IEEE 845-1998 pdf download IEEE Guide for the Evaluation of Human-System Performance in Nuclear Power Generating Stations
For the purposes of this guide, the following terms and definitions apply. IEEE Std 100-1996 (B2] should bereferenced for terms not defined in this clause.
2.1 human-system interface (HSI): The interaction between workers and their equipment. This interactionrequires information to flow in two directions. The system provides status information to the user, and theuser provides control information to the system. (Used in other texts as man-machine interface (MMI,human-machine interface (HMl), human-machine system (HMS), and human-computer interface (HCI).](For further information see IEEE Std 1289-1998 B5])
2.2 system development cycle: The life cycle through which a system is developed, which consists of thefollowing:
a)Concept development;
6)Design;
9)Test and construction;
d)Operation;and
e)Maintenance (see IEEE Std 1023-1988[B3)
3. Evaluating human-system performance
3.1 General
To evaluate human-system performance, the evaluator needs to recognize that human performance is integrato system performance throughout design, development, testing, operation, and maintenance activitiesTherefore, human performance is an integral part of system performance evaluation. Human performance isinfluenced by many factors. For example, environmental conditions; organizational design; training; andphysiological, perceptual,and cognitive processes all infiuence human performance. The evaluator canapply various measures and evaluation techniques to formally evaluate the performance of people on tasks ofinterest.
There are several considerations that are associated with evaluating human-system performance. Theseinclude the following:
0Selection and implementation of the measure and technique
bAnalysis and interpretation of human performance data:
cMeasuring cognitive processes;
dGeneralizing from experimental studies; and
eEstablishing meaningful performance criteria for some tasks
A comprehensive approach to human-system performance evaluation will require attention to theseconsiderations. This guide includes brief discussions of selected considerations as they relate to theperformance evaluation techniques recommended here. For a more detailed discussion of potentiaconsiderations,see ANSI/AIAA G-035-1992[B11
This quide describes human-system performanceevaluation techniques that may be used to support thesystems design approach described in IEEE Std 1023-1988 (B3). These evaluation techniques include papeand pencil, observational,expert judgment, and experimental techniques. Human factors design analysestechniques (e.g., mission, function, task, and link analyses) are not included in this guide, but are described
