摘要：The computing industry is gradually evolving to cater to the demand for software-as-a-service (SaaS). Two core competencies that have emerged over the past few years are that of the application service providers (ASPs) and the application infrastructure providers (AIPs). The arrangements between them result in system dynamics that is typical in supply chain networks. We examine the performance of an SaaS set up under different coordination strategies between these two players. Our analysis ind...

摘要：With the move to an information-based economy, financial services has become a key contributor to the U.S. gross domestic product. Even as consolidation reduces the number of banks, small banks with under $100 million in assets continue to report higher profit margins than large banks with over $100 million in assets. Lacking scale, small banks employ a service-oriented business strategy (customer intimacy), whereas large banks focus on productivity and throughput (operational excellence). Inf...

摘要：The increasing importance of information technology (IT) services in the global economy prompts researchers in the field of information systems (IS) to give special attention to the foundations of managerial and technical knowledge in this emerging arena of knowledge. Already we have seen the computer science discipline embrace the challenges of finding new directions in design science toward making services-oriented computing approaches more effective, setting the stage for the development of...

摘要：Service-oriented architecture (SOA) is one of the most discussed topics in the information systems (IS) discipline. While most computer scientists agree that the service-oriented paradigm has clear benefits in terms of technical quality attributes, it has been difficult to justify SOA economically. The few studies that have investigated the strategic and economic aspects of SOA are mostly exploratory and lack a more comprehensive framework for understanding the sources of its economic potentia...

摘要：The importance of building relationships with customers and trust in the services provider is well documented in the marketing literature. Conceptually, we extend this logic to the context of internal information technology (IT) services operations through the notion of the service delivery chain. The purpose of the study is to examine how key service mechanisms in operational IT implementation are related to employee perceptions of actual system benefits and trust in the IT services provider....

摘要：An important task for managers in information technology (IT) service settings is the judgment of service performance. The complex and intangible nature of IT services, however, renders this task especially difficult. We use a sample of 85 outsourced software development projects to test for the presence of the input bias, which is defined as the systematic misuse of nondiagnostic input information in forming managerial judgments of outcomes. The service outcome we examine is process performan...

摘要：In an information technology services outsourcing arrangement, variance in demand volume and individual user preferences pose significant challenges to the provider organization in making resource allocation decisions. Such variations affect service levels, especially under fixed resource constraints. We explore the possible role of periodic demand information sharing and subsequent resource-level adjustments as a means of addressing issues arising from demand variation. As information exchang...

摘要：Service-oriented architecture (SOA) has been promoted as a technology that can enhance information systems agility, interoperability between applications, deployment flexibility, and reusability. As with any new information technology (IT), the decision to adopt SOA cannot be taken lightly, given the nontrivial investment in economic and personnel resources. The complexity associated with industry-wide diffusion, coupled with organization, industry, and environment factors, contributes to a la...

摘要：We examine contract choices in the provision of software-as-a-service (SaaS), which is a business innovation that transforms information technology (IT) resources into a continuously provided service. We draw upon agency theory and modularity theory to propose that one of the central challenges in service disaggregation is that of knowledge interdependencies across client and provider organizations. The resulting lack of verifiability of certain tasks results in a multitask agency problem. Our...
