An interesting question your piece raises is how to identify when litigation is an appropriate tactic as part broader political engagement over socio-economic rights. Of course there will be no one-size-fits-all answers, merely general guiding principles.

I would argue that Equal Education, a South African education rights NGO, is getting it right with its current litigation and campaigning for norms and standards for school infrastructure: http://www.equaleducation.org.za/overview/minimum_norms_standards. It would be interesting to hear from readers about similar examples in other countries.
