In this study, we propose that perceived website complexity (PWC) is central to understanding how sophisticated features of a website (such as animation, audio, video, and rollover effects) affect a visitor's experience at the site. Although previous research suggests that several elements of perceived complexity (e.g., amount of text, animation, graphics, range and consistency of webpages configuring a website, ease of navigating through it, and clarity of hyperlinks) affect important user outcomes, conflicting results yielded by previous research have created an important debate: Does complexity enhance or inhibit user experience at a website? In this study, we draw on the task complexity literature to develop a broad and holistic model that examines the antecedents and consequences of PWC. Our results provide two important insights into the relationship between PWC and user outcomes. First, the positive relationship between objective complexity and PWC was moderated by user familiarity. Second, online task goals (goal-directed search and experiential browsing) moderated the relationship between PWC and user satisfaction. Specifically, the relationship between PWC and user satisfaction was negative for goal-directed users and inverted-U for experiential users. The implications of this finding for the practice of website design are discussed.
This paper utilizes a qualitative methodology, revealed causal mapping (RCM), to investigate the phenomenon of software operations support expertise. Software operations support is a large portion of the IS work performed in organizations. While we as researchers have access to generalized theories and frameworks of expertise, very little is known about expertise in this critical area. To understand software operations support expertise, a mid-range theory is evoked from interviews with experts and the construction of RCMs from those interviews. The results of this study indicate that software operation support expertise is comprised of five major constructs: personal competencies, environmental factors, support personnel motivation, IS policies, and support personnel outcomes. Additionally, this study revealed that these constructs interact differently in contexts where software support is the main activity versus contexts where the focus is development. This study demonstrates that the use of the RCM methodology yields constructs of software operations support expertise that are not suggested by generalized theory. In addition, the use of RCM as an evocative, qualitative methodology reveals the interaction and linkages between these constructs. This paper also provides a history of and tutorial to the RCM methodology for use by the research community.
