This proposed research aims to explore how institutionalization of Business Intelligence (BI) can enhance organizational agility in developing countries. Business performance is increasingly affected by unanticipated emerging opportunities or threats from constant diverse changes occurring within the environment. Decision-making to cope with the changing environment becomes a challenge for taking opportunities or managing threats. Organizational agility is the ability of sensing and taking opportunities through responding to those changes with speed. As BI provides data-driven decision-making support, BI institutionalization is vital for enhancing organizational agility to make a decision for responding to the dynamic environment. However, there has been little prior research in this area focussed on developing countries. Therefore, this research addresses the research gap in how BI institutionalization in developing countries can enhance organizational agility. Bangladesh is used as an example of a developing country. A multiple case study approach was employed for collecting qualitative data using open-ended interviews. The studied data were analysed to generate new understanding of how BI institutionalization impacts organizational agility for decision-making in the context of developing countries.
