Service-oriented architecture (SOA) have been adopted by organizations in a wide variety of industries, however, best practices have still yet to mature. This article, which is part of a larger study on SOA, develops a normative decision model introducing key factors that influence the timing and approach of adopting a SOA. The decision model is based on the results of multiple case studies of organizations that had either employed or were considering implementing a service-oriented architecture project. The results indicate that there are four main areas an information technology (IT) manager needs to assess to determine when and how to move towards a SOA: the maturity of relevant standards, the technology gap, the organizational gap, and the nature of the benefits expected from a SOA. Analyzing these results suggest that differences in the business environment need to be considered in the decision of when and how an IT manager should pursue the move to a service-oriented architecture.

Using a multiple case studies and surveys, this article finds that factors essential to successful Service Oriented Architecture (SOA) implementations include establishing effective SOA governance, establishing SOA registries, starting with a small project, collaboration between business and IT units, strengthening trust among business units, and training. This article also explores business and IT motivations for SOA implementation and the benefits realized from this implementation. The findings from this article can provide a guidance for practitioners on the successful implementation of SOA.

The design of web and mobile applications is one of the most challenging fields of the current information technology landscape. Increasingly, companies intend to have a strong presence in the information society, which allows them to advertise their products, services, make online business, interact with customers, among others. However, the development and design of web and mobile solutions have numerous challenges and best practices that should be known and applied. In this chapter, the authors adopt a qualitative methodology based on multiple case studies that allow them to identify a total of six challenges and best practices that are later confronted and compared with the recent findings on the coverage of the topic.

Context: The coronavirus disease 2019 (COVID-19) pandemic led to a turbulent business environment, resulting in market uncertainties, frustrations, and rumors. Wrongly held beliefs—or myths—can hinder startups from turning new market opportunities into their favor (for example, by failing at diversification decisions) or undertaking wrong business decisions, e.g., diversifying in industries that have products of no real market value). Objectives: The objective of the paper is to identify the beliefs that drive the business decisions of startups in a pandemic and to isolate those beliefs that are merely myths. Further, this paper proposes strategic guidelines in the form of a framework to help startups make sound decisions that can lead to market success. Method: The two-step research method involved multiple case studies with five startups based in India, France, Italy, and Switzerland, to identify perceptual beliefs that drove strategic business decisions, followed by a case study of 36 COVID-19-solution focused startups, funded by the European Union (EU). The findings were validated through a survey that involved 102 entrepreneurs. The comparative analysis of two multiple case studies helped identify beliefs that were merely “myths”; myths that drove irrational strategic decisions, resulting in business failures. Results: The results indicate that startups make decisions in pandemic situations that are driven by seven myths, pertaining to human, intellectual, and financial resources. The decision on whether to diversify or continue in the same business operation can be divided into four strategic options of the Competency-Industry Relatedness (C-IR) framework: ignore, delay, phase-in, and diversify. Diversification in the same (or different industry) is less risky for startups if they have the skills, as needed, to diversify in related industries. Diversification in related industries helps startups leverage their experiences and learning curves (those associated with existing product lines) to adapt their existing products in new markets, or utilize their technologies to solve new problems via new products. The desired outcome for these startups should be sustainable business growth—to meet sustainability goals by contributing to the society and the economy. Conclusion: The C-IR framework is a strategic guide for startups to make business decisions based on internal factors, rather than myths. Accurately assessing skill diversity and the nature of new industries (or markets) will help startups leverage their existing resources optimally, without the need for (pricey) external funding. This will foster sustained business growth resulting in a nation economic development. Knowledge transfer from the Innovation ecosystem will further strengthen the C-IR framework effectiveness.

Global Information Technology (IT) projects span multiple locations that are typically employing different practices, adhering to different standards, and using different technologies – at the same time operating in highly diverse cultures. Differences such as these are prevalent factors that increase risk on global IT projects. Further, they are prone to changing continuously over the course of a project, with the consequence that risk becomes highly unpredictable and dynamic. This chapter proposes a framework to characterize risks within the people-process-technology-external elements of a global IT project. The framework gives particular consideration to risks that arise from interactions of multiplicities within and between those elements (i.e. dynamic risks). The principles of Service-Oriented Architecture (SOA) are adopted to propose specific strategies for mitigation of these dynamic risks. Two case studies further illustrate how those strategies can mitigate the risks.
