Input requirements vary according to type of analysis performed. Reports range from detailed task timelines, diagnostic reports of subfunction and tasks failures, and overall mission success reports. Other reports include detailed workload timelines and percent-time in a high workload condition. Still others include time spent in direct maintenance and overall system availability and readiness. The standardized questions concern task learning difficulty, learning decay rate, task frequency, percentage of time performing task, and time to train task.
Similar data is collected from other sources.
The high driver tasks are identified for the purpose of assuring that similar problem tasks do not recur on the new system. 221-1822 WinCrew WinCrew is the ideal tool for studying systems when a central issue is whether the humans will be able to handle the workload. It allows the system analyst to predict and assess changes in system performance as a result of varying function allocation, number of operators or crew, level of automation, task design, mode of information presentation, and response to high workload. Through iterative use, the analyst can determine high drivers affecting human and system performance. WinCrew is most useful before Milestone II, both for identifying feasible crewstation designs and for evaluating prototypes and mock-ups of proposed crewstation systems.
