This paper evaluates team SA in air combat simulations. Team composition (in terms of diversity in team members' experience) as a factor that could influence team SA is analyzed in a study of 16 military fighter pilots performing simulated air combat missions in teams of two. The study used different measures to assess team SA, including SAGAT, self-appraisal, appraisal of teammate's state, and teamwork behavior and communication. The analysis of intercorrelations between different measures of team SA shows that they are not fully overlapping. The results show high association between good SA and team interaction as measured by information sharing and feedback, support, and backup behavior. The results also suggest the potential negative impact of diversity in team members' experience on team SA and interaction processes. Finally, we reveal that teams that perform well are characterized by individuals with high SA related to own task, well-calibrated confidence level, and good team interaction. On the other hand, teams that perform well do not necessarily do better in estimating their self-SA and teammate's status.

PurposeThe paper seeks to improve the understanding of knowledge identification and management in product design by studying designers' cognition and behavior.Design/methodology/approachKnowledge management becomes an essential process in product design. However, most organizations and designers do not understand what knowledge should and can be managed. Little research is focused on studying the cognitive and social psychological factors within knowledge activities. This paper is mainly focused on knowledge issues in product design. This study focuses on the internal human activities and explores knowledge management research utilizing a human factors perspective.FindingsIn this paper knowledge in product design is defined; knowledge in product design is identified and classified based on design decision‐making processes. Furthermore, how to improve the knowledge management process in collaborative decision making is presented.Research limitations/implicationsThis study uses an experimental approach and hopefully the research can therefore be generalized to other situations.Practical implicationsThis study provides guidelines for information technology support for knowledge management in product design.Originality/valueKnowledge used in product design is identified and classified. The paper explores knowledge management research by analyzing human activity, in combination with the study of management and engineering technologies.

The usability of the software system for capturing picture is important factor for the mobile phone's interface design, which will partly determine customers' appreciation of the value of the service. Review from a human factors perspective, there are various methods for evaluating usability However, there are no definite criteria for testing the usability of mobile phone camera software systems. This study presents a new framework for usability testing based on a typical human information processing. Usability is classified into four dimensions for testing: perception, learning/memorization, control/action and evaluative feeling. Furthermore, the criteria for testing the four dimensions of usability are defined for mobile phone camera software systems. Three different camera mobile phones are studied and compared based on task analysis and evaluation of the criteria proposed for usability testing in this study. The usability problems of three mobile phone camera software systems are identified. Suggestions for usability improvement are presented.
