SERVICESCOGNITIVE SYSTEMS ENGINEERING Product managers and systems engineers grapple constantly with the "human component" when designing new technology systems. There is a scarcity, however, of rigorous, formal, quantitative methods for designing human interaction with new technology early in the development lifecycle. As a result, HSI problems often are not identified until late in the engineering effort when changes are far more costly. At worst, design problems become permanent training problems. Aptima solves this challenge through cognitive systems engineering, a scientific approach to integrating new technology into complex sociotechnical systems Innovative techniques, proven science. Aptima develops and applies innovative engineering techniques to define and evaluate system requirements early in the development lifecycle. Once prototype systems are available for testing, we apply modeling and simulation to improve the quality and cost-effectiveness of field data collection. The overall goal is to identify critical points of potential performance failure and correct them as early as possible in the process. Aptima’s key advances in cognitive systems engineering include:
INTERACTION DESIGN & USABILITY ASSESSMENT Sociotechnical systems are by definition complex and information-rich. Traditional user interface (UI) design and evaluation methods don’t identify or solve the design challenges these systems present. Aptima believes that usability is best achieved by designing technology for people, rather than adapting people to technology. To achieve this, we use our unique Work-Centered Design A focus on user performance. Work-Centered Design focuses on the user’s performance within the total job environment, not just how the user interacts with technology. By developing a deep understanding of the tasks users need to perform, the information they require, and the features of their domain, Work-Centered Design produces ecological interfaces Part of a total solution. Aptima understands that UI design is only part of an integrated system. We recognize that total work design involves job design, workflow design, UI design, and team design. Aptima is unique in applying a cost-effective modeling approach to interface design, including models to simulate the user/operator, the task, and the information needed. This insures efficient interaction design – with fewer design iterations and less user testing – while producing a highly effective result.
