England are tapping into the success of Team GB in their quest to supplant New Zealand as the game's dominant force.
Eddie Jones and his coaching staff are to spend time with their counterparts in hockey, judo and cycling over the coming weeks to learn from the methods that helped underpin the gold rush at Rio 2016.
Team GB finished second on the table after winning a record 67 medals, two more than they managed in London four years earlier.
Among the stars were the women's hockey team - guided by head coach Danny Kerry - who defeated Holland in a penalty shoot-out to top the podium against the odds.
England have secured a Grand Slam and completed a 3-0 series whitewash of Australia since Jones took charge last December but the 56-year-old knows that to overhaul the All Blacks they must improve further.
"We've got to get better. We haven't done anything yet. We're not number one in the world, so we still have a lot to aspire to," Jones said.
"We've been working really hard with our coaching staff on how we can coach better because we didn't coach well enough on tour.
"Although we're happy with the results, we're not happy with our performance on tour.
"We need to coach better so our coaching staff has been working very hard investigating other sports.
"With Great Britain doing so well at the Olympics, there are a number of sports to look at and learn from. People have come in and talked to the staff.
"We've got Danny Kerry coming in in a week or so. Look at what he's done with his hockey side.
"If you look on face value at the talent in that team compared to the Holland team, it's probably not as great ... his ability to create such a dynamic and hard working team is fascinating, so we'll learn a lot from him.
"We're going to visit judo in a couple of weeks. We've had conversations with the cycling.
"Our motivation is just to get better. We want to be the number one team in the world. New Zealand are head of the pack at the moment but they're beatable, they have flaws in their game."
