Are you an engineer? A systems designer or manager? A portfolio planner or an architect?

If so, you've come to the right place. Perhaps you're developing a new system that includes mechanical, electrical, and software components. Or maybe you're focused on the design and delivery of a software system to automate a business process. Today's engineering teams -- whether they specialize in electrical, chemical, mechanical, software, or other technical fields -- need, more than ever, to manage requirements, changes, versions, testing, and many other tasks in the project lifecycle. You need the best products that you can find for automating these management tasks and for delivering results that put you ahead of your competition.

These pages are designed to put you on the fast track to efficient project management, improved return on assets and investments, and successful project delivery. Your success is the primary focus of IBM Rational software.

About IBM Rational

As one of the five brands within IBM Software Group, Rational provides products, services, and guidance for software and systems development and delivery. Covering the entire project lifecycle from design to deployment, IBM Rational offerings concentrate decades of experience and know-how to help teams collaborate more effectively. Over the years, we have worked to create a complete and fully integrated set of products that increase productivity, decrease time to market, reduce costs and risk, and drive innovation that improves your competitive advantage.

IBM Rational provides a rich set of capabilities delivered as part of a collaborative and integrated range of products. Rational software is powered by Jazz technology and supported by proven best practice processes and an entire ecosystem of IBM and partner capabilities. Our integrated tools allow practitioners to operate more efficiently to deliver innovative products and services that differentiate business performance in both good times and bad.

By controlling the process of software and systems development in an open, flexible, proven and yet modular manner, software and systems development teams can:

  • Maximize return on investments and assets by automating and enforcing best practices that increase efficiency and improve predictably and reliability
  • Develop flexibly with an open, collaborative environment that unifies teams so that you can respond quickly to changing business priorities
  • Reduce costs and risk by effectively connecting distributed teams and providing secure and controlled access to shared resources, as well as help to ensure that projects are on time, on budget, and within scope

Regardless of your engineering environment or application type - Jazz, Eclipse, Java™, Microsoft® .NET, Linux®, or embedded and pervasive systems - Rational takes you from start to finish.

IBM Rational software and systems delivery practices help you define, automate, and integrate the key aspects of software and systems delivery across roles, from the analyst to the architect, developer, tester, and project manager. IBM Rational solutions are proven, complete, open, and modular.

  • Proven. We offer not just tools but a customizable framework that emphasizes best practices and processes that make thousands of high-performance software teams and practitioners successful.
  • Complete. You will gain confidence in your software and systems delivery lifecycle by supporting every member of your development team, as well as your business and operations stakeholders.
  • Open. You can leverage existing assets and choose from a wide array of development languages, deployment platforms, and partner technologies, including solutions that run on the Jazz platform (more about Jazz follows). Jazz technology transforms software development by making it more collaborative, productive, and transparent through integration of information and tasks across the phases of the software lifecycle.
  • Modular. You can choose the products and adoption path that best fit your needs and use your existing tools with components of the full IBM Rational portfolio. There is no need to "rip and replace" the tools and techniques you already have in place.

What Rational can do for you and your company

Most vendors who offer development solutions fail to address the entire software delivery lifecycle. Instead, they focus only on those areas where they have expertise. But with businesses under pressure to transform their investments for greater business value and use their investments as cost-effective enablers of innovation and success, every area of the lifecycle represents an opportunity for improving your team's effectiveness, predictability, and productivity.

The IBM Rational business-driven development approach addresses each phase in the software and systems delivery lifecycle. This results-oriented focus helps teams manage value, develop flexibly, and control risk and change. With the IBM Rational Software Delivery Platform, as well as a host of products specifically built for systems design and development, you get tools and best practices that help your team be successful. Key roles in the software and systems delivery lifecycle gain these substantial benefits:

  • Project managers: Improve the success and predictability of projects by being able to respond quickly to change, reduce delays and mistakes with real-time collaboration, and guide teams on best-practice processes for increased consistency and predictability. Easily view real-time information across projects, products, and locations to help measure, monitor, analyze, and project trends, and process performance.
  • Architects: Visualize, analyze, capture, and communicate business process design and system requirements and then help translate them into executable code to develop software faster.
  • Developers: Get immediate access to assets virtually anywhere in your organization with transparent, real-time availability of files and directories. Connect remotely when you need to so that you can remote work from any location. Automate tedious tasks, defect detection, and best practices guidance to improve efficiency, quality, and ensure consistent techniques and processes.
  • Entire team: Collaborate and automate across the entire project lifecycle to help streamline software and systems development and delivery.

As the diagram that follows shows, Rational capabilities address the needs of system engineers and software engineers alike, whether they're working to transform their company's IT organization or building a smarter product that will outshine the competition.

Rational offers modular, solution-focused products and services, as well as integrated product suites across the entire project lifecycle. Both products and services help teams address a wide array of today's challenges, including globally distributed organizations, regulatory compliance mandates, and the adoption of service-oriented development approaches.

Rational software ranks #1 among developers

In June 2009, IBM Rational tools were ranked #1 in Evans Data Corporation's 2009 User's Choice survey of developers' satisfaction. In their report, Evans Data said:

"This is no set of disparate tools thrown together in an attempt to bridge the problems of developers as they move from design to coding to deployment. Rather, the Rational tools suite, integrated together in the Jazz platform, takes software development into a new realm which blends together requirements, asset management, architecture, development, QA, deployment, and further to touch on operations and maintenance."
