Models play an important role in systems analysis and design (SAD). A diagrammatic model is defined as a mapping from a domain to a visual representation in such a way that relevant information is preserved to meet a specific goal. So far, cognitive research on diagram criteria in relation to task performance has been fragmented. The aim of this paper is to (1) consolidate research on the cognitive processing steps involved during understanding and task performance with diagrams, (2) consolidate corresponding criteria for such diagrams to best support cognitive processing, and (3) demonstrate the support effective diagrams provide for performing SAD tasks. Addressing the first aim, we develop a theoretical cognitive framework of task performance with diagrams called CogniDia. It integrates different cognitive theories from research on diagrams in software engineering and information systems. Regarding the second aim, we review the literature to organize criteria for effective cognitive processing of diagrams. We identify research gaps on verbal and task processing. Regarding the third aim, we use the theoretical cognitive framework to investigate how diagrams support the SAD process effectively.

系统分析和设计中的认知图理解和任务绩效

模型在系统分析和设计 (SAD) 中发挥着重要作用。图表模型被定义为从域到可视化表示的映射，以保留相关信息以满足特定目标的方式。到目前为止，关于与任务绩效相关的图表标准的认知研究是零散的。本文的目的是 (1) 用图表巩固对理解和任务执行过程中涉及的认知处理步骤的研究，(2) 巩固此类图表的相应标准以最好地支持认知处理，以及 (3) 证明支持有效的图表提供执行 SAD 任务。针对第一个目标，我们使用称为 CogniDia 的图表开发了任务绩效的理论认知框架。它整合了来自软件工程和信息系统中图表研究的不同认知理论。关于第二个目标，我们回顾文献以组织图表的有效认知处理的标准。我们确定了口头和任务处理方面的研究差距。关于第三个目标，我们使用理论认知框架来研究图表如何有效地支持 SAD 过程。
