But in the second race in Malaysia and in Bahrain last weekend, Ferrari encountered problems and made mistakes when reacting to them.
Alonso could still have finished third in Bahrain and at least fifth in Malaysia. Instead, he crashed out in Malaysia and was eighth in Bahrain, missing out on a possible 28 points.
In Malaysia, he damaged his front wing
on the back of Vettel's car during lap one but Ferrari did not order him to pit immediately to have it changed. The wing subsequently broke at the start of the second lap, pitching Alonso off the track and out of the race.
In Bahrain, Alonso's DRS overtaking aid failed, leaving the top part of his rear wing stuck in the 'open' position.
He pitted to have it forced back into place but Ferrari allowed him to use it again when he returned to the track. It immediately stuck open again and he had to pit at the end of that lap to have it repaired for a second time.
Bahrain GP highlights: Sebastian Vettel powers to win
Ferrari said the problem that caused Alonso's DRS failure was "the breakage of a mechanical component within the system", the first time such a problem had occurred since DRS was introduced in 2011.
Ferrari have become renowned for their excellent reliability over the last decade and more.
Domenicali said it was crucial they did not let those standards slip.
"We must work with renewed attention on this front," he said. "In these first four races of the season, we have not managed, for various reasons, to bring home the points that were within our grasp.
"But we must not be discouraged by this. Quite the contrary, because we have seen so often, both in our favour and against, how things can change in a hurry."
