The agreement to let Micheal Martin have the first stint in the Department of the Taoiseach was agreed some time ago.
The argument from Mr Martin's side was simple - Fianna Fail won more seats, albeit marginally, than Fine Gael.
His team also insisted he was entitled to the first term in the rotation deal because he was the only political leader seeking to form a government after the election.
They also said he represented a form of change, or at the very least he is not a Fine Gael leader.
Going first has its benefits - and its drawbacks.
Over the coming years, the Government is planning to borrow heavily from the international markets and pump the money into major infrastructure projects.
If you are willing to get your hands dirty, there should be a job or at least an apprentice scheme available to you.
Houses will be popping up all over the place, along with new roads, cycleways and pedestrian footpaths.
Although he regularly scoffed at Fine Gael for its ribbon-cutting photos, Mr Martin will now be happy to show up in his hard hat and hi-vis vest to launch new developments.
If he is leading it or not, Fianna Fail is going into the next election as a junior partner in Government, no matter how many seats it holds.
Leo Varadkar is not happy with being demoted from office after serving three years as Taoiseach, but his team believes it is the best option for the party.
The job of governing may become more difficult in the second half of the Government's term when it tries to reduce the massive deficit created after years of borrowing.
However, the main benefit for Fine Gael going into the next vote will be the fact that it holds the Taoiseach's Office.
The new government is a partnership of equals between Fianna Fail and Fine Gael, with everything divided up equally.
There is no getting away from the fact that the Taoiseach's Office is where power lives, and it is a major benefit to hold the office.
However, there is a risk that once Mr Martin leaves office, Fianna Fail TDs will be less obliged to prop up Mr Varadkar and Fine Gael.
Some have even begun talking about "causing a row" and forcing an election in early 2023, but then again they might all get along famously.
