Gatland admits there will be no instant miracle cure to victory as his national team now mirrors the results of the four regions and the Under-20s with players suffering more defeats than victories.
“The sad thing at the moment is that we're probably a reflection of what Welsh rugby looks like,” said Gatland of the Wales men's national team.
“Maybe we were in an anomaly in the past, where we weren't, and we were able to control that or get out of what was happening behind us.
“So people are aware of the changes that need to be made to hopefully improve Welsh rugby in the future.
“It won't happen overnight, it will take some time.”
Gatland accepts that the review was wide-ranging.
“It was very comprehensive, not just looking at the team but looking at the whole of Welsh rugby over the last 15 to 20 years,” Gatland said.
“The pathway system, the academies, the under-20 programme, all things like that. We've looked at things to put in place for the future.
“There was some criticism of things, which you would expect in any review. There were things we had to look at in terms of some changes we felt we could make moving forward.
“There are a number of things for us that won't make a difference in the short term but will make a difference in the long term.”
Gatland admits he has changed his approach to dealing with players over the years.
“I think you probably need to calm yourself down a little bit to where you've been in the past in terms of the language you may have used and how direct you may have been and perhaps how critical you may have been,” Gatland said.
“Sometimes you ask the question – are players today as flexible as they were, as resilient as they were before?
“I'm definitely aware, and not just me, but all the coaches are aware of the way we talk to players and the language we use in terms of maybe not undermining their confidence.
“So there will certainly likely be changes with the players in regards to that.”
