“…In practice, most work on usability of DLs has involved classical empirical studies of single libraries or features within librariesgenerally conducted or commissioned by the systems' developers, to inform future developments (e.g. [19] [23]). While this work has advanced the general understanding of usability issues for DLs, it seemed to us that empirical work could usefully be complemented by analytical techniques : o While empirical studies tell you what people do, they often fail to highlight what it is about the design of the system that is provoking particular user behaviors.…”

There are two main kinds of approach to considering usability of any system: empirical and analytical. Empirical techniques involve testing systems with users, whereas analytical techniques involve usability personnel assessing systems using established theories and methods. We report here on a set of studies in which four different techniques were applied to various digital libraries, focusing on the strengths, limitations and scope of each approach. Two of the techniques, Heuristic Evaluation and Cognitive Walkthrough, were applied in text-book fashion, because there was no obvious way to contextualize them to the Digital Libraries (DL) domain. For the third, Claims Analysis, it was possible to develop a set of re-usable scenarios and personas that relate the approach specifically to DL development. The fourth technique, CASSM, relates explicitly to the DL domain by combining empirical data with an analytical approach. We have found that Heuristic Evaluation and Cognitive Walkthrough only address superficial aspects of interface design (but are good for that), whereas Claims Analysis and CASSM can help identify deeper conceptual difficulties (but demand greater skill of the analyst). However, none fit seamlessly with existing digital library development practices, highlighting an important area for further work to support improved usability.

“…Historically, much work on usability of DLs has been post hoc -at least in the sense that a fully functioning prototype system exists to be tested (e.g., Papadakis et al, 2002;Komlodi and Marchionini, 1998). More recently, there has been an interest in check-list based approaches that make explicit some of the desirable features of DLs (e.g., Kyrillidou and Giersch, 2005).…”

In recent years, there has been great interest in scenario-based design and other forms of user-centred design. However, there are many design processes that, often for good reason, remain technology-centred. We present a case study of introducing scenarios into two digital library development processes. This was found to disrupt established patterns of working and to bring together conflicting value systems. In particular, the human factors approach of identifying users and anticipating what they are likely to do with a system (and what problems they might encounter) did not sit well with a development culture in which the rapid generation and informal evaluation of possible solutions (that are technically feasible and compatible with stable system components) is the norm. We found that developers tended to think in terms of two kinds of user: one who was exploring the system with no particular goal in mind and one who knew as much as the developer; scenarios typically work with richer user descriptions that challenge that thinking. In addition, the development practice of breaking down the design problem into discrete functions to make it manageable does not fit well with a scenario-based approach to thinking about user behaviour and interactions. The compromise reached was scenario-informed design, whereby scenarios were generated to support reasoning about the use of selected functions within the system. These scenarios helped create productive common ground between perspectives.

One of the long-standing challenges in HCI has been the integration of usability evaluation methods within design practice. In the work reported here, we investigated the question of how to include user concerns within an unstructured, system-focused development process.The project investigated the use of Claims Analysis as a method for assessing the effects of design decisions on users' experience. Claims Analysis was found to be more difficult than expected to learn, to communicate to systems developers and to apply effectively in practice.The work has highlighted a tension between user-centred and function-oriented design approaches, and differences in values and perspectives between the human factors specialists and traditional developers involved in the study.
