Control of Flexible Software Development Under Uncertainty

When should software development teams have the flexibility to modify their directions and how do we balance that flexibility with controls essential to produce acceptable outcomes? We use dynamic capabilities theory and an extension of control theory to understand these questions. This work is examined in a case study. Our results demonstrate that flexibility may be needed when the starting conditions are uncertain and that effective control in these situations requires use of traditional controls plus a new type of control we term emergent outcome control.

Technology Requirements and Work Group Communication for Telecommuters

As organizations implement more and more distributed work arrangements such as telecommuting, there is a need to understand the determinants of success of this new work setting. This research investigated three variables believed to impact outcomes in telecommuting: the availability of information system technology, the availability of communication technologies, and the communication patterns of telecommuters within their work groups. Two perspectives are used in this study. The direct effects of these three variables on perceived productivity, performance, and satisfaction were tested. A second perspective, based on the concept of fit and contingency theory, posits that successful telecommuting outcomes, measured by perceived productivity, performance, and satisfaction, are predicted by interactions between these independent variables. The study was conducted by surveying multiple respondents from different organizations who were members of work groups in which some or all employees were telecommuters. The results indicate that technology variables positively impact productivity, performance, and satisfaction of telecommuters, while the interaction between the technology variables is significant in predicting perceived productivity. Work group communication, as measured by the centrality of individuals, negatively affects perceived productivity and performance. The paper presents a discussion of the theoretical significance of these findings, and offers recommendations for future research.

Reviewing software diagrams: a cognitive study

Reviews and inspections of software artifacts throughout the development life cycle are effective techniques for identifying defects and improving software quality. While review methods for text-based artifacts (e.g., code) are well understood, very little guidance is available for performing reviews of software diagrams, which are rapidly becoming the dominant form of software specification and design. Drawing upon human cognitive theory, we study how 12 experienced software developers perform individual reviews on a software design containing two types of diagrams: entity-relationship diagrams and data flow diagrams. Verbal protocol methods are employed to describe and analyze defect search patterns among the software artifacts, both text and diagrams, within the design. Results indicate that search patterns that rapidly switch between the two design diagrams are the most effective. These findings support the cognitive theory thesis that how an individual processes information impacts processing success. We conclude with specific recommendations for improving the practice of reviewing software diagrams.

The impacts of quality and productivity perceptions on the use of software process improvement innovations

Numerous software process improvement (SPI) innovations have been proposed to improve software development productivity and system quality; however, their diffusion in practice has been disappointing. This research investigates the adoption of the Personal Software Process on industrial software projects. Quantitative and qualitative analyses reveal that perceived increases in software quality and development productivity, project management benefits, and innovation fit to development tasks, enhance the usefulness of the innovation to developers. Results underscore the need to enrich current technology acceptance models with these constructs, and serve to encourage project managers to adopt formal SPI methods if developers perceive the methods will have positive impacts on their productivity and system quality.

Software localization for Internet software, issues and methods

For use by a global audience, Web sites must be adapted to many local requirements. This article examines key issues in such adaptation (termed localization), considers the costs and specific aspects of software that must be localized, and presents an approach for analyzing and documenting software localization. The article is based on a review of relevant literature, meetings with localization industry representatives, and an ongoing participant observation in a global telehealth company. Examples from the company illustrate the localization issues and their possible outcomes or solutions.

Conflict in collaborative software development

Pair Programming is an innovative collaborative software development methodology. Anecdotal and empirical evidence suggests that this agile development method produces better quality software in reduced time with higher levels of developer satisfaction. To date, little explanation has been offered as to why these improved performance outcomes occur. In this qualitative study, we focus on how individual differences, and specifically task conflict, impact results of the collaborative software development process and related outcomes. We illustrate that low to moderate levels of task conflict actually enhance performance, while high levels mitigate otherwise anticipated positive results.

Controlled experimentation on adaptations of pair programming

The use of agile methods is growing in industrial practice due to the documented benefits of increased software quality, shared programmer expertise, and user satisfaction. These methods include pair programming (two programmers working side-by-side producing the code) and test-driven approaches (test cases written first to prepare for coding). In practice, software development organizations adapt agile methods to their environment. The purpose of this research is to understand better the impacts of adapting these methods. We perform a set of controlled experiments to investigate how adaptations, or variations, to the pair programming method impact programming performance and user satisfaction. We find that method variations do influence programming results. In particular, better performance and satisfaction outcomes are achieved when the pair programming is performed in face-to-face versus virtual settings, in combination with the test-driven approach, and with more experienced programmers. We also find that limiting the extent of collaboration can be effective, especially when programmers are more experienced. These experimental results provide a rigorous foundation for deciding how to adapt pair programming methods into specific project contexts.

Telemedicine: Technology mediated service relationship, encounter, or something else?

PURPOSE Service interactions between service providers and health care consumers happen daily in health care organizations, and can occur face-to-face or through mediating technology. We use the demanding and rich environment of telemedicine to better understand the nature of the real time service-encounter interactions among the human and technology actors engaged in the process and to inform telemedicine providers about key factors to consider in telemedicine design. METHODS We conducted a case study of medical video conferencing (MVC) for the delivery of patient healthcare (a form of telemedicine) using multiple data collection and analysis techniques involving a range of telemedicine stakeholders. RESULTS The research reveals that telemedicine requires a new kind of service relationship, an Advanced Encounter, with unique relationships between the telemedicine service providers, presenters, patients, and technology. Seven facilitating factors for the Advanced Encounter of telemedicine are identified and discussed, including the telemedicine servicescape: a set of supporting structures that are critical to telemedicine success. CONCLUSIONS Key contributions are a deep understanding of the relationships between telemedicine actors, and the organizational actions needed to deploy a technology-mediated telemedicine service.

Telemedicine encounter quality: comparing patient and provider perspectives of a socio-technical system

The effectiveness of the telemedicine encounter is dependent on the use of state-of-the-art technology and the quality of the technology-based interactions. We take a socio-technical approach to understanding quality during telemedicine encounters. This approach has not been well studied in telemedicine service encounter research. To enrich understanding, we use a multimethod (direct observation, interview, focus group, survey) field study to collect and interpret a rich set of data. We conduct this study from two perspectives. First, we focus on the perceptions of the medical providers (e.g. physicians) who directly use the technology and are accountable for patient care. We then compare provider perspectives to those of patients, who act as indirect users of telemedicine technology and are the ultimate consumers of health care services provided via telemedicine. The result of this field study is a comparative framework of quality attributes for telemedicine service encounters that prioritizes the attributes from the provider and patient perspectives.
