Beschreibung:
Businesses now have the ability to select specific applications from a wide range of communication and collaboration tools to deploy them for business-related tasks. To understand the ever-increasing number of offerings, companies are starting to leave the choice of communication and collaboration tools used to their own employees. The extent to which this freedom affects the decision-making of employees, however, has hardly been explored. Classical adoption models of business informatics so far consider the selection process solely from a 1:1 point of view, within which the evaluation process between the individual and the application is considered. In this consideration, however, the existence of alternative applications is neglected. This work therefore investigates so-called "multidimensional" evaluation processes, within which the user is aware of the presence of alternative applications. Based on the "technological-personal-environmental framework" of Jiang, Chen and Lai (2010), this multi-dimensional process is considered from a total of three perspectives within this cumulative dissertation. The results indicate that the existence of alternative applications has an impact on perception of currently used systems. Moreover, the results show that new applications are not evaluated in isolation, but in the context of already existing systems.
