Maurizio Arrivabene has named the areas in which Kimi Raikkonen will be judged ahead of a decision on the Finn's future later in the year.
Raikkonen had his worst weekend of the season in Austria, qualifying 18th (which became 14th once grid penalties had been applied to others) and crashing out of the race after the second corner. He is now 48 points adrift of team-mate Sebastian Vettel in the standings and pressure is mounting as Ferrari decides whether to keep him at the team next year.
Arrivabene insists the Austrian Grand Prix weekend will not influence Raikkonen's future directly and a decision will instead be based on analysis of various different aspects.
"It's not a question of today or yesterday," Arrivabene said. "Of course we have a deadline [for a decision] and I'm not going to tell you when the deadline is. But it's an overall view that is about conducting our decision.
"I was talking about performance, performance means a holistic approach: how is the feeling with the engineer, how he's working with the engineer, how he's getting points, how he's getting podiums, how he's quick, how he's working out - many, many, many things. And now it's early to tell him something or to decide something.
"I could look a bit too much defensive or protective of him, but we are not even halfway through the season. Try to be in my position and to go to Kimi for example to say you are out or you are in or whatever. I want the best to be concentrated on what we are doing today and to give us the maximum."
Arrivabene said the ultimate decision will rest with Ferrari president Sergio Marchionne.
"I could suggest my point of view and then you need to talk to the president to take the final decision. In the normal world, the normal companies work like this. I mean if you are the president you can do whatever you want, if you are not you have to share your decision to get the approval."
