contestations do not only originate with citizens, but also with city council
political preferences are encoded in business rules 
IT systems are not revised once a new government is installed
in theory, functional management, (or product ownership in a devops environment) is about periodically revising systems 
ombudsman can be a mechanism for identifying flaws
systems should be reviewed in light of changing context (political, legal)
when more than a few citizens complain one should ask if there is an underlying cause
citizens who do complain and have a decision revised don't know if the underlying cause has been fixed
distinction between ``purchasing'' and granting orders (subsidies) to third parties (e.g. foundations) for achieving a policy aim
    former: city is in control (purchasing conditions) -- but requires strong role as commissioner (``opdrachtgeverschap'')
    latter: no control -- but city could/should attach conditions about how they use AI/ICT
a final role is that city is complete owner (in-house)
in all cases city is responsible for implementation of the law (policy owner)
