Summary
In Patricia Sullivan’s article, “Beyond a Narrow Conception of Usability Testing,” she began by discussing the need for a broader interpretation of usability because of its complex nature. Next, she asks “what is it that we are doing in relation to others who study usability, and what might we need to be doing?” First, she notes that technical writers should contribute to research regarding the broader concept of usability. Because a broader interpretation of usability also means a larger body of information to tackle, studies should be situated within the umbrella of usability research, but both the context of a study and the study in and of itself should be analyzed as well. Analyzing the context of a study allows researchers to understand the choices made within the study, such as the chosen population. Analyzing the structure of the study allows researchers to understand factors such a study’s focus and constrains. However, depending on the identity of the group that conducts the study, such as sociologists or psychologists, different questions may be raised. For example, in the interdisciplinary group of human-computer interaction, all researchers are concerned with interface design, but may approach it differently by employing various methods and asking differing questions. Sociologists focus their studies on usability and how people interact with computers via observational techniques, while marketers focus their usability research on specific products and services. Technical communicators focus their research on the educational documents regarding a system and “how users employ those aids to help them learn a system.” The research of technical communicators is often interdisciplinary, so research methods are consulted as guides, rather than as set rules of practice. Researchers can then employ any combination of methods that they see fit in their research. Some research methods for usability studies include surveying, observation, keystroke records, and computer text analysis. The various methods can be organized into three models of research. First, the product development model pertains to the product development process of engineering, so it utilizes lab-based research methods. The cognitive model is based on the work of human-computer interaction psychologists, whose focus is on finished, developed products. The cultural model, often used by sociologists, utilizes field work in order to study “normal use” usability. Each model is also related to certain types of questions. For example, the cultural model is often connected to questions regarding the environment, or context, of a study. In closing, Sullivan addresses three questions pertaining to usability research. First, she argues that usability research can “develop methods for enhancing product development,” particularly if usability is tested earlier in the product development process. Second, she claims that she is unsure of whether or not usability research can be used as a “model” for studying “naturally occurring” usability until more field research is conducted on the subject. In closing, Sullivan enthusiastically argues that usability could become more “central” to the writing process in general due to advances in usability research. When technical communicators are aware of users and when usability research is implemented at the front-end of the writing cycle, technical communicators are able to produce significantly more effective and usable documents.
