The assignment that was named "the long road back to the World Group" by new captain Leon Smith in Eastbourne three-and-a-half years ago reached its objective on Sunday in the beautiful Croatian coastal town of Umag.
With a Wimbledon champion and a great crop of world-class doubles players at his disposal, Smith could be forgiven for thinking ahead and wondering just exactly what might be possible in the coming years for Great Britain's Davis Cup Team.
Perhaps the biggest surprise about the weekend's tie was the lack of hostility, normally associated with away matches, that the Brits had to face. In years gone by, coming to Croatia for a Davis Cup match would have been a living nightmare but as it turned out, Umag proved to be a place that many would consider returning to for a holiday.
The locals only really got behind their team in the third set of Saturday's doubles match and literally the last point of Sunday's fourth singles rubber between Andy Murray and Ivan Dodig.
Without star player Marin Cilic the Croats lacked any sort of belief and as a result Great Britain cruised back into the World Group for the first time since 2008.
As many predicted, much of the weekend could have been renamed the Andy Murray show. As is so often the case with Davis Cup ties, Saturday's doubles rubber is absolutely pivotal in the outcome of the tie and this was no exception. In Colin Fleming, Andy Murray had the perfect partner for the occasion.
Murray was so at ease sharing the responsibility with his childhood friend. Fleming has a magnificent Davis Cup record but in terms of a performance, Saturday was perhaps his finest hour in the competition to date. For two-and-a-half sets he was locked in on his returns, razor sharp at the net and always in the right place at the right time to dispose of any scraps left by the flailing rackets of the Croats.
Fleming also provided the perfect balance of focus and energy which allowed Murray to stamp his class on the match from the first point.
On Wednesday the draw for next year's World Group will take place in London and GB captain Smith has been invited to take part in the draw, perhaps a compliment on the back of his achievements over the last three years.
As is the case for any team, the dreaded draw is an away tie against the mighty Spain. However a Great Britain team including Murray, an improving Dan Evans and an excellent doubles pairing will be a match for any nation in the world.
For this team the job is to cement their place in the World Group and keep their rightful place among the world's elite.
