Time,space and technology in the working‐home: an unsettled nexus

The research reported here draws upon four homes in Melbourne, Australia, where variable practices and strategies in the use of information and communication technologies are adopted in negotiating the temporal and spatial dynamics of the working‐home. Informed by theories from Science and Technology Studies, we argue that these strategies arise in concernful relation with others—both human and non‐human—that enable and constrain the possibilities for action.     

‘Work always wins’: client colonisation,time management and the anxieties of connected freelancers

This article focuses on ‘connected freelancers’ as a category of teleworkers and examines the pressures placed on their work‐home balance by their relationship with clients. Based on diaries, questionnaires and interviews, it reveals that, while connected freelancers do not generally work excessively long hours, they do work irregular hours. This is because ‘work always wins’ in a conflict with domestic commitments, a phenomenon the article dubs ‘client colonisation’. Client colonisation was a source of anxiety for respondents, who found themselves continually thinking about the current and future projects on which their livelihoods depend. The article illustrates the porous ways in which they interleave work with non‐work activities and contrasts traditional ‘monochronic’ forms of work with emerging ‘polychronic’ forms, which erode work‐home boundaries. It concludes that a new model of work—one in which individual patterns of control over work‐home balance are paramount—already coexists alongside traditional models but is still insufficiently socially understood and accepted.     

Servicing the media: freelancing, teleworking and 'enterprising' careers

This article examines the working lives of people offering services to the media on a freelance basis. Almost all work from home using information and communication technologies but isolation in the home is not the norm as most maintain extensive personal networks in the industry. Nevertheless, popular imagery of the 'electronic cottage' and the 'virtual organisation only superficially capture their experiences. Insecurity and weakness in the market are suggested by histories of redundancy and dependence on single client organisations including former employers.     

Information gaps: myth or reality?

The rising importance of information technologies is said to threaten ever wider gaps between groups in society. This article considers to what extent the warning are valid. The author traces the history of the introduction in the USA of the telephone, electricity and other innovations and finds that all have followed the same pattern — access was limited in the early stages. He concludes that there is no need to act precipitously to improve access to information technologies and, in any case, the type of action needed is not at all obvious. As the world's work force becomes wealthier and technology costs decline, the differences in all aspects of living standards will decrease.     

The Effect of "Front-Loading" Problem-Solving on Product Development Performance

In recent years, there has been a growing interest in the link between problem‐solving capabilities and product development performance. In this article, the authors apply a problem‐solving perspective to the management of product development and suggest how shifting the identification and solving of problems—a concept that they define as front‐loading—can reduce development time and cost and thus free up resources to be more innovative in the marketplace. The authors develop a framework of front‐loading problem‐solving and present related examples and case evidence from development practice. These examples include Boeing's and Chrysler's experience with the use of “digital mock‐ups” to identify interference problems that are very costly to solve if identified further downstream—sometimes as late as during or—after first full‐scale assembly. In the article, the authors propose that front‐loading can be achieved using a number of different approaches, two of which are discussed in detail: (1) project‐to‐project knowledge transfer—leverage previous projects by transferring problem and solution‐specific information to new projects; and (2) rapid problem‐solving—leverage advanced technologies and methods to increase the overall rate at which development problems are identified and solved. Methods for improving project‐to‐project knowledge transfer include the effective use of “postmortems,” which are records of post‐project learning and thus can be instrumental in carrying forward the knowledge from current and past projects. As the article suggests, rapid problem‐solving can be achieved by optimally combining new technologies (such as computer simulation) that allow for faster problem‐solving cycles with traditional technologies (such as late stage prototypes), which usually provide higher fidelity. A field study of front‐loading at Toyota Motor Corporation shows how a systematic effort to front‐load its development process has, in effect, shifted problem‐identification and problem‐solving to earlier stages of product development. They conclude the article with a discussion of other approaches to front‐load problem‐solving in product development and propose how a problem‐solving perspective can help managers to build capabilities for higher development performance.     

The diffusion of new telecommunication technologies

This article assesses the recent diffusion of new telecommunication technologies. Drawing upon an historical framework, the authors find that new technologies face significant barriers to rapid penetration in the home and office. Data on cable television, electronic text services, teleconferencing and alternative video distribution technologies are analysed to highlight the constraints facing the growth of new telecommunications services.     

When are technologies disruptive? a demand‐based view of the emergence of competition

By identifying the possibility that technologies with inferior performance can displace established incumbents, the notion of disruptive technologies, pioneered by Christensen (1997), has had a profound effect on the way in which scholars and managers approach technology competition. While the phenomenon of disruptive technologies has been well documented, the underlying theoretical drivers of technology disruption are less well understood. This article identifies the demand conditions that enable disruptive dynamics. By examining how consumers evaluate technology and how this evaluation changes as performance improves, it offers new theoretical insight into the impact of the structure of the demand environment on competitive dynamics. Two new constructs—preference overlap and preference symmetry—are introduced to characterize the relationships among the preferences of different market segments. The article presents a formal model that examines how these relationships lead to the emergence of different competitive regimes. The model is analyzed using computer simulation. The theory and model results hold implications for understanding the dynamics of disruptive technologies and suggest new indicators for assessing disruptive threats.

Power/knowledge and impact assessment: creating new spaces for expertise in international development

Impact assessment is an important methodology in information and communication technologies for development. It presents the potential to change power knowledge relations between donors, non‐governmental organizations and beneficiaries. Impact assessment offers a new and subtle form of control—shaped by and shaping expertise—influencing how we understand and undertake development.     

"Managing" Learning by Doing: An Empirical Study in Semiconductor Manufacturing

This article examines the contributions of human resource and organizational practices to the development and supply chain management interface. It addresses this issue in the context of the semiconductor industry by highlighting the importance of these practices for learning‐based improvement in manufacturing. One of the most important factors for competitiveness in the semiconductor industry is the ability to manufacture new process technologies with high yields and low cycle times. The more effective management of new process technologies within the manufacturing facility aids firms in managing production costs, volumes, and inventories. Efficient management of new process development and introduction translates into enhanced internal supply chain management performance by improving the design of internal workflows, manufacturing performance, and the acquisition and installation of new manufacturing processes. Because much of the knowledge that underpins semiconductor manufacturing is idiosyncratic, however, firm‐level differences in human resource and organizational practices are likely to have consequences for performance. The article derives learning curve models of the rate of improvement in manufacturing yield (i.e., the rate of learning) and cycle time (i.e., the speed of production) following the introduction of a new process technology in a manufacturing facility. It then tests the influence of the use by semiconductor manufacturers of teams for problem solving and intrafirm knowledge transfer, the level of internal adoption of information technology (IT), and more extensive and effective workflow and production scheduling systems on manufacturing performance. It finds that the manners in which semiconductor manufacturers allocate engineering resources to problem‐solving activities, utilize information technology in the manufacturing facility, schedule production, and control the “shop floor” influence the levels and rates of improvement in both manufacturing performance measures. The article makes several contributions to the literature on product and process development and, accordingly, to research on the product development/supply chain interface. In particular, the model of organizational‐based learning provides a better understanding of the determinants of learning‐based performance improvement. In particular, better manufacturing performance results not strictly from greater cumulative volume but also from the actions of managers that affect the organization of establishment‐level problem‐solving activities and information exchange. The article also demonstrates that human resource and organizational practices in both the development and the adoption of new process technologies improve manufacturing performance by accelerating new product introduction, improving workflow, and enhancing the efficiency of manufacturing processes.     

Policy research for information activities: The OECD programme on information,computers and communications policy

The Working Party on Information, Computers and Communications Policy of the OECD has been created to carry out extensive research in preparation for the integrated policies that must be implemented to give direction to the development and merging of information technologies. The author discusses the activities and objectives of the research programme, focusing on that part of it which involves the macroeconomic analysis of information activities.     

Envy,comparison costs,and the economic theory of the firm

An economic theory of the firm must explain both when firms supplant markets and when markets supplant firms. While theories of when markets fail are well developed, the extant literature provides a less than adequate explanation of why and when hierarchies fail and of actions managers take to mitigate such failure. In this article, we seek to develop a more complete theory of the firm by theorizing about the causes and consequences of organizational failure. Our theory focuses on the concept of social comparison costs that arise through social comparison processes and envy. While transaction costs in the market provide an impetus to move activities inside the boundaries of the firm, we argue that envy and resulting social comparison costs motivate moving activities outside the boundary of the firm. More specifically, our theory provides an explanation for ‘managerial’ diseconomies of both scale and scope—arguments that are independent from traditional measurement, rent seeking, and competency arguments—that provides new insights into the theory of the firm. In our theory, hierarchies fail as they expand in scale because social comparison costs imposed on firms escalate and hinder the capacity of managers to optimally structure incentives and production. Further, hierarchy fails as a firm expands in scope for the simple reason that the costs of differentially structuring compensation within the firm to match the increasing diversity of activities also rises with increasing scope. In addition, we explore how social comparison costs influence the design of the firm through selection of production technologies and compensation structures within the firm.

What is family friendly about the workplace in the home? The case of self‐employed parents and their children

This article draws upon the narratives of self-employed parents, their partners and children in order to examine the 'family friendliness' of making the home a site of paid work. While not fitting narrow definitions of 'teleworker' the subjects daily confronted the use of space in their homes, and access to technologies there.     

Priorities in agricultural research

This article is a personal reflection on priorities in agricultural research, priorities which can only be seriously formulated in relation to an overall strategy for agriculture, food and nutrition. Dr Ulbricht identifies three main areas of agricultural research — that which is universal in application and involves a substantial increase in knowledge, that which is generally universal in application but is defining new technologies and that which is directed to defining new technologies for specific local situations. He emphasises the importance of the latter which has been greatly neglected and is of particular importance in developing countries.     

Computing Technology for the Home: Product Strategies for the Next Generation

Recent developments in the personal and home computer marketplace have raised questions about the effectiveness of current product strategies. In this article, Alladi Venkatesh and Nicholas Vitalari focus on the home computer market which continues to evolve in different ways. Specifically, they identify five technologically oriented product strategies, the electronic game technology strategy, the children's educational focus strategy, the office technology transfer strategy, the consumer electronic interchange strategy, and the home information systems strategy. The authors feel that the home information systems strategy may have the best long-run potential for success because it comes closest to meeting the needs of the changing household.     

Information and communications technology use,e‐government,pain and stress amongst public servants

This paper examines information and communications technologies use, work intensity, technology preference, respondent characteristics, pain and stress in 240 New Zealand public servants across six agencies. In particular, we find that four variables are the most consistent predictors of pain—hours using a cell phone, stress, female gender and one's salary.     

Wanted — wise policy not restrictive regulation

This article begins by restating some familiar tenets of information processing and telecommunications theory: that our emerging post-industrial economy is becoming increasingly service-oriented with a corresponding emphasis being placed upon information-intensive activities;¹ that technical improvements in telecommunications systems are forthcoming at an almost exponential rate of increase;² that a wide array of developed or developing telecommunications systems (including computer-based word processing, cable/satellite TV, interactive video, videotext, etc) are being considered for possible application in varied settings (ranging from the home to the office to the delivery of governmental services).     

Business travellers' connections to home: ICTs supporting work‐life balance

This paper examines the role of information communication technology in enabling connections to home for work‐related travellers. Although digital connectivity for work‐related tasks are well researched, the use of digital technology for home communication is under‐researched. The study draws on a qualitative study of UK‐based organisations and business travellers to explore how these travellers use ICTs for personal use while ‘on the move’. The findings reveal that organisations are supportive of work‐life balance for employees, but fail to consider specific needs of those whose work takes them away from home. For business travellers, insights are gained into practices around connecting to home and the value of this virtual presence for relationships with family while absent and work‐life balance. The study identifies and discusses practice occurring around three activities; checking in, maintaining relationships with home and sharing experiences.
