Analysing information systems evaluation: another look at an old problem

Abstract: Information systems (IS) evaluation is a thorny problem. In this paper we re-examine the area in light of recent developments in the field. Our examination begins with an example of a common contemporary IS assessment problem, viz. evaluating outsourcing. The example highlights the organizational and political issues that make evaluation fraught with difficulties. The paper argues that IS evaluation is a ‘necessary evil’ but the context in which IS are developed and used has become much more demanding and complex. A conceptual framework, first proposed in an earlier paper as a way to classify the literature, is presented and brought up to date. The framework is then used to re-examine the outsourcing example, demonstrating the usefulness of the framework.

Power to the Parties: Cohesion and Competition in the European Parliament, 1979–2001

Abstract: How cohesive are political parties in the European Parliament? What coalitions form and why? The answers to these questions are central for understanding the impact of the European Parliament on European Union policies. These questions are also central in the study of legislative behaviour in general. We collected the total population of roll-call votes in the European Parliament, from the first elections in 1979 to the end of 2001 (over 11,500 votes). The data show growing party cohesion despite growing internal national and ideological diversity within the European party groups. We also find that the distance between parties on the left-right dimension is the strongest predictor of coalition patterns. We conclude that increased power of the European Parliament has meant increased power for the transnational parties, via increased internal party cohesion and inter-party competition.

Do Friends and Relatives Really Help in Getting a Good Job

Abstract: Informal contacts are extensively used by both firms and workers to find jobs and fill vacancies. The common wisdom in the economic literature is that jobs created through this channel are of better quality and pay higher wages than jobs created through formal methods. This paper explores the empirical evidence for European countries using the European Community Household Panel (ECHP) and discovers a large cross-country as well as cross-industry variation in the wage differentials between jobs found through informal and formal methods. Across countries and industries wage premiums and wage penalties to finding jobs through personal contacts are equally frequent. This paper argues that such variation can be explained by looking at firms' recruitment strategies. In labour markets where employers invest largely in formal recruitment activities, matches created through this channel are likely to be of average better quality than those created through informal networks. A simple theoretical model is used to show that employers invest more in recruitment for high productivity jobs and for positions that require considerable training. The empirical predictions of the theory are successfully tested using industry-level data on recruitment costs.

New games, new rules: big data and the changing context of strategy

Abstract: Big data and the mechanisms by which it is produced and disseminated introduce important changes in the ways information is generated and made relevant for organizations. Big data often represents miscellaneous records of the whereabouts of large and shifting online crowds. It is frequently agnostic, in the sense of being produced for generic purposes or purposes different from those sought by big data crunching. It is based on varying formats and modes of communication (e.g., texts, image and sound), raising severe problems of semiotic translation and meaning compatibility. Crucially, the usefulness of big data rests on their steady updatability, a condition that reduces the time span within which this data is useful or relevant. Jointly, these attributes challenge established rules of strategy making as these are manifested in the canons of procuring structured information of lasting value that addresses specific and long-term organizational objectives. The developments underlying big data thus seem to carry important implications for strategy making, and the data and information practices with which strategy has been associated. We conclude by placing the understanding of these changes within the wider social and institutional context of longstanding data practices and the significance they carry for management and organizations.
