Zu den täglichen Aufgaben gehören die Arbeit mit dem Team, die Teilnahme an Eskalationen und die Teilnahme an Vorfällen mit hoher Priorität. Das Team besteht aus 19 Mitarbeitern, die mit diesen neuen Technologien arbeiten. Da sich der Kunde in einem Transformationsprozess befindet, gibt es derzeit viele Herausforderungen, da das Team geschult werden muss, die neue Netzwerkstruktur und -topologie erlernt werden muss und darüber hinaus die Dienste für den Kunden ohne Probleme aufrechterhalten werden müssen.
