Formula One champion Fernando Alonso just signed up a 2-years contract with the french team Renault Sports, which he left at the end of 2006 to join the Brits of McLaren.
The 2007 season was kind of a disaster for Alonso, who couldn't become F1 World Champion for the third time in a row because of some conflict with his own teammate, the young Lewis Hamilton.
The question is : did Alonso lost a year at McLaren ? Did Renault lost a year too, not being in the top-3 teams this year ? Answer is : not at all. Fernando Alonso has had the unique chance to learn a lot about another team, another philosophy, another strategy. Renault Sports has had the opportunity to test different technical solutions to overcome its interim misfortune. Combining both experiences will bring both of them to the next level.
What's the point ? This : change the names for whoever you want in your own business, and you'll understand why sometimes companies let their best people go to the competition for a while and then bring them back home.
