Driven by environmental uncertainty, many organizations today attempt to achieve agility at scale. However, given the variety and complexity of these efforts, there is currently a limited understanding in terms of their most relevant configurations, especially over the process of change. Based on an iterative taxonomy development approach grounded in design science, we present a taxonomy to structure, configure, and update scaling agility. The resulting multi-dimensional classification system offers an integrative view on elements only selectively considered in prior research. While offering a conceptual anchor for further research, we also provide specific configurations covering three different stages of scaling agility.
