If there is one quality that Andy Cowell, Aston Martin's CEO and now Formula 1 team boss, has shown in the 100 days since he officially started, it is that he is not afraid to make the tough calls.
For while part of being successful in F1 is the fun aspect of hiring the best people, there is another side to it in being bold and not shying away from making changes if things are not working.
We got a first glimpse of Cowell's willingness to take action last year when technical director Dan Fallows was moved aside in the wake of the failure of the squad to make progress during 2024, and especially when its Austin upgrade did not work.
But ahead of the new season, Cowell has wasted no time in conducting a much deeper overhaul of an organisation that he clearly feels has not been operating in the way that he thinks it needs to.
His self-appointment as team principal, Mike Krack's switch to a chief trackside officer role, and a new reporting structure that separates the trackside and factory teams for aerodynamic plus engineering/performance, is all about addressing core weaknesses he saw.
In particular, it is understood that Cowell felt that there was an element of confusion between factory roles and those at the track - with people dragged too much into responsibilities for both.
This led to problems with distractions and communications, and some personnel spread perhaps too thinly across roles that should have been separated.
It is this desire to get people focused more on specific priorities that has triggered the move to get previous team boss Krack into his new position where he leads operations on the race weekends.
This will allow Krack to concentrate on the day-to-day engineering business at each grand prix, and only need to think about bigger picture team stuff at the races Cowell will not attend.
Cowell's desire is for things to be simplified and to have structures that are cleaner and not top heavy, which is why, with Krack's responsibilities changing, there is no need for the performance director position that Tom McCullough previously held.
As someone who earned a reputation for producing the most efficient engines in F1, Cowell clearly has a mindset of not liking wastage in any organisation.
Speaking shortly after his arrival at Aston Martin last year, he offered an interesting insight into how he thinks organisations should work.
"It makes me grumpy if there's overlap of responsibility," he said. "It makes me grumpier still if there's a gap and a lack of communication.
"How do we get 900 people to work efficiently so it's like one brain? Writing reports and having meetings...I'm not too keen on that sort of thing."
Cowell was clear that key to him was having a structure in place that is simple, clear and understood by everybody.
"My job is to create a team," he added. "And in a team everybody knows what their role is. They know their position on the pitch.
"My job is to discuss with each of those players what they could do to get better, not tell them.
"It's just to instil a high-performing atmosphere of doing something, learning from that experience and thinking of new ideas."
