Sauber boss Monisha Kaltenborn says her Formula 1 team needs to be more courageous if it wants to avoid this season becoming the worst in its history.
The Swiss squad has yet to register a point in 11 races this year, its longest scoring drought in F1.
If the team fails to score over the final eight grands prix it will be Sauber's first season without a point since it entered the sport in 1993.
Kaltenborn has already declared Sauber's current 10th place in the constructors' standings "unacceptable" and she has called for a more aggressive approach from her team to turn its fortunes around.
"In the development we did, maybe we have to change certain ways of thinking and get more aggressive," Kaltenborn told AUTOSPORT.
"Maybe [we need to] have more courage to go in different ways.
"I think there is potential in this car, which we have to unlock by understanding the data better, and understanding our car.
"We clearly have the tools, we have to work on our resources and when that's in place we need more courage to go out and do something else."
MORE TECHNICAL HELP NEEDED
Kaltenborn suggested Sauber had also been caught out by trying to produce too many of its own components and not making more of its technical partnership with Ferrari.
"I think what's different here that maybe puts us more into a role that Williams has historically seen, is that we've always done a lot of things on our own," Kaltenborn explained.
"We don't depend that much on working together with other teams; we do things ourselves.
"And this time we've not taken the right way.
"That's where we have to maybe change our ways of thinking more, because they are historical.
"Maybe with all of the demands and complexities on the car it can make sense to, here and there, co-operate with another team.
"But that's not the most important thing. In our own thinking we have to get more aggressive, towards our car and development.
"That's where we need to have a bit more courage."
