The Formula One team considered it too dangerous to continue without communication but Atlassian Williams trackside technology principal James Kent says the incident could have been prevented.
The fault behind the failure showed up earlier in wind tunnel tests but that information wasn't shared with the mechanical team.
"If we had this at the time, it would given us an edge or it would have prevented an occurrence at track," Mr Kent told AAP.
"I would have been able to get to a resolution that would have prevented us from stopping on track ... because of a lack of radio."
Tracking fault data is one reason the 49-year-old team sought technical help from major sponsor Atlassian.
It last year struck a deal with the Australian software company co-founded by billionaire Mike Cannon-Brookes, who also serves as its chief executive, for the 2025 season and beyond.
The race crew had been tracking mechanical issues across 28 separate documents, Mr Kent said, and keeping important information in a spreadsheet with millions of cells.
Using a central database and artificial intelligence agents to highlight vital information and prevent duplication was proving useful on and off the track, though its AI transition had just begun.
"Data is the most important thing to us within this sport - the quicker we can create, address, enrich, the quicker we're able to iterate," he said.
"When you look at what the trajectory Williams are on, we're still in a building phase so we're looking to make sure we collect as much information as we can."
Managing faults and streamlining tasks are major issues for any Formula One team, Atlassian customer chief technology officer Andrew Boyagi said, but will be a particular challenge after rule changes that come into force at the Melbourne event.
Changes to the race include smaller and lighter vehicles with less drag and downforce, a 50-50 split between internal combustion and electric power, and the use of sustainable fuels.
Using new vehicle designs will force all teams to adjust their strategies, Mr Boyagi said, and the groups which adjust quickest will benefit.
"This race, because it's the first one with new regulations, in some ways - and probably everyone at Williams will disagree with me - it doesn't really matter how you go in the first race," he said.
"It's how you improve over time that matters and fault management is really central to that.
"The teams that are the most successful in Formula One are the ones that continuously learn and improve the fastest."
