Leading a several thousand people organization towards Agile is not an easy task. It is a complex challenge where there is a very low predictability of success of your change initiatives. In this talk I will give you some theoretical background on how to successfully approach change in your company. I will exemplify this with the story of our agile change at Ericsson, one of the world’s largest SW companies. I will talk about our change initiatives, the desired and undesired things that emerged from them and how we acted upon them. This will help you understand the nature of an organizational change towards Agile and how to successfully approach it yourself.
