The organization are indeed decades old. Some of them indirectly and lately participated to the revolution in 2010 that brought down the President-Dictator and triggered the so called Arab Spring. They were "infiltrated" by the former regime by the way and a huge power fight happened within those organizations because of that. Nobel Prize is not however given to them for their struggle back than, but for the period 2013-2014 where Tunisia was already well after the Arab Spring, elected a Constituent Assembly (one that was supposed to write a new Constitution and organize a new election). It was a unstable period in which two political assassination were committed against anti-Islamist MP, public opinion was heavily divided between supporter of the coalition in power led by the Islamist Party and the opponent led by nationalist and lefties. That is when the Quartet played a major role bringing all parties together into the negotiation table and imposed a "technocratic" government. The Military coup against Morsy in Egypt helped in that regards immensely to be honest as the Islamist in Tunisia feared they ll have the same fate if they do not show more flexibility.
To be honest, what the Quartet did was crucial as Tunisia could have ended like Libya in a total anarchy or like Egypt back into ruthless dictatorship.
