Dispositive Architekturen sind in vielen Unternehmen über die Zeit organisch gewachsen, wartungsintensiv und nur mit hohem Aufwand zu erweitern. Aktuelle Entwicklungen wie z.B. Bimodale IT / BI, Big Data und Digitalisierung stellen weitere Anforderungen an analytische Datenmanagement Lösungen und beschleunigen zusätzlich den Änderungsbedarf. Der Vortrag beleuchtet, welche Aspekte bei der Modernisierung fachlich, technisch und organisatorisch zu berücksichtigen sind, welche Zielkonflikte zu managen sind und welche Potentiale sich für weitere Nutzung ergeben.
