ABSTRACT

Ergonomics brings the human focus to systems engineering. As an engineering discipline, ergonomics integrates with other engineering disciplines to provide a complete systems approach to the design, development, and evaluation of a given product. Human Factors Integration (HFI), known as Human Systems Integration (HSI) in the United States, broadens ergonomics and focuses on the analyses and tradeoffs among the various HFI domains. According to MOD (2005), HFI is a systematic process for identifying, tracking and resolving human related issues ensuring a balanced development of both technological and human aspects of capability. Bruseberg (2008) states that HFI is an integral component of systems engineering, both of which, must be accomplished together to ensure system success. Systems engineers use architecture frameworks to describe complex systems. An architecture is the structure of components, their relationships, and the principles

and guidelines governing their design and evolution over time (IEEE STD 610.12, 1995). An architecture framework defines a common approach for development, pre-

sentation, and integration of architecture descriptions. It provides the guidance and rules for developing, representing, and understanding architectures based on a common set of products and product descriptions. The application of a framework enables systems engineers and HFI analysts to contribute more effectively to building interoperable systems. Architecture frameworks provide a mechanism for understanding and managing complexity. As currently described frameworks fail to capture the human-centered design aspects necessary to ensure the effectiveness of human operated and maintained systems. The objective of this current analysis was to explore the dynamic aspects of the Human View as an effective methodology for HFI practitioners coordinating and collaborating with systems engineers. Data from a system development effort was used to build various Human Views. Modeling and simulation were used to analyze the dynamic operator elements of the system and to augment the Human View process.
