The right blocks were in place to achieve that and he believed the side had retained sufficient intellectual knowledge in place from the winning side.
"Rassie [Erasmus] did galvanise his coaching staff in a way that everyone understood their roles and responsibilities in taking the team forward," Habana told a school awards ceremony in South Africa.
"You'd hope that the powers that be who'll be making the coaching decision make one that's for the good of the game."
Habana said he couldn't remember any of Erasmus' management team having been head coaches before but he was confident the right decision could be made with Erasmus taking over as director of South African rugby.
"It's far different from when Jake White won the Rugby World Cup and was let go [in 2007]," he said.
"There's been reruns of losing critical knowledge but with Rassie in charge, the knowledge is there and whoever moves in can pick up where Rassie has left off."
The decision was vital this time around as the Springboks have to gear up for a tour by the British & Irish Lions in 2021.
"Every time the Lions have been in South Africa in the professional era, we've been world champions.
"With SA again world champs, it adds an extra element and Warren Gatland wants to become the first British & Irish Lions coach not to have lost a series, having drawn against New Zealand and beaten Australia," he said.
"Whoever is coach and captain of the Boks leading into that series will know we're the holders and won't want to lose."
Northern hemisphere teams had shown a lot of power in the World Cup as compared to the 2015 World Cup and England had been deserving finalists, he said.
"It adds to the spice of the series, but there's a lot of water that needs to go under the bridge before 2021," he said.
Habana believes South Africa would be well placed to deal with the Lions' threat.
"This Bok group has been exceptional, it's different and with what they've achieved, they'll be able to move forward to the 2021 series with a strong core of players.
"There's some phenomenal players that have committed to SA Rugby which is great because I hope that'll form the backbone of the team that could be comparable to the 2007 Cup-winning team that went on to have an exceptional 2009.
"It created a strong succession plan and that is something Rassie has in place for the players who are going overseas. These players, though, have created their own legacy," he said.
