Information Technology (IT) leaders who do not invest in big data projects may struggle to gain a competitive advantage and business insights to improve performance. Grounded in the Kotter’s change and Six Sigma models, the purpose of this qualitative multiple case study was to explore strategies IT leaders used to implement big data analytics successfully. The participants comprised 4 IT leaders from 2 telecommunication organizations in the United States of America, who effectively used strategies to promote and maximize competitive advantage using big data analytics. Data were collected from semistructured interviews, company documents, and project-related documents and were analyzed using thematic analysis. Four themes emerged: communication, training, employee involvement in decisions, and teamwork strategy. A key recommendation emerging from these findings is for IT leaders to use successful communication strategies to communicate the vision and objectives effectively to all the different levels within the organization. The successful communication of strategy can help with the analysis of business trends and forecasts and improve overall organizational performance and competitive advantage. The implications for positive social change include the potential for job creation, thus catalyzing economic growth within communities.
