Thank you for the opportunity to help you with your question!
The functionalist perspective says all parts of society are interrelated and dependent on each other. So for instance, if the education system failed it would cause failures of other systems in that society until the other systems adapt or change order.
In short your answer would be- the failure of one institution would cause the failure of other institutions until the others adapted.
