You can minimize failure if the point of a system is not output but process. If you continually improve each individual process rather than just optimize for output. So for example in this case if we asked her parents not to produce a good child but simply to figure out how she can get to bed on time every night, then we are asking them to do an easily focused on thing. Do not tell them what to do, just say, "how can you do [x]?" maybe providing access to internet research capacities would be helpful for the parent, but in general simply getting them to focus on how to improve their immediate surroundings in that moment itself produces meaningful change.
