Mobile information systems (IS) hold great promise to support organizational processes. Clear guidelines, however, of how to design effective mobile IS in support of organizational processes have not been developed. Based on earlier research that emphasizes the importance of fit between organizational tasks and technology and that develops fit profiles for specific task−technology combinations, this paper develops a task−technology fit (TTF) profile for mobile IS to support managerial tasks. We suggest a three−way match between dimensions of managerial tasks, mobile IS, and the mobile use context. We find that use situations characterized by high distraction and poor quality of network connection are particularly challenging for the design of mobile IS, and that the user interface requires particular attention. The proposed conceptual model of task−technology fit provides guidelines for the design of effective mobile IS and for future research studies.

As widely recognized in the literature, information technology (IT) investments have several special characteristics that make assessing their costs and benefits complicated. Here, we address the problem of evaluating a web content management system for both internal and external use. The investment is presently undergoing an evaluation process in a multinational company. We aim at making explicit the desired benefits and expected risks of the system investment. An evaluation hierarchy at general level is constructed. After this, a more detailed hierarchy is constructed to take into account the contextual issues. To catch the contextual issues key company representatives were interviewed. The investment alternatives are compared applying the principles of the Analytic Hierarchy Process (AHP). Due to the subjective and uncertain characteristics of the strategic IT investments a wide range of sensitivity analyses is performed. 1

Email has evolved as the most widely used information system in organisations. Many organisations are now dependent on the use of email to manage internal communication as well as other communication and business processes. With this emergence of the universal use of email have emerged some negative aspects of email usage which have a negative impact on personal and organisational productivity. It is now necessary to recognise these negative impacts of email so that structures may be put in place to minimise and control them and related impacts on productivity. In an approach to quantify the negative impact of email this paper identifies negative aspects of email usage and proposes a model which may be used to quantify each aspect and, in turn, quantify the impact of these aspects on productivity. This approach would allow the confirmation of negative issues of email usage and allow formulation of approaches for their management.

Social networking sites such as MySpace and Facebook thrive on energetic social interaction, but the factors that assure this are not well understood. There is a lack of theory that can describe and predict the successful adoption of new social computing systems. This paper introduces the Social Software Performance Model, and uses it to interpret the evolution and usage of social networking sites. Drawing from socio-technical systems theory, task technology fit, and structuration theory, this model identifies the components of social software, and describes their role in the evaluation and adoption of these systems. The results of three studies are presented, providing initial empirical evidence for the model.

Trust and privacy concern within social networking sites: A comparison of Facebook and MySpace

In today’s knowledge economy, technology is utilized more than ever to deliver instructional material to the learner. Nonetheless, information may not always be presented in a manner that maximizes the learning experience, resulting in a negative impact on learning outcomes. Drawing on the Task-Technology Fit model, a research framework was developed to investigate the influence of vividness, interactivity, task complexity, and learning style on performance, satisfaction, interest, and perceived mental effort in the context of learning how to use an office productivity tool via a computer-mediated learning environment. It was hypothesized that vividness and interactivity would increase satisfaction and interest and that the affects of vividness and interactivity on performance and perceived mental effort would vary depending on the complexity of the task. It was also hypothesized that vividness and learning style would interact to influence performance and perceived mental effort when a task was more complex. A laboratory experiment was employed to test the research model. The experiment manipulated two levels of vividness, interactivity, and task complexity, resulting in six unique treatment conditions. In each of these treatment conditions, subjects viewed a computerbased tutorial on how to complete a task using a specific tool in Microsoft Excel. Subjects were

There are Several Journals available in Computer Science field today, IJACSA is among the few with a belief of providing open access. Our Goal is to create a new forum for exchange of Information on all aspects of computer Science and its varied Applications. Each of the paper in this Inaugural Issue approaches a pervasive theme of Wisdom Sharing from a different angle. At IJACSA, we stand strong because we know that global challenges make way for new innovations, new ways and new talent. The Papers have been kept limited in number, with an aim to provide best-of breed Research Papers and Discussions. The Paper Acceptance Rate for this issue is 34.6%. But I know that amongst the readers there is a good deal of intellectual thinking in the area that our journal focuses on, I, therefore respectfully ask that you consider preparing a submission for our Journal. IJACSA has drawn the best of talent from Industries and Institutions across the globe to ensure that we retain high standards. We are very grateful to all the authors who

Process modeling has become an essential aspect of information systems (IS) practice. In line with the increased popularity, a plethora of process modeling techniques has been proposed over time. Yet, despite the proliferation of techniques, only a few have been widely accepted by practitioner communities. However, the long-term viability of a process modeling technique and its eventual success depend on its extensive and continued use by process modelers. While IS researchers have extensively studied the continued acceptance of information systems artifacts, to date, only little research exists that has investigated the issue of process modeling technique continuance. This paper addresses the problem of process modeling technique continuance by identifying from prior research factors that influence the formation of an intention to continue using a process modeling technique and by performing a theoretical integration of appropriate theories of post-adoption behavioral intention. The resulting research
