What is a value conflict, and which values most often conflict?
A situation in which a technology supports one value while undermining another; privacy, autonomy, security, well-being and inclusion are the values most often in conflict.
Example: a sensor-based system supports physiotherapy exercises at home. It promotes the patient's well-being, but can conflict with their autonomy, because it insists on the "ideal" way to do the treatment. Conflicts can also run between parties, for example a suspect's privacy against the well-being of society.
Translating values into software requirements is a relatively neglected step. One method for ranking conflicting values is a value hierarchy built by pairwise comparison: compare two values at a time and derive the overall order from the answers.
