Ted Kravitz Q&A: Analysing where Ross Brawn's exit leaves the Mercedes team

In the end, Mercedes' announcement on Thursday morning confirming Ross Brawn's exit at year's end came as a surprise to no-one. And yet the departure of one of F1's most prominent figures from one of the grid's biggest teams still provokes immense fascination.

Given Mercedes are targeting a World Championship assault with their new turbo engine next year - as Lewis Hamilton made clear to Sky Sports News this week - and Ross's title-winning credentials are proven numerous times over, how big a blow for them do you see his departure being?
TK: "I see it as one step forward and two steps back, unfortunately. I think you'd have to say that what you are gaining in Toto and Paddy and their clear talents is one step forward, but what you're losing with Ross is two steps back. I don't think there is any other way to see it. "You're going to need a strategic brain on the pitwall next year and if something goes wrong, you're also going to need the meticulous, calm approach and experience of a man who knows how to get you out of the hole that you're in. "Now, actually, it looks like, if we're to believe everything we hear out of Mercedes, that it's likely that things aren't going too wrong for them and that they've got a car that has spent longer in development than most and an engine and energy-recovery system package which is pretty mature in its development as well. "So maybe they'll get away with it because they'll have the best package, they'll be winning races and they'll be saying 'Who needs Ross?' Well, that's fine, but wait until the bad times or the times you don't want a computer to tell you what the strategy is, when you want a calm head on the pitwall. That's when they will miss him." How do you see the Wolff/Lowe 'dual Team Principal' arrangement working? That fact such a scenario is fairly unusual in F1 makes it something of a test case for the sport doesn't it?
TK: "The last time I remember having an arrangement like this was actually at the last team that Niki Lauda was in charge of and that was Jaguar. Then you had various people like Gunther Steiner, Dave Pitchforth, Richard Parry-Jones at the top, Bobby Rahal and Lauda himself all in charge of various bits of the company and it was a mess. That team folded effectively and it was sold to Red Bull for £1. "I don't know whether this is something Niki Lauda believes, that the job of Team Principal is too big for one person, but who's going to be making the decisions? That was Ross's point: you need to have one point of reference. It's a warning to the team that he's saying 'Okay, well you've chosen not to have one point of reference, I'm off, good luck with that!' "But it also reminds me of Nick Fry's role at that team. Ross was in charge of the racing side and actually people underestimated how much Fry did. Fry was in charge of running the company, doing all the boring things like budgets and HR and ordering in equipment and material, and also sorting out all the sponsorship as well. That's a big job. It worked with Nick Fry and Ross Brawn even though Fry was the race team MD effectively, a bit like the role Jonathan Neale has at McLaren. "Toto Wolff seems to be in a higher position than that. Is he going to be content with doing the negotiations to sort out who's going to supply the team with their carbon fibre or which company gets the deal to run the canteen at the factory? Is that what he's going to be doing?" And what of Paddy Lowe's role and responsibilities? At McLaren he was working quietly in the background the whole time, but going forward at Mercedes he's going to have a higher profile isn't he?
TK: "Paddy's never been a big paddock
