Jevans helped deliver a successful 2012 Games and has been turned to for the 2015 World Cup, which will be hosted by England, although several matches will also played at Millennium Stadium in Wales.
While Jevans believes the tournament is on a smaller scale, she warned organisers against becoming complacent.
"If you deliver a major sporting event, be it for one sport or 26 sports like we had at the Olympics, you still need hotel rooms, you still need arrivals and departures sorted, you still need transportation, you still need have your catering right," Jevans said.
"The complexity is exactly the same as the Olympics, it's just a smaller scale.
"But that doesn't mean it's any easier, it doesn't mean we are in any way more complacent to make sure we deliver it, but the scale is clearly different to the Olympics."
Wednesday marked two years until the start of the World Cup with the first match of the tournament to be played at Twickenham on September 18, 2015.
Tournament ambassador Lawrence Dallaglio, who played in England's successful 2003 campaign in Australia, said hosting the event was a huge opportunity for the country.
"It was a fantastic experience, winning a World Cup in Australia," the ex-England flanker said.
"This is quite a unique experience for all of us because England will be hosting the World Cup for the first time on its own, with some games down in the Wales' Millennium Stadium.
"It is about creating memories, it is about creating dreams. It really got me thinking about rugby and sport very differently."
