Abstract:
Information visualization supports human decision making, particularly in complex and highly cognitive situations. Implementing an inappropriate visualization creates confusion, distrust, and misuse for the human and the system. To identify the appropriate area to incorporate information visualization into a pre-existing system, the author proposes a task analysis method that incorporates doctrine and regulations with user jury results. To demonstrate the validity of this approach, the author conducted a case study with a maintenance manager in the United States Army (called the Battalion Maintenance Officer) in completing scheduled maintenance activities. Results indicate that the proposed methodology is effective in creating a robust task analysis and identifying candidate areas for visualization. This work can be expanded to other venues such as industry and service settings for an appropriate implementation of information visualization.
