This study examines the impact of environmental uncertainty and integrative strategy on growth of firm performance through the mediating role of the Business Model Transformation (BMT) strategy of information communication technology (ICT) in Indonesia. The research data was collected from the executive management of ICT through survey research with 30 questionnaire surveys and exploratory study with seven company leaders through in-depth interviews. This study analyzes the suitability of the overall model through causal relationships using Partial Least Square-Path Modeling (PLS-PM). The results show that the BMT predominantly influences the growth of ICT companies. The BMT is predominantly built by the environmental uncertainty (ET) strategy rather than by integrative capability. Thus, companies need to improve their ability and creativity to anticipate and adapt to any uncertainty that unexpectedly results in dynamic competition.
