Approaching its 50th grand prix, Marussia continues to be one of the smallest teams on the grid, but Symonds is confident that it now has the set-up and know-how to move forward.
"It's really only a year since [the team] has become my major 'pre-occupation'. In that time, we've been trying to build the team up month by month as we go along. We wanted to achieve steady progress in terms of growth, but what I think is more important than the expansion is the improvement in the organisation, bringing everything under one roof and really building ourselves up into a credible team. We have been putting the team in a position where we can move up the grid over the course of the next few years.
"I think our  season has been one of continual improvement. We can certainly say that the start of the season was very difficult for us and, from that, we have experienced a lot of new heights - getting our wind tunnel programme working, delivering performance to the car in a cost-effective way, improving our procedures. It is important to remember that we're a very new team, and therefore there is an awful lot to be addressed. But I think rather than a single highlight there is just a continual improvement - a slow march forward towards the leaders and our direct competitors. Those are the things that give us some confidence in where we are heading."
