The Rugby Football Union (RFU) should develop a national performance centre that will be operational by 2016, a review into England's elite structure has recommended.
'Strong values'
Keen, the architect of Great Britain's Olympic success from his time as performance director at UK Sport, said: "My task was to apply the same analysis to England Rugby as I have to other sports striving to be the very best in the world.
"What I found compared favourably with some of the very best practice I have observed in elite sport. I have been impressed by the quality of the people, their thinking and their actions.
"I have also been struck by the strong values and culture of rugby. Although areas for change and improvement have been identified, these align well with the momentum already building towards the 2015 World Cup.
"England rugby needs accelerated evolution, not revolution."
McGeechan stressed the need for co-operation between the RFU and clubs, adding: "The strength of relationships between the clubs and the RFU is paramount for the professional game in England to develop fully.
"We have spent many months talking to a wide variety of people on this very subject, and it is clear that great strides have been taken in this area, particularly with the coaches.
"The collaborative relationships must continue to be strengthened for the good of the game, so that everyone benefits.
"This integrated approach, across every facet of performance, will create a thriving base of professional players. From this base a strong club game, and even stronger international game, will continue to evolve so all the game's inherent potential is realised."
