Agile methods hold a significant promise to reduce cycle times and provide greater value to all key stakeholders involved in the software ecosystem. While these methods appear to be well suited for embedded systems development, their use has not become a widespread practice. In analyzing the state-of-the-art, as captured in published literature, we found that there are technical issues (requirements management, and testing), as well as organizational issues (process tailoring, knowledge sharing & transfer, culture change, and support infrastructure). In this paper, we build preliminary guidance for firms around these six areas and presented as a framework that will enable understanding the expected adoption trajectory.
