AbstractQuality requirements are vital to developing successful software products. However, there exist evidence that quality requirements are managed mostly in an “ad hoc” manner and down-prioritized. This may result in insecure, unstable, slow products, and unhappy customers. We have developed a conceptual model for the scoping process of quality requirements – QREME – and an assessment model – Q-REPM – for companies to benchmark when evaluating and improving their quality requirements practices. Our model balances an upfront forward-loop with a data-driven feedback-loop. Furthermore, it addresses both strategic and operational decisions. We have evaluated the model in a multi-case study at two companies in Sweden and three companies in The Netherlands. We assessed the scoping process practices for quality requirements and provided improvement recommendations for which practices to improve. The study confirms the existence of the constructs underlying QREME. The companies perform, in the median, 24% of the suggested actions in Q-REPM. None of the companies work data-driven with their quality requirements, even though four out of five companies could technically do so. Furthermore, on the strategic level, quality requirements practices are not systematically performed by any of the companies. The conceptual model and assessment model capture a relevant view of the quality requirements practices and offer relevant improvement proposals. However, we believe there is a need for coupling quality requirements practices to internal and external success factors to motive companies to change their ways of working. We also see improvement potential in the area of business intelligence for QREME in selecting data sources and relevant stakeholders.

The Technical Publications team at Sybase, Inc. maintains many thousands of pages of user documentation and online help topics for a diverse set of software products. Writing teams work in nine locations around the globe; a given project often involves writers from multiple locations. To achieve greater efficiency, increase opportunities for reuse, and improve user experience, the department is moving to the Darwin Information Typing Architecture (DITA) from a variety of source formats. Early adopters realized the need for more detailed information models for several types of content than required by the DITA standard. This chapter discusses why models are a critical component to successful collaborative writing, especially for topic-oriented content. It then describes the collaborative processes and tools by which Sybase® Technical Publications team members propose, evaluate, develop, test, and enforce new content models, challenges encountered, and key success factors.

This article investigates the Trump campaign’s strategic use of digital platforms and their affordances and norms that contribute to a technological performance of populism. To do so, I build on theories of populism as a performance, rather than a set of identifiable qualities, and make a theoretical intervention calling for the need to add a material and technological focus to how scholars approach the concept in our contemporary media environment. This article presents a model for understanding populist affordances as those that center “the people” to various degrees, and applies that model in a case study of how campaigns in the 2016 US presidential race engaged in a technological performance of populism across a variety of platforms, including email, Twitter, Instagram, Facebook, and campaign-created mobile apps. Central to this analysis are campaign strategies of controlled interactivity, amateurism, participatory/user-generated content, and data-driven campaigning.

Playability is a key concept in game studies defining the overall quality of video games. Although its definition and frameworks are widely studied, methods to analyze and evaluate the playability of video games are still limited. Using heuristics for playability evaluation has long been the mainstream with its usefulness in detecting playability issues during game development well acknowledged. However, such a method falls short in evaluating the overall playability of video games as published software products and understanding the genuine needs of players. Thus, this paper proposes an approach to analyze the playability of video games by mining a large number of players’ opinions from their reviews. Guided by the game-as-system definition of playability, the approach is a data mining pipeline where sentiment analysis, binary classification, multi-label text classification, and topic modeling are sequentially performed. We also conducted a case study on a particular video game product with its 99,993 player reviews on the Steam platform. The results show that such a review-data-driven method can effectively evaluate the perceived quality of video games and enumerate their merits and defects in terms of playability.

Despite Volunteered Geographic Information (VGI) activities are now extremely helpful in a number of scientific applications, researchers and decision makers oppose some resistance to the usage of volunteered contributions, due to quality issues. Several methods and workflows have been proposed to face quality issues in different VGI projects, usually built ad-hoc for specific datasets, thus resulting neither extensible nor transferable. In order to overcome this weakness, the authors propose to perform an user-driven assessment on VGI items in order to filter only those that satisfy minimally acceptable quality levels defined according to their specific quality requirements and project goals. In the present work the users, i.e., information consumers, are seen as decision makers and are allowed to set the minimum acceptable quality levels Thus the approach proposes a user driven assessment of the fitness for use of VGI items. The paper first briefly presents a view on VGI components and suitable quality indices, then it describes a logic architecture for managing them and for enabling a querying mechanism to the datasets. The approach is finally exemplified with a case study simulation.

Cross-organizational electronic collaboration is about to gain significant momentum and facilitates the emergence of a globally networked information service economy. However, existing solutions for the realization of such business relationships still exhibit weaknesses with respect to both managerial and technological aspects. In this work, we propose a service-oriented reference architecture for electronic business media that overcomes the drawbacks of today’s business-to-business (B2B) software products and services. Based on the St. Gallen media reference model, this reference architecture incorporates the design principle of modularity that proved critical for the success of numerous artifacts in other more mature industries. In particular, we investigate and revisit the principle of modularity with respect to its role in the computer industry and transfer it to the context of organizing and implementing electronic cross-company collaboration. On the basis of a case study in the field of public administration in Switzerland, we show its real-world applicability and its improvement potential.

Abstract How does tragedy, primarily a dramatic-literary experience, shape politics? While scholars have mostly looked to classical tragedy and expressions of public mourning to answer this, I employ a policy-oriented case study to do so: the politics of Daniel Patrick Moynihan. Widely known for his data-driven social science, I want to suggest the counterintuitive claim that the popular senator from New York was ironically also influenced deeply by literary tragedy. This article demonstrates how Moynihan cultivated a set of tragic sensibilities that informed his realist political calculations and implanted in his policies a tragic awareness that limited the goals of what government could achieve, while helping define what it should and how. Rather than evaluate the validity of his controversial proposals from the 1960s, I offer a critical reexamination that highlights the tragic impulses coloring them. In the process, I conceptualize a politics of tragedy as a “tamed” form of postwar liberalism.

Mass transit remains the most efficient way to service a densely packed commuter population. However, reliability issues and increasing competition in the transportation space have led to declining ridership across the United States, and transit agencies must also operate under tight budget constraints. Recent attempts at using bus network redesign to improve ridership have attracted attention from various transit authorities. However, the analysis seems to rely on ad hoc methods, for example, considering each line in isolation and using manual incremental adjustments with backtracking. We provide a holistic approach to designing a transit network using column generation. Our approach scales to hundreds of stops, and we demonstrate its usefulness on a case study with real data from Boston.

Financial inclusion and startup are two topics, which recently get attention of academic researchers and policy makers in Vietnam. One of the important factors for setting up a successful startup is the financial capability of the owners. Therefore, financial inclusion has a strong correlation with startup establishment. This article tested the effects of several factors in financial index (findex) developed by World Bank on startup establishment in some OECD countries. The result showed that borrowing from friends and relatives along with from credit institutions and opening a debit account at banks have  significant impacts on startup establishment in these countries. Finally, the article presented several recommendations for policy makers to stimulate the startup growth in Vietnam in the next time.
