Redfearn is desperately on the hunt for players as he bids to resurrect the Millers' season, but will only bring in players who he feels will improve the side.
The former Leeds boss believes he has inherited an "imbalanced" squad from Steve Evans, who brought in close to 90 players in his three and a half years at the club.
"The three or four that might come in for us to look at would, I think, give us that little bit more quality and that little bit more experience," Redfearn, who goes head-to-head with Evans on Saturday, said.
"So when we do have our youth and legs in there, there’s a balance. And I think this is what I’ve got to try to put in place, because, as I’ve said before, when I look at the squad it’s imbalanced.
"It’s just been players brought in as and when. There probably needed to be more thought behind it. We can’t go through that again.
"I think that’s what’s been overwhelming from the technical board meetings that we’ve had and the thing we’ve all agreed on. The way forward is that we’ve got to plan better and we’ve got to structure better."
Redfearn has also said he wanted to reduce the average age of the squad, something he has already done in his short time at the helm.
Although he has added Leon Best to his squad and continues to run the rule over experienced out-of-contract players Stephen Hunt and Stephen Kelly, the two signings he has actually made have been Harry Toffolo and Brandon Barker, who are 20 and 19 respectively.
And Redfearn hopes his pedigree at Leeds, where he brought through a raft of young talent, could persuade clubs to send their best prospects to New York Stadium.
"I think that’s the thing clubs will look at," he added. "I put a lot of the kids in at Leeds and they thrived.
"With my background being in that area, I know a lot of the kids are the circuit already. I’ve come across them. It’s been easy for me to identify them.
But it’s getting the right ones in. And, once you get the right ones in, give them their head. It’ about getting the right balance."
