Former England and British and Irish Lions coach Clive Woodward named George North among those who have come through the Welsh system.
The Welsh Rugby Union elite pathway structure has been singled out for praise by the former coach who masterminded England's Rugby World Cup victory.
Sir Clive Woodward says the focus on developing quality players has helped the senior national side select from strength.
He also pinpointed the establishment of a WRU National Centre of Excellence at the Vale Resort near Cardiff as a key factor.
Writing in the Sunday Times, Woodward said: "Wales realised the importance of quality, not quantity. They have, in partnership with the Vale of Glamorgan resort, established an outstanding centre of excellence.
"They have a highly experienced, settled administration and coaching team. Rob Howley, interim coach in Australia, proved they also have succession planning in hand. The physical condition and mindset of the Wales team have clearly changed for the better."
Woodward also supported his argument by naming key Wales players he says outline his argument.
He named George North, Alex Cuthbert and Sam Warburton who are all players developed through the age grade and 7's structures in Wales.
The former Engalnd coach was explaining his views on elite performance as a priority in player development for national teams.
