Im nachfolgenden wird ein komprimierter Überblick über mögliche Public Cloud-CRM-Lösungen am Markt aufgezeigt. Prinzipiell existieren auf Basis unserer Erfahrung zwei grundlegende Möglichkeiten.
Basierend auf den Einflussfaktoren zur Nutzung von Public Cloud CRM (vgl. Kap. 4) muss eine Entscheidung getroffen werden, ob eine CRM in der Public Cloud im Unternehmen eingeführt werden soll.
Public Cloud-Lösungen wie CRM werden für Unternehmen immer wichtiger. Für viele Unternehmen kann dies ein richtiger Weg sein, um die Bereitstellung eines guten CRM-Instrumentariums zu gewährleisten. Die Entscheidung für diese Lösung ist jedoch mit vielen Fragen verbunden, welche im Einzelfall und unter Abwägung vieler Gesichtspunkte geschehen muss.
Cloud-Computing ist ein Ansatz, der darauf fokussiert, die Arbeitsteiligkeit im IT-Bereich zu erhöhen [5]. Im Gegensatz zu früheren Ansätzen setzt Cloud-Computing stark auf die Automatisierung von Dienstleistungen und ist sehr stark technologiegetrieben [48].
Customer-Relationship-Managementsysteme in der Cloud können entweder durch das Unternehmen selbst betrieben werden oder bspw. über einen externen Anbieter in der Public Cloud realisiert werden.
Dieses essential stellt fundiert und praxisorientiert die Grundlagen von CRM in der Public Cloud dar. Das Autoren-Team gibt einen grundlegenden Einblick in das Cloud-Computing basierte Customer Relation Management und zeigt auf, welche Faktoren die Kombination der beiden beeinflussen. Sie erfahren, wie ein Public-Cloud-CRM-System eingeführt werden...
