Companies which create mobile business solutions require users to adopt them in order to create value for the organization. However, when mobile devices enter the workplace, companies themselves face an adoption process, in having to integrate these devices into the existing IT infrastructure. In this research project, we conducted a focus group with subsequent expert interviews, following a grounded theory approach. We identified seven drivers of mobile business solution adoption in an organizational context: mobile user experience, social influence, time to market, security, workplace flexibility, information availability and process mobilization. While these factors facilitate adoption for some users, they create challenges for or require strategic decisions from other organizational stakeholders, such as internal users, operating departments and corporate IT. The adoption factors and implications for organizational stakeholders were compiled in a conceptual framework.
