There are many difficulties in agile transformations, and a majority of the transformation efforts fail. However, companies continue to pursue the agile path, pushed by forces, both in their environments and internally. The purpose of this study is to explore what facilitators and inhibitors are present in an agile transformation. This is to try and understand agile transformations better, and a lens of change management and culture will be utilized to focus on some essential aspects. To succeed in this, two research questions are to be answered: How does culture facilitate or inhibit change in agile transformations in a software organization in the automotive industry? And, how does change management facilitate or inhibit change in agile transformations in a software organization in the automotive industry? This thesis is a case study on a software organization in the automotive industry, and provides a retrospect on the transformation. The firm originates from the automotive industry, resulting in the industry-related culture to continue affecting the firm today, both internally and externally. To understand the organizational context, the history of the organization, and the culture, the case study try to go in depth by exploring solely a single case. The thesis results are that multiple facilitators and inhibitors are identified for each of the aspects. However, most facilitators and inhibitors relates to both change management and culture, touching upon the interplay between these aspects. Further, the transformation effort is identified to be dependent on both the organizational culture and the organizational context, implicating that transformations efforts are rather unique.
