"It's all about the people. RubiKon's a great services business so it is all about the people," Barbsy told Defence Connect on the sidelines of the Avalon Airshow.
"I've been acquired myself, I was a part owner in a small defence business as well, so I've been through the process," he added. "It's early days but we've been putting a lot of work into how we take advantage of the best bits of both businesses."
Barsby said RubiKon would be able to contribute a greater customer focus and insight into how to service the customer and achieve really high-level satisfaction.
"We're working hard to make sure we pull that into the broader business," he said.
Barsby described how QinetiQ had kicked off a push to re-organise the firm to ensure it benefits from the know-how of the senior people in the RubiKon business.
"[We’ll] have them in appropriate senior roles within the broader business providing some opportunity for them straight away but [will] also ensure that, I guess, RubiKon has a voice within the broader structure," he said.
"We are a global business so there's all the opportunity that kind of mature business brings, the opportunities for promotion, advancement, training, working around the world."
