Ill. Im Buchh.: Berlin : Pro Business Dissertation Universität St. Gallen 2010 3685 Literaturverz. Aufgrund der wachsenden Nachfrage von Software-as-a-Service Lösungen, wie z.B. Salesforce.com, NetSuite, Taleo oder RightNow Technologies, stehen Unternehmen zunehmend vor der Herausforderung In-House mit SaaS Lösungen zu vergleichen. Die in dieser Dissertation vorgestellte Methode ‘IT Service-orientierte Investitionsanalyse' bietet eine gesamthafte und systematische Vorgehensweise, wie Entscheidungen zwischen den beiden Lösungsvarianten getroffen werden können. Die Methode berücksichtigt dabei sowohl die Sicht des Kunden als auch des internen IT Dienstleisters. Auf hohem Detaillierungsgrad werden in der Methode die Absatzprognosen und Verkaufspläne individueller IT Services, sowie initiale und geplante Kapazitäten von IT Ressourcen und Personal miteinander verglichen und bewertet. Die Methode baut auf dem am Institut für Informationsmanagement entwickelten Modell des industrialisierten Informationsmanagements auf und erweitert dieses durch für obige Analyse relevante Operations Research Konzepte sowie Controlling Verfahren. In recent years, the application of Software-as-a-Service (SaaS) solutions, such as Salesforce. com, NetSuite, Taleo, or RightNow Technologies, has increased significantly due to improved software functionality, more reliable service levels, as well as customers' pressure to cut IT costs. Since the beginnings in the late 1990s, SaaS - at that time still called Application Service Provision (ASP) - has changed from a simple outsourcing solution exclusively designed to meet small-and medium sized enterprises' needs, to an outsourcing solution that is able to support large enterprises' complex business processes. Consequently, when these days a company considers introducing a new IT solution, the conventional in-house deployment of packaged enterprise software must compete more often with Software-as-a-Service. However, a lot of tradeoffs need to be considered and decisions between these two IT solutions are rather complex requiring sophisticated investment analysis approaches. Thus, the method 'IT service-oriented investment analysis' introduced in this dissertation aims at providing guidelines for the ambiguous decisions to pursue in-house versus SaaS deployment solutions. Constantly changing customer requirements affect the efficiency of these deployment solutions and need to be taken into account. Thus, it is necessary to understand the relationships between changed requirements and implemented IT solutions on a detailed level. Based on this understanding, scenarios can be developed and based on probabilistic assumptions sound decisions can be derived. Striving for a holistic approach and considering the necessity of high granularity, the proposed method analyses each solution based on the level of individual IT services. For both IT solutions, it considers the view of the customer and the internal IT service provider, the sales forecast and projected sales plan of IT service units, the initial availability and planned utilizat...
