Abstract

This dissertation project aims at developing a theory-based model that explains the influence of software product and service characteristics of Software-as-a-Service on the relation between organizational integration and the extent of a solution failure. The model is grounded on a thorough literature review of IS and non IS literature and exploratory case studies with different Software-as-a-Service vendors. Typical software service characteristics like simultaneity as well as typical software product characteristics like a multi-tenancy architecture have been identified within existing Software-as-a-Service solutions. The preliminary results propose that software product and service characteristics of Software-as-a-Service increase the importance of internal and external integration to prevent a Software-as-a-Service solution to fail. Software-as-a-Service solutions are argued to require software vendors to integrate internal activities like development and operations and external entities like customers much tighter in order to be successful.
