We describe how instant messaging supports a variety of informal communication tasks. We document the affordances of IM that support flexible, expressive communication. We describe some unexpected uses of IM that highlight aspects of communication which are not part of current media theorizing. They pertain to communicative processes people use to connect with each other and to manage communication, rather than to information exchange. We call these processes “outeraction.” We discuss how outeractional aspects of communication affect media choice and patterns of media use.

Young people have created and developed a communication culture that incorporates many special features, such as a rise in the use of text-based communication channels. Teenagers' intersecting and selective use of communication channels has generated multimedial communication. From the theoretical standpoint provided by symbolic interactionism, we can ask whether communication through new media technologies generates new forms of social interaction. If this is the case, how could we describe and analyse these new forms of interaction? The media landscapes created by teenagers serve to articulate their personal space, as well as enabling their presentation of self and defining their relationships to others. This article is based on thematic interview material, and its purpose is to analyse the meanings and use contexts of mobile communication and other multimedial communication culture among Finnish youth. 10.1177/1461444804042518 Mobile Communication as a Social Stage: Meanings of Mobile Communication in Everyday Life among Teenagers in Finland Virpi Oksman Jussi Turtiainen doi:10.1177/1461444804042518 New Media Society, Vol. 6, No. 3.

Simulation games can be used for promoting organizational development. They offer an arena for organization members to analyze the present state of an organization and create new organizational solutions. The bridge between the present and future mode of working can be built on by the ideas for improvement brought forward by the participants of the simulation game. The study focuses on the WORK FLOW GAME (WFG) (DIS). It integrates the following activities: work process improvement, use of information technology, and participation and learning by the personnel of a company or public agency. WFG promotes organizational innovations through interaction and cooperation of the people involved. The study showed improvements in the quality and efficiency of the work process, customer relations, and working conditions of the personnel. 10.1177/1046878103258203 Simulation Gaming for Organizational Development Virpi Ruohomaki doi:10.1177/1046878103258203 Simulation Gaming, Vol. 34, No. 4.

However, many professionals become confused when customers ask them to measure the usability of a software application, software program, web site, or other software product. In order to clarify the process of measuring usability, this tutorial first offers a definition of software usability metrics, gives examples of usability metrics, and reviews reasons for usability metrics. Next, the tutorial steps through the process of deciding what metrics and methods to use as well as when, where, and how to use them.

This paper describes a case study where the usability of an information system is improved and a relationship between the improvements and the evaluation efforts is established. Results show that evaluation techniques complemented each other by suggesting different kinds of usability improvement. Among the techniques applied, a combination of questionnaires and Metaphors of Human Thinking (MOT) showed the largest mean impact and MOT produced the largest number of impacts. Logging of real-life use of the system over 6 months indicated six aspects of improved usability, where significant differences among evaluation techniques were found. Concerning five of the six aspects Think Aloud evaluations and the above-mentioned combination of questionnaire and MOT performed equally well, and better than MOT. Based on the evaluations 40 redesign proposals were developed and 30 of these were implemented. Four of the implemented redesigns where considered especially important. These evolved with inspiration from multiple evaluations and were informed by stakeholders with different kinds of expertise. Our results suggest that practitioners should not rely on isolated evaluations. Instead complementing techniques should be combined, and people with different expertise should be involved.

In this paper, we define the quality attributes of eight major mobile data services used by mobile communication subscribers and measure customer expectation levels. Research progress follows QFD (quality function deployment). FGI (focused group interview) was used to define quality attributes and experiments, benchmarking and surveys were used to decide customers’ expectation levels.

First a review of the emerging discipline of geographic information retrieval (GIR) is presented as background to the more specific issue of mobile information retrieval. Following this, a user needs study is described evaluating the requirements of potential users of a mobile information system; the study finds that there is a strong geographic component to users' information needs. Next, four geographic post-query filters are described which attempt to represent the region of space associated with an individual's query made at some specific spatial location. These filters are spatial proximity (distance in space), temporal proximity (travel time), speed-heading prediction surfaces (likelihood of visiting locations) and visibility (locations that can be seen). Two of these filters spatial proximity and speed-heading prediction surfaces are implemented in a mobile information system and subsequently evaluated with users in an outdoor setting. The results of evaluation suggest that retrieved information to which post-query geographic filters have been applied is considered more relevant than unfiltered information, and that users find information sorted by spatial proximity to be more relevant than that sorted by a prediction surface of likely future locations. The paper closes with a discussion of the wider implications of these results for developers of mobile information systems and location-based services. 10.1177/0165551506075333 Geographic information retrieval in a mobile environment: evaluating the needs of mobile individuals David Mountain Andrew Macfarlane doi:10.1177/0165551506075333 Journal of Information Science, Vol. 33, No. 5.

(1 June 2005), pp. 123-134.</i><br /><br />This article seeks to highlight some distinctive issues involved in the use of mobile information and communication technologies (MICTs) in the healthcare context. A three-layered framework for analysing cases of MICT-in-use is developed from the literature and employed to analyse evidence from a number of healthcare MICT pilot studies. These indicate that MICTs create new implementation challenges, and that developers and implementers appear to pay little attention to the particular workflow modalities of mobility and their relationship with the type of MICT. In terms of effects on clinical work practices, MICTs seemed to make access to information easier but not necessarily faster. Better integration of MICTs with other hospital systems and use of wireless networks were seen as necessary to achieve greater uptake. Areas for further research that might support the implementation of MICTs in healthcare are identified. 10.1177/1460458205052361 What's so different about mobile information communication technologies (MICTs) for clinical work practices?

Field mobile computing has been at the forefront of police technology implementations throughout the United States for the past several years. This study measures how well these systems match tasks the field officers must perform and measures the effectiveness of field mobile computing as implemented in a medium-sized Southwestern police department. The authors found statistical support indicating that inquiries to local, state, and national criminal information databases increased with the implementation of mobile computing. The authors also found that field officers recognize the potential benefits mobile computing affords them and that the amount of time required for completing reports increased with the implementation of field mobile computing. Last, administrators, detectives, and records personnel all experienced statistically significant improvements in the tasks they performed, directly resulting from the implementation of mobile computing. 10.1177/1098611103251113 Police Field Mobile Computing: Applying the Theory of Task-Technology Fit Ralph Ioimo Jay Aronson doi:10.1177/1098611103251113 Police Quarterly, Vol. 7, No. 4.

Nevertheless, a quantified value of the usability could be used for several purposes, such as design innovation and benchmarking. This paper proposes three approaches (task centred, usability indicator-based, and design area-based quantification) to quantifying the usability of mobile phones on the basis of a hierarchical model of usability factors. Each of them provides process and rules for calculating the usability score of a mobile phone by applying weighting value assignment methods. Through two case studies, we could obtain empirical data to be used for determining the weighting value for quantification and confirm the usefulness of the proposed approaches.

Eighth World Congress on the (2007), pp. 10-10.</i><br /><br />Mobile work in an exposed physical working environment, e.g. the building industry, challenges the design and use of mobile services. So far, little or no use of mobile services on the building sites exists. This research presents mobile services that were developed and used in order to support knowledge processes in the building industry. The building workers used the mobile services to capture and report experiences and knowledge using pictures, audio records and textual information. It also presents experiences from using the mobile services as a part of a mobile knowledge management. The workers experienced that the mobile services could improve paper-driven knowledge processes on sites. Also, by using the mobile services the building workers contributed to improve the quality of work for the whole enterprise. This research also reveals unforeseen new use patterns that did not come in conflict with the existing knowledge processes.

First, this paper describes the aim, the concept based on end user computing (EUC), and the essential element of the mobile system. This also shows the necessary functions for the mobile computing, and the concept of this computer-aided engineering system. Secondly, this paper describes the structure of the system and the outline of subsystems: Inspection System, Checklist and Reference System, Position Check System, and Progress Monitoring System. The system has two programs: the data input program in PDA and the output program in PC. - Inspection System assists architects and construction managers to inspect the result of construction especially for finish works. - Checklist and Reference System assists construction managers to access the checklist and the reference such as drawings and specifications. - Position Check System assists construction managers to check and correct the position of structural members such as the steel column and the form. - Progress Monitoring System assists construction managers to monitor the progress of projects. Finally, this paper indicates the development of more refined process of construction management with the mobile computing device on construction sites.

Finding the right tradeoff between these two quality attributes is not an easy endeavor. In this paper, we introduce an original design model based on a novel usability inspection method. This new method, named Security Usability Symmetry (SUS), exploits automata machines theory and introduces the concept of an advanced Multifunction Teller Machine (MTM). We demonstrate, via case study, how to use this model during the design of secure, usable interactive systems.

Usability cost-benefit analysis models outline the potential benefits and costs of usability. This paper contrasts usability cost-benefit analysis literature with an empirical case in industrial setting, in which usability cost-benefit considerations (along with other usability activities) resulted in usability becoming a curse word. An interpretive case study was carried out in a SW development organization. Empirical analysis reveals that clearly divergent meanings and motives were attached to usability and its cost-benefit analysis in the organization. Increased sales and reduced development costs were strongly emphasized as benefits of better usability. However, very surprising meanings were attached to them both. Furthermore, the increased development costs associated with better usability were the main failure factor of the whole usability improvement effort. Implications both for theory and practice are discussed. Usability Cost-Benefit Analysis: How Usability Became a Curse Word?

By defining, analyzing, and redesigning an organization's resources and operations, workflow management systems ensure that the right information reaches the right person or computer application at the right time. The book provides a basic overview of workflow terminology and organization, as well as detailed coverage of workflow modeling with Petri nets. Because Petri nets make definitions easier to understand for nonexperts, they facilitate communication between designers and users. The book includes a chapter of case studies, review exercises, and a glossary.

In engagements where early user interface design mock-ups are needed to visualize proposed business processes, the need to quickly create UI becomes prominent very early in the process. Our work aims to speed up the UI design process, enabling rapid creation of low-fidelity UI design with traditional user-centered design thinking but different tooling concepts. This paper explains the approach and the rationale behind our model and tools. One key focal point is in leveraging business process models as a starting point of the UI design process. The other focal point is on using a model-driven approach with designer-centered tools to eliminate some design overheads, to help manage a large design space, and to cope with changes in requirements. We used examples from a real business engagement to derive and strengthen this work.

Unfortunately the design of multi-sensory displays is complex and it is necessary to carefully consider the perceptual capabilities of humans. Therefore we aim to both collect useful guidelines that help designers of multi-sensory displays and to structure these guidelines by using appropriate high-level principles. Gestalt principles suggest themselves as one possible framework for structuring multi-sensory design guidelines. Gestalt theory explains how humans organise individual elements into groups and how humans perceive and recognise patterns. Unfortunately very little work has been done in evaluating how well these principles apply to the haptic sense. This paper focuses on how individuals use the sense of haptic (touch) to group display elements using the gestalt principle of continuation. The hypothesis of the experiment is that people used their haptic perceptions to group display elements in the same way they group elements visually. Overall we find this hypothesis to be true and that a significant number of subjects group haptic elements so that they can be interpreted as continuous lines and forms. This supports our hypothesis that the gestalt principle of continuation is applicable for both visual and haptic grouping and therefore provides a useful principle for structuring multi-sensory design guidelines The Gestalt Principle of Continuation Applies to both the Haptic and Visual Grouping of Elements Dempsey Chang Keith Nesbitt Kevin Wilkins EuroHaptics Conference, 2007 and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.

Data were collected from a qualitative study and three different field studies of health care patients in two different health care contexts: oncology clinics and a general medical practice. Service quality was found to conform to the structure of the hierarchical model in all three samples. The research identified nine subdimensions driving four primary dimensions, which in turn were found to drive service quality perceptions. The primary dimensions were interpersonal quality, technical quality, environment quality, and administrative quality. The subdimensions were interaction, relationship, outcome, expertise, atmosphere, tangibles, timeliness, operation, and support. The findings also support the hypothesis that service quality has a significant impact on service satisfaction and behavioral intentions and that service quality mediates the relationship between the dimensions and intentions. 10.1177/1094670507309594 A Hierarchical Model of Health Service Quality: Scale Development and Investigation of an Integrated Model Tracey Dagger Jillian Sweeney Lester Johnson doi:10.1177/1094670507309594 Journal of Service Research, Vol. 10, No. 2.

Rapid development in mobile communication provides a great potential for us to move from traditional office support to mobile work support. Despite this great potential, we still lack the theory to fully understand the nature of mobile work. Without this understanding, it will be difficult to develop efficient and effective support for mobile workers. In this paper we propose a theoretical mobile work support framework and use this framework to analyze four fundamental aspects of mobile work: mobile workers, mobile tasks, mobile context, and mobile technology. The key differences between office work support and mobile work are also highlighted.

Various actors performing various roles have to collaborate in value networks to deliver those services. We formulated ten guidelines to support organisations creating these value networks. The backgrounds for these design guidelines are case study observations and literature studies from the fields of system engineering, process management and product design. The guidelines have been applied in an action research project in which a mobile information service was developed on a UMTS testbed and used by university campus visitors. The result of this test is that two guidelines were accepted without change and the others are adapted.

One reason for this is that the benefits of better usability are not visible for the management. In this paper, the characteristics of selected published usability cost-benefit models are analyzed. These models have different approaches for identifying, approaching and categorizing the costs and benefits of usability. The analyzed models provide general guidelines for estimating the costs and benefits of usability but in most cases provide only little details. It is proposed that the business type of development organization and the type of the developed product as variables could be taken into account when analyzing the benefits of better usability.

A number of research articles have been published in the literature on mobile commerce and wireless technologies, but very limited research has been reported on actual applications of m-business. The inadequate knowledge of managers and inexperience with mobile applications often characterized by third party opinions are among major factors inhibiting mbusiness development. In this paper we explore the opportunities for utilizing mobile technology in customer care operations, specifically focusing on crossboundary process improvement. Our argument is that business process redesign and changes in supporting infrastructure are necessary first steps to unsure successful transition of e-business applications that is to be potentially enhanced by the capabilities provided by mobile technology. Our paper contributes to this by presenting results of an exploratory single-case study. We document and explain a new customer care mechanism - mobile web-based system - piloted within fine paper supply chain of the case organization, one of the leading fine paper producers in Europe. Results demonstrate that both customers can benefit from it and that paper producing company will achieve significant performance improvements.

The majority of prev~ous IT productivity studies follow a technological imperative, hypothesizing a direct relationship between higher IT investments and increased productivity. This paper shifts the focus toward the organizational imperative, which views returns on IT investments as a result of the alignment between technology and other critical management choices. Specifically, the study focuses on the alignment between IT investments and worker composition, measured in terms of relative numbers of clerical, managerial, and professional positions to the total number of employees. Hypotheses are tested using a data set compiled over a 10-year period for 52 life insurance companies. With respect to prior research, the study is novel in its adoption of a model of productivity that accounts for both separate and combined effects of IT investments and worker composition. Premium income per employee and total operating expense to premium income are used as indicators of productivity. Study findings show that increases in IT expenses are associated with productivity benefits when accompanied by changes in worker composition. Life insurance companies that have decreased their proportion of clericals and professionals while af the same time investing in IT have experienced productivity improvements. On the other hand, companies decreasing their proportion of managers while investing in IT are found to have reduced productivity.

However, the source of these differences is unclear. In this study we analyze the role of the competitive environment in moderating the productive impact of information technology and regular capital. We focus on two important features of an industry's competitive environment: industry concentration and industry dynamism. Industry concentration is the degree to which the output of an entire industry is produced by a few firms and is considered an inverse proxy for industry competitiveness. Industry dynamism denotes change that is difficult to predict, measured as the deviation of industry sales from a trend line. We analyze the moderating impact of concentration and dynamism on the output elasticity of information technology and regular capital by estimating a production function using 5211 firm–year observations spanning the years 1987 to 1994. We find that the marginal product of IT is lower in more concentrated industries, while the opposite is true for regular capital. There is limited evidence that the marginal product of IT is higher in more dynamic industries, and strong evidence that the marginal product of regular capital is lower in more dynamic industries. Taken together, our results suggest that IT provides enhanced productivity impacts to firms in more competitive industries without any productivity loss in dynamic industries, in contrast to regular capital. The findings underscore the salience of inclusion of the competitive environment in studies of the productive impacts of information technology.

A review of the literature reveals that studies examining the association between information technology and organizational performance are divergent in how they conceptualize key constructs and their interrelationships. We develop a model of IT business value based in the resourcebased view of the firm that integrates the various strands of research into a single framework. We apply the integrative model to synthesize what is known about IT business value and guide future research by developing propositions and suggesting a research agenda. A principal finding is that IT is valuable, but the extent and dimensions are dependent upon internal and external factors, including complementary organizational resources of the firm and its trading partners, as well as the competitive and macro environment. Our analysis provides a blueprint to guide future research and facilitate knowledge accumulation and creation concerning the organizational performance impacts of information technology.

However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experienced in the filed of usability. Therefore, an integrated, accurate, consolidated and simple usability assessment model is required, to provide an entire construct of usability for general software products. In this paper, we proposed an Integrated Quantitative Assessment Model for Usability Engineering (IQAMUE) for measuring and reporting usability for general software products. The contribution of the IQAMUE has been done at several points: (1) The investigation into existing models that represents usability factors, either by standard bodies or by well-known researches in the field of usability. As a result, we have proposed an improved comprehensive model, which integrates potential and general usability factors, and measure their related metrics in a standard way (2) We have proposed an adjustable sample size estimation model for usability assessment, which enhances the estimation process, by using historical data to gain an initial idea of the software product, and on present data to predict the complexity of the software product (3) For the applicability purpose of the proposed model, we have conducted an empirical case study for a local e-mail system (Eudora V7) to examine and practice the proposed model.

Despite this knowledge, however, many mobile applications are designed as if they were merely shrunken desktop or Web applications. To encourage consideration of the specifics of context for mobile interactions and to highlight new user-meaningful opportunities latent in always-on, always-carried devices, this article describes a context model for mobile interaction and a set of design heuristics for successful mobile interactions.

Concerns have been raised whether agile methods are suitable for any given information systems development domain. Indeed, quite little is known empirically about the validity of agile methods in most of the industrial domains. Mobile information systems present no exception in this sense. Yet, they are subject to frequent requirements changes in terms of changing business needs and technology, and their market is highly competitive. Moreover, most of these systems are far away from so called agile home ground. This talk presents the need for agile methods in the focal domain, identifies their shortcomings on the basis of three large-scale case studies from industry. All of the cases deal with the development of mobile information system and come from Nokia, F-Secure and Philips. The talk also discusses the possible strategies for deploying agile solutions in practice.
