Forscher und Praktiker im Gebiet intraorganisationaler IT-Governance beschäftigen sich seit Längerem intensiv mit den organisatorischen Strukturen IT-bezogener Entscheidungen. Ergebnisse aus kontingenztheoretischen Analysen ha-ben gezeigt, dass eine effektive Steuerung der IT durch situative Faktoren bedingt ist. Im noch jungen Forschungszweig der IT-Netzwerk-Governance fand dies noch keine Bet...

It is believed by many scholars that a small and medium-sized enterprise (SME) cannot be seen through the lens of a large firm. Theories which explain IT governance in large organizations and methodologies used by practitioners can therefore not be extrapolated to SMEs, which have a completely different economic, cultural and managerial environment. SMEs suffer from resource poverty, have less ...

Werden Services in einem anderen Kontext wieder verwendet, ist zu berücksichtigen, dass dabei unterschiedliche Regulatorien relevant sein können. In diesem Beitrag wird ein Lösungsansatz für die Auswahl konformer Services auf Basis seman...

Via quantitative analyses of large IT-portfolio databases, we detected unique data patterns pointing to certain IT-governance rules and styles, plus their sometimes nonintuitive and negative side-effects. We grouped the most important patterns in seven categories and highlighted them separately. These patterns relate to the five fundamental parameters for IT-governance: data, control, time, cos...
