"Probably Eddie's biggest selling point was that England has never won a series in South Africa. For me that was a bit of a challenge," Wisemantel told British media.
"It's a Cinderella story if we do it. I wouldn't have come here if I didn't believe England have the players to win there and that I can make an improvement."
England are keen to put more emphasis on attacking play after a poor Six Nations campaign during which they lost their last three matches to finish fifth.
Wisemantel has a reputation for having the courage of his convictions and said he would not hesitate to stand up to Jones with regard to tactics during the tour.
"It is not easy but that's a real relationship, isn't it? If I disagree, I disagree and then we have the debate and vice versa," he said.
"The quality (of the team) in general is good but is it perfect? No it's not. So we're going to aim for perfection," he added.
"The reality is, in an open-skill sport when you've got multiple decisions, you're never going to get perfect but their desire to get better is probably one of the qualities that has stood out."
England face South Africa in Johannesburg (June 9), Bloemfontein (June 16) and Cape Town (June 23).
