- About This Item.
It is a historiography of task analysis, and the people who invented task analysis. It is also an explanatory primer on what cognitive task analysis is all about and what it can do. Perspectives on Cognitive Task Analyis will be of value to professionals in allied disciplines who might come to rely on cognitive task analysis in their system development programs.
It will be invaluable to students who need to know what task analysis and cognitive task analysis are really all about. Initial CTA artifacts such as semantic maps, functional models, decision requirements are inadequate for software developers. Given these artifacts form the underlying specification for system development, they are the critical targets if CTA is to effectively impact design.
Perspectives on Cognitive Task Analysis : Historical Origins and Modern Communities of Practice
This is important from several dimensions. First, to separate the information from the presentation in order to isolate the source of the problem in an ineffective design. Second, given the inevitable tradeoffs within implementation, to identify the critical aspects of the design concepts. Scenarios become a critical part of system development e.
Criteria to consider in developing and evaluating a CTA process should include:. Does it help generate new aiding concepts and innovations? Does the CTA help to identify the bounds of aiding? Does it help avoid typical design errors? Does it generate ideas that can be readily converted to system requirements to guide system design and testing?
Does it support distributed communication and coordination of design team members within and across organizational boundaries? Do the products of the CTA make contact with artifacts utilized in the software design process and can the results of the CTA be integrated into the software and product development process? Does it help address the envisioned world problem;. The criteria presented above help elucidate the requirements for software tools to support the CTA process.
The major benefits of applying software technology to the CTA process will not come from improving the efficiency of use of any given CTA technique. The real value of applying software technology comes from providing tools to support the modeling and documentation activities that are the products of the CTA that feed into the system development process. Our vision is to develop software tools that aid the CTA analysts in the modeling and documentation aspects of the CTA process to yield a more useful product that makes direct contact with the software development process and supports communication and coordination of CTA results among design team members distributed within and across development organizations.
We envision a tool that:. In this way it would support cognitive task analysts in capturing and maintaining the essential cognitive issues and relationships developed through a CTA yet will also be a tool for software developers to maintain awareness of the "design basis" underlying the resulting system requirements and specifications by forming a maintainable, traceable component of the functional design. The primary benefit of an integrated, tool-supported process will be the radical advance in the impact of CTA results on the resulting decision support system design.
