The growing prevalence of AI systems in society, has also prompted a growth of AI systems in the public sector. There are however ethical concerns over the impact of AI on society and how this technology can impact public values. Previous works do not connect public values and the development of AI. To address this, a method is required to ensure that developers and public servants can signal possible ethical implications of an AI system and are assisted in creating systems that adhere to public values. Using the Research pathway model and Value Sensitive Design, we will develop a toolbox to assist in these challenges and gain insight into how public values can be embedded throughout the development of AI systems.
