In a concerted effort to enhance operational efficiency, safety, and workforce diversity, Rockwell Automation has intensified its focus on inclusive design principles across its vast portfolio of industrial automation solutions. This strategic imperative, detailed in an ongoing series of insights, underscores a fundamental shift in how complex industrial hardware and software are conceptualized, developed, and deployed, moving beyond traditional design paradigms to embrace the needs of a wider spectrum of users. The initiative reflects a growing industry recognition that inclusive design is not merely a compliance issue but a critical driver of innovation, market leadership, and sustainable growth in an increasingly global and diverse industrial landscape.
The Imperative for Inclusive Design in Industrial Settings
The industrial automation sector, characterized by its reliance on robust equipment operating in often demanding and unpredictable environments, faces unique challenges in implementing inclusive design. Unlike consumer electronics, industrial solutions must function flawlessly under rigorous conditions, often for decades, supporting a workforce that is becoming more diverse in age, physical ability, and background. This evolution necessitates a proactive approach to design that anticipates varied human factors, ensuring that every piece of equipment and software interface is accessible, intuitive, and efficient for all operators.
Industry analysts highlight that an aging workforce, coupled with a global talent pool that brings diverse physical and cognitive profiles, makes inclusive design an economic and operational necessity. Reports from organizations like the World Economic Forum consistently point to the importance of inclusive workplaces for productivity and innovation. Companies that fail to adapt risk not only alienating a significant portion of their potential workforce but also incurring higher training costs, increased error rates, and diminished safety outcomes. Rockwell Automation’s commitment, articulated through a multi-part series, illustrates a comprehensive strategy to embed inclusive principles deeply within its product development lifecycle, addressing both tangible hardware and the intangible aspects of language and user experience.
Hardware Design: Engineering for Diverse Operators in Rugged Environments
A cornerstone of Rockwell Automation’s inclusive design philosophy lies in its approach to hardware development. Industrial equipment is inherently exposed to extreme conditions, from cramped machine interiors to dimly lit factory floors, making physical accessibility and clear information display paramount. Alex Mummert, Senior Industrial Designer at Rockwell Automation, emphasizes the critical need for hardware solutions that accommodate diverse human beings, including those with disabilities, without compromising performance or reliability.
Mummert elaborates on several key considerations driving their hardware design strategy. Location plays a significant role, with products needing to be accessible whether mounted on a machine or within a cabinet. The challenge lies in standardizing information display and access across varied configurations, minimizing obstructions, and maximizing legible viewing angles – both vertical and horizontal. This ensures that critical data is discernible regardless of an operator’s height or position relative to the equipment.
Ergonomics are another vital aspect, with Mummert stressing the ambition to "design for the 99th percentile." This means standardizing grip points, pull forces, and space affordance to accommodate nearly the entire population without significant impediments. The process involves rigorous low-fidelity ergonomic validations, such as evaluating the door-opening feature of an I/O module in proximity to cables (as depicted in Figure 1 of the original series). This proactive testing, akin to software usability studies, ensures that physical interactions are comfortable and efficient for a broad range of users, including those wearing protective gear like gloves, which can reduce dexterity and tactile feedback.
The physical characteristics of industrial environments – often cramped, poorly lit, and dirty – directly influence design choices. Mummert explains that products are designed with these variables in mind to minimize their impact. This includes adjusting cabling directions and maximizing interface legibility. A clear hierarchy for information, whether static labels or dynamic light indicators, is essential for quick comprehension in stressful or low-visibility situations.
Regarding indicators and lights, Rockwell Automation has implemented updated wavelength guidance to ensure proper, inclusive color affordance for users with vision impairments. Historically, overlapping color specifications for green and yellow LEDs could cause confusion, a critical issue when conveying automation device statuses. By using blue-green and yellow-green indicators, and increasing the physical spacing between LEDs, the design team ensures that individual indicators are discernible, even in poor visibility or for those with color vision deficiencies. This deliberate spacing helps users identify "the third indicator is flashing" rather than perceiving a single, continuous color, which is crucial for rapid problem identification in high-stakes industrial settings.
Finally, user-interface responsiveness in hardware is designed to provide distinct and consistent feedback. Whether it’s the tactile click of a locking mechanism on a Programmable Logic Controller (PLC) or the visual confirmation of an action, feedback must be unambiguous. This is particularly important for operators wearing gloves, where haptic feedback might be diminished. By testing solutions with protective gear in realistic environments, Rockwell Automation ensures that critical interactions are reliable and intuitive for all users throughout the product lifecycle, from unpacking and commissioning to maintenance and replacement.
Lexical Modernization: Fostering Inclusive Communication
Beyond hardware, Rockwell Automation recognizes that language itself forms a crucial component of inclusive design. The technology industry, including automation, has historically perpetuated noninclusive terminology that can alienate users and employees. Elena Dunne, Senior Manager of Industry Insights and a former terminologist, has spearheaded Rockwell’s initiative to modernize its terminology strategy, addressing both external software and internal communications.
The challenge is significant given the decades-long lifespan of many industrial software and hardware solutions, and customer reluctance to alter anything that might disrupt productivity. Nevertheless, Rockwell Automation has made substantial progress in adopting more inclusive language. Dunne recounts engaging with external parties like standards organizations, partners, and customers through the "TerminOrgs" consortium to identify and implement alternatives to noninclusive terms. This collaborative approach has fostered broader industry acceptance for changes.
To amplify this effort, Rockwell published a blog and a dedicated page on its website (Figure 2 in the original series) listing preferred alternatives across various subdomains, including cybersecurity, motion control, and software programming. This publicly accessible resource demonstrates transparency and commitment, and the list is continually evolving. The company has also actively promoted these changes at industry events, such as its annual Automation Fair® tradeshow, integrating inclusive terminology into "Bold Conversations" roundtable talks to drive dialogue and adoption.
Internally, proactive and transparent communication has been vital. Dunne highlights a multi-pronged approach involving newsletters, SharePoint sites, presentations, and interactive Q&A sessions to keep employees informed and engaged. A cross-functional working group, comprising five distinct workstreams, oversees the implementation: a Terminology Review Board, a Style Guide and Content Authoring workstream, a Communication and Training workstream, a Global Translations and Localization workstream, and a Product Development workstream. This structured approach ensures that inclusive terminology is not merely a directive but is systematically integrated into all aspects of product development and communication. The goal, as Dunne emphasizes, is to build these practices into the productization pipeline, preventing issues before they arise through the newly formed Inclusive Design and Accessibility function.
Software Accessibility: Building Foundations with Design Systems
The challenge of retroactively updating decades-old industrial software solutions that were not originally designed for accessibility is immense. Rockwell Automation’s strategy for forward-looking software accessibility centers on its internal Flourish Design System (Figure 3 in the original series), ensuring that all new releases undergo rigorous implementation and testing of accessibility best practices. Jonathon Gulbrandsen, Design System Leader at Rockwell, explains how Flourish is leveraged to drive the adoption of accessible, inclusive design patterns.
Prioritization was key, with an initial focus on achieving proper contrast ratios within common components, followed by keyboard accessibility. Gulbrandsen notes that keyboard accessibility was an "easy sell" to business leaders because its benefits extend beyond users with impairments to power users. In immersive, integrated design environments (IDEs) like Rockwell’s FactoryTalk® Design Studio, system designers and automation engineers often prefer keyboard navigation for its speed and efficiency, reducing the physical and cognitive load associated with continuous mouse use. This demonstrates how accessibility improvements often enhance usability for all users.
To ensure appropriate contrast ratios, the Design System team embedded a requirement into their component-design process to test and ensure compliance with at least AA WCAG 2.1 (Web Content Accessibility Guidelines) standards for graphics and UI components, striving for AAA standards for text. Compliance with modern web standards like WCAG is viewed by product leaders as a way to build customer and user confidence, meeting the needs of diversifying workforces and demonstrating responsible technology development.
This ongoing work includes expanding the accessibility section within the design system’s documentation for every component. Furthermore, Gulbrandsen reveals plans to make the design system themeable, allowing products to offer various visual presentations such as dark or high-contrast themes. Such flexibility will broaden audience reach and cater to individual preferences and environmental conditions, further cementing Rockwell’s commitment to inclusive design.
