Information systems (IS), as a multi-disciplinary research area, emphasizes the complementary relationship between people, organizations, and technology and has evolved dramatically over the years. IS and the underlying Information Technology (IT) application and research play a crucial role in transforming the business world and research within the management domain. Consistent with this evolution and transformation, I develop a two-project dissertation on Information systems capabilities and organizational outcomes.

Project 1 examines the role of hospital operational effectiveness on the link between information systems capabilities and hospital performance. This project examines the cross-lagged effects on a sample of 217 hospitals measured over three years, to ascertain the effect of Hospital IS capability variants on Hospital performance in terms of quality of care and profitability, as mediated by hospital operational effectiveness. Hospital operational effectiveness was studied as process efficiency and service efficiency. The results of our study provide evidence for a considerable causal impact of hospital IS capabilities on hospital performance as mediated by hospital operational effectiveness.

Project 2 investigates the impact of CEO’s communication styles on organizational performance using text-mining approach on CEOs tweets from social media. The contribution of our study is three-folded: 1) From a methodological standpoint, we present a model to establish a relationship between CEO communication styles on social media and firm performance. Additionally, we apply text mining to identify communication styles of CEOs. 2) From a performance management, we evaluate organizational performance in three types: Operational, Financial, and Reputational. 3) From a management practice and policy perspective, our study results will help organizations evaluate the CEO candidates from a communication style standpoint.
