System modeling and analysis is used to predict performance of both conceptual and actual designs as system implementation progresses. These studies are used to influence the final system architectures to ensure the operational flexibility needed to accomplish mission objectives. These personnel undergo a rigorous training program, testing, and performance evaluation under stressful flight like simulations. Everything that can be done is done to prepare these individuals for the demands of real time flight operations. The Payload Systems Group is responsible for the development of flight and ground procedures necessary for the operations of onboard systems.
Training is provided to individual payload developers and flight controllers.
The majority of procedures used onboard the ISS will be viewed by the crew in an electronic format. The Payload Systems Group has the responsibility to ensure operability of payload displays and procedures for onboard. It is critical that displays be designed in a task oriented fashion to enhance overall usability, speed crew training, speed onboard crew activities, and prevent introduction of inadvertent errors. The rigorous application of Human Computer Interface standards, operations analysis, and crew review are used to achieve these ends. Using the Internet, the DUET system is a combination of remote usability testing and wide area network communication tools for use by the Payload Systems Group engineers, display developers, and reviewers.
