Telenet - a leading Belgian TelCo provider - adopted an scaled agile operating model across both Business and IT in 2019. Since then, the company has been on an intense learning journey, inspecting and adapting many elements of the original model. This talk reflects the stages of that journey. In particular, we shed light on the systemic elements that were hampering business agility. Addressing these required a paradigm shift for our leadership. In doing so we hope to demystify (at least a little) what an agile transformation entails.
