Being Interrupted by Instant Messaging: Does it Matter Who is Interrupting - The Boss or The Coworker?

Instant messenger is being rapidly deployed in the workplace. Current studies largely focus on the adoption of IM and how IM is used. Little research has been conducted to understand the potential impact of using IM in the workplace. This paper contributes to the literature on Instant Messaging and task performance by theorizing and empirically testing how some technological features of IM could intertwine with social characteristics and jointly influence user task performance and perceived workload. We also study the impact of perceived task complexity on task performance and perceived workload. The effect of interruption on task completion time is dependent upon the hierarchy level of message sender. Interruptions from a supervisor were found to reduce primary task completion time whereas interruptions from a peer increase primary task completion time. In addition, interruptions from a supervisor aggravate the negative impact of interruptions on task quality

Theorizing the Multilevel Effects of Interruptions and the Role of Communication Technology

Our understanding of how interrupting the work of an individual affects group outcomes and the role of communication technologies (CT) in shaping these effects is limited. Drawing upon coordination theory and the literatures on computer-mediated communication and interruptions, this paper develops a multilevel theory of work interruptions. It suggests that interruptions that target individuals can also affect other group members through various ripple effects and a cross-level direct effect. We also discuss how the usage of five CT capabilities during interruption episodes can moderate the impact of interruptions at the individual and group levels. Our theoretical model draws attention to the importance of examining the individual-to-group processes to better understand the impact of interruptions in group environments. Additionally, by accounting for the role of the use of CT capabilities during interruption episodes, our work contributes to both the interruptions literature, which dedicates scant attention to the interrupting media, and to IS research on media use and media effects

Email stress and desired email use

This thesis is about workplace stress due to email and computer-mediated communication use. Rather than focusing on email-specific constructs such as email overload, email interruptions or email use outside working hours, it draws an overarching construct of ‘email stress’ based on previous theories of traditional workplace stress. This cross-disciplinary approach emphasizes the individually appraised nature of email stress. As a result, the thesis gives a central importance to individuals using email and, more importantly, to their desired email use. The thesis is based on a three-stage multi-method design involving quantitative surveys and qualitative interviews. The results of these studies are part of the four self-sufficient papers composing the thesis. While the papers make their own contributions, they also build on one another to advance the understanding of email stress as being a kind of stress that is individually appraised and that affects workplace well-being. The papers adapt theories of workplace stress, such as Person-Environment Fit and Cybernetics, to the study of email stress, and empirically validate these adaptations. They reveal how email stress can be the result of unfulfilled desires in terms of email use or a reason for desiring fewer emails. As employees do not often have control over their email use, the findings encourage the emergence of a more empathetic organizational culture taking into account individuals’ desires in terms of email use

Information and communication technology demands: outcomes and interventions

International audienceThe purpose of this paper is to review four demands employees face when communicating through information and communication technologies (ICTs). We review the outcomes associated with each demand and discuss relevant interventions to provide a set of evidence-based recommendations

Understanding receptivity to interruptions in mobile human-computer interaction

Interruptions have a profound impact on our attentional orientation in everyday life. Recent advances in mobile information technology increase the number of potentially disruptive notifications on mobile devices by an increasing availability of services. Understanding the contextual intricacies that make us receptive to these interruptions is paramount to devising technology that supports interruption management. This thesis makes a number of contributions to the methodology of studying mobile experiences in situ, understanding receptivity to interruptions, and designing context-sensitive systems. This thesis presents a series of real-world studies that investigate opportune moments for interruptions in mobile settings. In order to facilitate the study of the multi-faceted ways opportune moments surface from participants' involvement in the world this thesis develops: - a model of the contextual factors that interact to guide receptivity to interruptions, and - an adaptation of the Experience-Sampling Method (ESM) to capture behavioural response to interruptions in situ. In two naturalistic experiments, participants' experiences of being interrupted on a mobile phone are sampled as they go about their everyday lives. In a field study, participants' experiences are observed and recorded as they use a notification-driven mobile application to create photo-stories in a theme park. Experiment 1 explores the effects of content and time of delivery of the interruption. The results show that receptivity to text messages is significantly affected by message content, while scheduling one's own interruption times in advance does not improve receptivity over randomly timed interruptions. Experiment 2 investigates the hypothesis that opportune moments to deliver notifications are located at the endings of episodes of mobile interaction such as texting and calling. This notification strategy is supported by significant effects in behavioural measures of receptivity, while self-reports and interviews reveal complexities in the subjective experience of the interruption. By employing a mixed methods approach of interviews, observations and an analysis of system logs in the field study, it is shown that participants appreciated location-based notifications as prompts to foreground the application during relative 'downtimes' from other activities. However, an unexpected quantity of redundant notifications meant that visitors soon habituated to and eventually ignored them, which suggests careful, sparing use of notifications in interactive experiences. Overall, the studies showed that contextual mediation of the timing of interruptions (e.g. by phone activity in Experiment 2 and opportune places in the field study) is more likely to lead to interruptions at opportune moments than when participants schedule their own interruptions. However, momentary receptivity and responsiveness to an interruption is determined by the complex and situated interactions of local and relational contextual factors. These contextual factors are captured in a model of receptivity that underlies the interruption process. The studies highlight implications for the design of systems that seek to manage interruptions by adapting the timing of interruptions to the user's situation. In particular, applications to manage interruptions in personal communication and pervasive experiences are considered
