"We have very good people," Perez told Motorsport.com this week. "There are no politics in the team so people are allowed to do their job.
"It makes a massive difference in the environment of the team. Everyone is working to be better as a team and that is a key to it."
Perez added that while other teams might have bigger budgets which were "a nice thing to have", such extensive resources came with a price and could also work against a team.
"It is important to have a good structure with good people and we have very key people in each role, who do their job properly.
"That makes a massive difference in the team, having good team bosses."
As proof, Perez pointed to Force India's impressive form in 2016. After a sluggish start to the season the team has picked up 95 points in the last nine races and clinched podiums in Monaco and Baku.
Force India are currently in fifth place in the constructors championship, just three points behind Williams. Perez himself is in eighth place in the driver standings, one spot ahead of his team mate Nico Hulkenberg.
Perez explained that identifying the issues with the VJM09 that were contributing to tyre degradation problems was the mean factor in helping Force India get stronger over the course of the season.
"We knew we had a competitive car," he said. "We focused so much on weak areas of the car early in the year and that has helped us massively."
After speculation that he could replace Felipe Massa at Williams, Perez is now expected to stay with the team in 2017, although no formal announcement has yet been made.
