The Cognitive Walkthrough methodology was developed in an effort to bring cognitive theory closer to practice; to enhance the design and evaluation of use interfaces in industrial settings. For the first time, small teams of professional developers have used this method to critique three complex software systems. In this paper we report evidence about how the methodology worked for these evaluations. We focus on five core issues: (1) task selection, coverage, and evaluation, (2) the process of doing a Cognitive Walkthrough, (3) requisite knowlege for the evaluators, (4) group walkthroughs, and (5) the interpretation of results. Our findings show that many variables can affect the success of the technique; we believe that if the Cognitive Walkthrough is ultimately to be successful in industrial settings, the method must be refined and augmented in a variety of ways.

evaluation; guidelines; usability testing; cognitive walkthrough A user interface (UI) for a software product was evaluated prior to its release by four groups, each applying a different technique: heuristic evaluation, software guidelines, cognitive walkthroughs, and usability testing. Heuristic evaluation by several ill specialists found the most serious problems with the least amount of effort, although they also reported a large number of low-priority problems. The relative advantages of all the techniques are discussed, and suggestions for improvements in the techniques are offered.

The value of theoretical analyses in user interface design has been hotly debated. All sides agree that it is difficult to apply current theoretical models within the constraints of real-world development projects. We attack this problem in the context of bringing the theoretical ideas within a model of exploratory learning [19] to bear on the evaluation of alternative interfaces for walk-up-and-use systems. We derived a “cognitive walkthrough” procedure for systematically evaluating features of an interface in the context of the theory. Four people independently applied this procedure to four alternative interfaces for which we have empirical usability data. Consideration of the walkthrough sheds light on the consistency with which such a procedure can be applied as well as the accuracy of the results.

On line data management techniques to certify spacecraft information are mandated by increasing telemetry rates [SiC87]. Knowledge-based expert systems offer the ability to certify data electronically without the need for time consuming human interaction. We have explored issues of automatic certification by designing a knowledge-based expert system to certify data from a scientific instrument, the Orbiter Ultraviolet Spectrometer (OUVS), on an operating NASA planetary spacecraft, Pioneer Venus (PV) [Ste80]. The resulting rule-based system, called PVDaCS (Pioneer Venus Data Certification System), is a functional prototype demonstrating the concepts of a larger system design. A key element of the system design is the representation of an expert's knowledge through the usage of well ordered sequences. PVDaCS produces a certification value derived from expert knowledge and an analysis of the instrument's operation. Results of system performance are presented.
