Manager Paolo Di Canio has been allowed to sign 11 players so far this summer and is hoping to boost his squad further by the time the transfer window closes next Monday.
However, with director of football Roberto De Fanti and chief scout Valentino Angeloni already scouring the globe for emerging talent, the Black Cats are ready to invest in youth and potential in the future.
Writing in her programme notes ahead of the Capital One Cup tie against MK Dons, Byrne said: "Our scouting team are already looking ahead to future seasons.
"They are monitoring players across the world, especially young prospects, and as a club our approach to recruitment has been brought to a new level.
"We do not expect to have future transfer windows quite as busy as this one, but we do expect to be constantly developing new players through our Academy and development squad.
"We understand the need for a blend of youth and experience, which you can see for example with the signings of Emanuele Giaccherini as an experienced full international, and a young up and coming player such as Charis Mavrias."
