Fry started working at Williams in November after leaving a similar role at Alpine earlier this year, as a key figure in overhauling the team after years of underinvestment.
The former Benetton, Ferrari and McLaren man has been tasked with identifying and providing what each technical department at Grove needs for long-term success.
Fry started too late to have a drastic impact on Williams' launch car for the 2024 season, but Vowles believes that while Fry's focus is on longer-term strategy, he will soon prove valuable as the team boss tries to steer the squad into a new direction.
"I joined at a point this year where we could still have an impact on the car, but next year is really the sort of putting together of minds as to how we completely shift direction. And I'm actually really looking forward to how that turns out in four or five months' time," Vowles said.
"More so I've got Pat alongside me now. He knows how to do this, he's revered up and down the lane, ask anyone near enough and you've got a good chap in Pat.
"You're not going to change your chassis, but with the direction of travel we are in there are still things we can tune before we get to Bahrain."
