This research investigates agile transformation using empirical case studies of three publiclyfunded organisations. Our findings focus on tensions that arise during organisational transformations and are based on authentic accounts and concrete experiences. Practical insights for those leading agile transformations that emerge from this work are: A transformation to organisational agility may start from a range of different foci, including culture change, strategy change and operational change. Our accounts provide insights into the complexity and variable nature of organisation-wide transformations. Quoting one Head of Transformation: "I thought we'd embarked on achieving a destination, but actually what we embarked on was a really long journey" Multiple tensions of different types will arise throughout the transformation. We identified 13 tensions from the three case studies. This is not an exhaustive list, but it illustrates the kinds of tension organisations face in agile transformations. We show that viewing tensions through the lens of paradox theory supports transformation leaders and managers to elucidate the tensions their organisations face. We provide specific questions for leaders and managers to ask before and during transformation, to help navigate tensions that can occur in transforming to agility.
