摘要：The research focuses on exploring the shared knowledge among the instructional multimedia design and development experts comprising of software designer, graphic designer, subject-matter expert and instructional designer. A critical need exists for a solid understanding of the factors that influence team decision making and performance in order to identify interventions that can affect the decision making process and improving performance. The knowledge shared by the team is categorized into three groups of multimedia design principles encompasses of basic principles, authoring principles and design principles. The shared knowledge from the team is extracted through the Modified Delphi Technique. The outcome of the research will be synthesized as the shared knowledge among the experts and the basis for developing the empirically-based design guideline of multimedia design principle. The research provides a window to some of the factors underlying team acquisition and performance of a complex skill. Hence it is valuable in diagnosing team performance successes and failures in multimedia design and development. With an understanding of team cognition, hence, training and designing interventions can target the cognitive underpinnings of team performance. The ability to assess team cognition and predict team performance has far reaching implications for evaluating progress in the design and development process of multimedia. Predominantly, understanding the cognition underlying team performance facilitates interventions (design, training, selection) to improve performance in instructional multimedia design production.
