Dynamic capabilities are central to firms' strategic decision-making and have received increasing attention in recent years due, in part, to the development of the information society. This research explores how web-based and human information sources interact and advance the development of dynamic capabilities. We use a mixed-methods approach executed in two studies. Study 1 reports insights gleaned from in-depth interviews with 12 senior managers. Study 2 provides the findings from a survey completed by 139 senior managers. The analysis indicates that the use of web-based and human information sources facilitates all dynamic capabilities types – sensing, seizing, and reconfiguring. Furthermore, sensing mediates the effects of the information sources on seizing and reconfiguring. This research highlights the strategic potential of using business information sources to advance dynamic capabilities while differentiating between the most commonly used information sources and inspecting their individual and synergistic effects on the advancement of dynamic capabilities.
