The human factors aspects of a computer-based information storage and retrieval system were evaluated in three government intelligence services using questionnaire and interview techniques. It was found that many factors entered into satisfaction with the information system, including familiarity, ease of use, and importance. Other relevant factors included training in the use of the system, amount and type of information to meet needs in the system, and tolerances of individuals for irrelevant material in the output of searches. The interaction of these factors is discussed in relation to satisfaction with the system. © 1968, Human Factors and Ergonomics Society. All rights reserved.
