Paddy Lowe insists it's not a case of "too many cooks spoiling the broth" at Mercedes.
The former McLaren man moved to the Brackley-based squad as an executive director (technical) last month, joining the likes of Bob Bell, Aldo Costa, and Geoff Willis in the tech department.
There have been suggestions that Mercedes have too many technical experts on board and it could have a negative impact on their performances, but Lowe is having none of that.
"If people think that there are too many technical directors in Mercedes, then all you can say is that it seems to be working for them," he is quoted as saying by Autosport.
"Mercedes have made fantastic progress in the last 12 months, so what is wrong with that?
"The other thing is that it is not as though there are a whole bunch of cooks trying to do the same job.
"There is always a huge amount of work to do in this business if you want to be successful.
"Within two days of starting in my job here, I could already not find the hours in the day to do what I could see needed doing. That is how it should be, that is the nature of F1."
Lowe's arrival initially led to rumours that he will replace Ross Brawn as team principal, but it has since emerged that he is being earmarked as boss in the long term.
The 51-year-old insists the structure at Brackley is perfect at the moment and they have the structure to challenge for Championships.
"As I have come in there is certainly no need for a revolution," he said. "I think it is a great team. They have achieved fantastic progress over the past 12 months.
"It won the Championship [as Brawn GP] in 2009. And although there were special circumstances around that, you still cannot win championships if you don't have some strengths around how to build, run, manage the car and exploit it on track.
"You always say you cannot win races without a good driver and a good car; but you cannot win a Championship by miraculously producing a quick car.
"These things come with having all the right elements. That is all there."
