Outsourcing to an unknown workforce: exploring opensourcing as a global sourcing strategy

Abstract: This paper presents a psychological contract perspective on the use of the open source development model as a global sourcing strategy-opensourcing, as we term it here-whereby commercial companies and open source communities collaborate on development of software of commercial interest to the company. Building on previous research on information systems outsourcing, a theoretical framework for exploring the opensourcing phenomenon is derived. The first phase of the research concerned qualitative case studies involving three commercial organizations (IONA Technologies, Philips Medical Systems, and Telefonica) that had "liberated" what had hitherto been proprietary software and sought to grow a global open source community around their product. We followed this with a large-scale survey involving additional exemplars of the phenomenon. The study identifies a number of symmetrical and complementary customer and community obligations that are associated with opensourcing success. We also identify a number of tension points on which customer and community perceptions tend to vary. Overall the key watchwords for opensourcing are openness, trust, tact, professionalism, transparency, and complementariness: The customer and community need to establish a trusted partnership of shared responsibility in building an overall opensourcing ecosystem. The study reveals an ongoing shift from OSS as a community of individual developers to OSS as a community of commercial organizations, primarily small to medium-sized enterprises. It also reveals that opensourcing provides ample opportunity for companies to headhunt top developers, hence moving from outsourcing to a largely unknown OSS workforce toward recruitment of developers from a global open source community whose talents have become known as a result of the opensourcing experience.

Global Software Development Challenges: A Case Study on Temporal, Geographical and Socio-Cultural Distance

Abstract: Global software development (GSD) is a phenomenon that is receiving considerable interest from companies all over the world. In GSD, stakeholders from different national and organizational cultures are involved in developing software and the many benefits include access to a large labour pool, cost advantage and round-the-clock development. However, GSD is technologically and organizationally complex and presents a variety of challenges to be managed by the software development team. In particular, temporal, geographical and socio-cultural distances impose problems not experienced in traditional systems development. In this paper, we present findings from a case study in which we explore the particular challenges associated with managing GSD. Our study also reveals some of the solutions that are used to deal with these challenges. We do so by empirical investigation at three US based GSD companies operating in Ireland. Based on qualitative interviews we present challenges related to temporal, geographical and socio-cultural distance.

Global software development: where are the benefits?

Abstract: IntroductionGlobal Software Development (GSD) is increasingly becoming the normal practice in the software industry, readily evidenced by U.S. estimates that the value of the offshore software development market has increased 25-fold over the past 10 years, to the extent that one-quarter of U.S. spending on application development, integration and management services is expected to go off-shore according to recent predictions. There are many potential benefits that can arise from GSD. The most frequently cited one is that of reduced development costs due to the salary savings possible. Also, GSD can lead to reduced development duration due to greater time zone effectiveness as companies practice the so-called 'follow-the-sun' software development model. GSD also affords new opportunities for cross-site modularization of development work, potential access to a larger and better-skilled developer pool, and the possibility of greater innovation, learning and transfer of best practices. Finally, GSD can facilitate closer proximity to markets and customers.However, GSD also introduces a number of challenges in relation to communication, coordination and control of the development process. These arise due to the distances involved in three dimensions -- geographical, temporal, and socio-cultural (See Figure 1). As a consequence, much research and practice has focused on trying to find ways to overcome the GSD challenges identified in Figure 1. In the literature to date, the potential benefits of GSD are usually just mentioned very briefly, if they are mentioned at all, and the realization of these benefits seems to be more or less taken for granted. The primary focus instead is on how the problems inherent in GSD might be addressed. Here, we reverse this trend and focus instead on the benefits and the extent to which they are actually being realized in practice in three global companies practicing GSD.

Agile practices reduce distance in global software development

Abstract: This article explores how agile practices can reduce three kinds of “distance” – temporal, geographical, and sociocultural – in global software development (GSD). On the basis of two in-depth case studies, specific Scrum and eXtreme Programming (XP) practices are found to be useful for reducing communication, coordination, and control problems that have been associated with GSD.

A framework for considering opportunities and threats in distributed software development

Abstract: In this paper we present an overview of the field of distributed development of software systems and applications (DD). Based on an analysis of the published literature, we consider threats to communication, coordination and control in DD caused by Temporal Distance, Geographical Distance, and Socio-Cultural Distance. The analysis results in a more complete framework for reasoning in the DD domain which should be a useful resource for both academic researchers and practitioners.

Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study

Abstract: Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.
