In my projects, working hand in hand with the customer, since he is the owner of its processes, and acted only as a resource to resolve any incident or problem by offering my experience and showing the pros and cons of the solutions considered. Finally, I also offer the customer more information about the implemented solution, so that it can administer and manage it.
