Business challenge story

Seizing a commercial opportunity

Imran Hashmi Canadian Hub for Requirements Management

The success of touchscreen interfaces on smartphones has led to increasing numbers of other devices adopting touchscreen technology—including laptops, cash registers, ATMs and even cars. Observing consumers’ keen appetite for touchscreens, and the greater usability they afford, Fagor Industrial set out to capitalize on this trend by launching an industrial washer extractor that can be controlled via a touchscreen interface.

At the time, no similar offerings were available on the market, but the clock was ticking. Fagor Industrial knew that first-mover advantage would be critical in this new product segment. To seize the narrow window of opportunity, the company needed to design, test and launch its new touchscreen offering as quickly as possible.

“With Rational, we can design and launch new products faster than ever, sharpening our competitive edge.”

— Imanol Lukas Etxarri, Electronic Engineer, Research and Development, Fagor Industrial

Transformation story

Calling in the experts

Developing a first-of-its-kind product using the latest technologies is always a challenge. For assistance in the venture, Fagor Industrial engaged an expert team from ULMA Embedded, an IBM Business Partner. The ULMA team proposed adopting IBM Rational Rhapsody Designer for Systems Engineers to help accelerate the pace and improve the quality of development.

Imanol Lukas Etxarri, an Electronic Engineer in the Research and Development Department at Fagor Industrial, explains: “We have worked with ULMA Embedded Solutions many times in the past, and they are one of our key strategic partners. When we decided to develop a new touchscreen washer extractor, we knew that it would be difficult, so we engaged ULMA Embedded Solutions to help us on the journey.

“We have a very strong relationship with ULMA because their engineers have an in-depth knowledge of the latest market trends, best practices and cutting-edge development tools. When they advocated Rational Rhapsody for this particular development, we were quickly convinced that it was the right recommendation.”

Results story

Achieving a clean sweep

Previously, Fagor Industrial built new embedded systems by first manufacturing the hardware, then developing the software using the C programming language, running on microcontrollers. Although most of the company’s previous products had fewer functions and a simpler interface than the new touchscreen washer extractor, the programming was complex and time-consuming.

In addition, the traditional development process required significant investment in building a physical prototype before the company could obtain feedback on the product from marketing and other departments, and then finalize the design.

With Rational, all that has changed, as Imanol Lukas Etxarri explains: “Rational offers a broad array of advantages in developing a new product. For example, it allowed ULMA Embedded Solutions to begin by designing all of the hardware on the computer, and simulate the results.

“This meant we could show detailed simulations of the new product to our customers, marketing personnel and executives to obtain their feedback. We worked with them to get the look, feel, functionality and usability of the new product right before we built physical prototypes—resulting in major time and cost savings.”

Additionally, the flexibility of the Rational solution made it easy for ULMA Embedded Solutions to develop new functions requested by Fagor Industrial—such as personalized washing cycles—and incorporate them into the new washer extractor’s control panel and processes.

As the development team made changes to the definitions of the washing cycles, the Rational software automatically updated any dependent processes—for example, telling the drum when to spin, empty or fill with water. Thanks to this automation, ULMA Embedded Solutions was able to develop the hardware for the new washer extractor 25 percent faster than expected.

Imanol Lukas Etxarri continues: “Thanks to ULMA Embedded Solutions and Rational software, we were able to cut time-to-market by up to 30 percent. Because we launched our touchscreen washer extractor before our competitors brought their products onto the market, we gained first-mover advantage. Our offering has been a hit with customers because it offers a user-friendly touchscreen and helpful features for personalized wash cycles.”

He adds: “With any innovative product, you can expect to encounter some service and support issues immediately after the launch. However, with our touchscreen washer extractor, we experienced far fewer issues than expected. Because we identified and solved many potential problems in the simulation stage, we have been able to achieve a higher standard in the end product.”

In the future, Fagor Industrial plans to enhance its touchscreen washer extractor with internet connectivity, tapping into the trend towards smarter laundries. As a result, customers will be able to control the devices remotely.

Building on its success, Fagor Industrial also plans to streamline the design of future products using Rational, enabling it to respond rapidly to emerging customer demands and hot trends in the market.

Benefits of using the kit

TÜV SÜD certificates to support tool qualification

The TÜV SÜD Certificate and Report to the Certificate provide an independent third-party review of the Rational DOORS development processes, customer support and defect processes, internal validation test suites, and the Rational DOORS Safety Manual. An organization can use the certificate and report to provide justification and evidence to qualify to use specific tools. The next table contains information about how the certificate and report can support tool qualification.

ISO tool qualification methodApplicability of the TÜV SÜD certificate and related assets
1a: Increased confidence from use in accordance with 11.4.7The TÜV SÜD evaluated the customer information and bug tracking of IBM Rational software, which contributes to an increased confidence because it helps with systematically collecting data and acquiring errors over a large number of customers and projects. This is only one part of the argument and needs to be extended by you based on your usage of Rational DOORS.
1b: Evaluation of the tool development process in accordance with 11.4.8The TÜV SÜD evaluated the Rational DOORS development process according to an appropriate standard based on the relevant portions of the ISO 26262:2011 standard. In addition, IBM holds an ISO 9001 certificate for the Rational DOORS development process. Therefore, the TÜV SÜD certificate and the ISO 9001 certification can be used as justification for this tool qualification method.
1c: Validation of the software tool in accordance with 11.4.9The TÜV SÜD analyzed the validation suite that IBM uses for Rational DOORS relative to the usage of features that are described in the Rational DOORS Safety Manual. Each organization must ensure that the described conditions of use and the used features match the descriptions in the safety manual. Any features that are not described in the safety manual are not covered by the certificate and need extra measures, such as manual validation.

In addition, IBM provides a Rational DOORS Intended Use Validation Test Suite for customers who want to use Rational DOORS differently than is described in the safety manual to validate that the features work as intended in their environment. This test suite is not covered by the certificate, but the test suite can be used to help enforce the argument for 1c.
1d: Development in accordance with a safety standardThis argument is not applicable because Rational DOORS was not developed as a safety item in accordance with a safety standard. The methods that the ISO 26262 requires, such as MC/DC coverage and semiformal verification, are not completely applied.

Validation test suite to run validation tests in specific environments

The Rational DOORS Intended Use Validation Test Suite is a customizable Rational DOORS project that contains a set of requirements that trace to features, test cases, and tests. You can run the tests in your environment to document and verify your usage of Rational DOORS.

Rational DOORS ISO 26262 template

The ISO 26262 template includes the basic modules and attributes that you can use to capture requirements and safety information throughout the safety lifecycle. The template also includes DXL scripts that determine the Automotive Safety Integrity Level (ASIL) of a safety goal based on severity, exposure, controllability, and the propagation of the ASIL down the requirements hierarchy from the safety goals.

Additional resources
