager
- Rational Jazz™ technology-enabled improvements to Rational DOORS®
- Enhanced collaborative design capabilities through Rational Rhapsody® and Rhapsody Design Manager
- New practice guidelines integrated within the Rational Solution for Systems and Software Engineering.
Rational Engineering Lifecycle Manager
Rational Engineering Lifecycle Manager (RELM) 1.0 accesses data from a variety of Rational tools and can be extended to third-party and in-house tools. It includes support for indexing, accessing, and navigating to data from Rational Team Concert™, Rational DOORS, Rational Quality Manager, and Rational Rhapsody Design Manager (the last of which also gives RELM access to data from MathWorks Simulink).
RELM is extensible so that you can incorporate data from other sources. The data in the source tools needs to be exposed through web services that adhere to OSLC specifications. Incorporating that data into the RELM index requires knowledge of the Tracked Resource Set (TRS) specification. With RELM 1.0, IBM will work closely with clients to make data available to RELM from tools that they use from other vendors and from any tools developed in-house. This will most likely include tools supporting other engineering disciplines. IBM will be working with clients and business partners to extend the reach of RELM into third-party and in-house tools, too.
Jazz-based collaborative engineering
For the last few years, we have been introducing and improving OSLC-based integrations between DOORS and other tools. The latest OSLC support adds Rhapsody Design Manager integration with DOORS.
Rational DOORS Next Generation (DOORS NG, introduced in November 2012) offers requirements collaboration, planning, reuse, and lifecycle traceability, based on the Rational solution to Collaborative Lifecycle Management (CLM) applications, which are integrated by using Jazz technology. DOORS NG natively employs Jazz application frameworks so that DOORS users benefit from the common services of the Jazz Team Server, including common user administration, searching, commercial database support, single sign-on, work items, and more. DOORS NG does not replace the DOORS 9 series but will be developed in parallel. DOORS customers with active support and subscriptions will be entitled to use both DOORS 9 and Next Generation capabilities. Data can be exchanged both ways, between DOORS 9.4 (and later) and DOORS NG, and requirements can be linked across the two tools. You can download DOORS NG from Jazz.net, where you can also participate in discussions, see development plans, and report defects or request enhancements.
To build DOORS NG, we have extended the technology first delivered in Rational Requirements Composer to address the needs for requirements engineering in large-scale, complex projects by bringing forward key concepts from DOORS and improving on them. As a result, it's now possible to reuse requirement types across modules and reuse requirements in more than one module, using a fully functional web client in addition to the rich client.
Collaborative design management
Rhapsody 8.0 with Design Manager 4.0 greatly enhances your ability to address complexity in your systems engineering and embedded software development work. A completely reworked user experience highlights the release. Systems engineers, embedded software developers, AUTOSAR engineers, architects, and testers alike will find the new Rhapsody optimized with automatic tool configurations geared to their roles, as well as improved usability and context-related guidance to increase effectiveness and productivity.
Rhapsody and Rhapsody Design Manager offer collaborative engineering practices that enable teams to:
- Simplify design collaboration through Jazz-based model management.
- Unify requirements and design with a "single-source of truth," using OSLC.
- Streamline safety-critical design by using certification assistance.
- Automate compliance with the latest SysML, AUTOSAR, and UPDM standards.
An additional highlight in the fall product launch for systems is new and enhanced lifecycle metrics, process guidance, implementation templates, and tool mentors. Product engineering and development teams can specify, design, implement, and validate complex products and the software that powers them with an integrated set of tools, practices, and services.
New features help you:
- Achieve greater value from lifecycle traceability with guidance on new ways to view and query linked data.
- Improve cross lifecycle reporting with new tool mentors and templates for document generation.
- Respond faster to emerging issues with new lifecycle metrics.
