本文的动机是回顾层次任务分析（HTA）的地位，作为一个通用的框架，检查任务，包括那些认知任务分析方法可能被认为是必要的。HTA被视为检查任务的策略，旨在完善绩效标准，专注于构成技能，理解任务背景，并为克服绩效问题产生有用的假设。一个中立和有原则的观点避免了偏见，使分析师能够证明使用不同的分析方法是合理的，并在获得有关任务的信息时提出假设。有人认为，这些考虑是同样有效的，当检查任务，假设包含大量的认知元素。此外，在更广泛的任务背景下检查认知有助于将认知纳入它必须支持的行动和决策网络中，并有助于确定认知任务分析中的努力是否真正合理。
The motivation for this paper is to review the status of Hierarchical Task Analysis (HTA) as a general framework for examining tasks, including those for which cognitive task analysis methods might be assumed to be necessary. HTA is treated as a strategy for examining tasks, aimed at refining performance criteria, focusing on constituent skills, understanding task contexts and generating useful hypotheses for overcoming performance problems. A neutral and principled perspective avoids bias and enables the analyst to justify using different analytical methods and develop hypotheses as information is gained about the task. It is argued that these considerations are equally valid when examining tasks that are assumed to contain substantial cognitive elements. Moreover, examining cognition within the context of a broader task helps to situate cognition within the network of actions and decisions that it must support, as well as helping to establish where effort in cognitive task analysis is really justified.
