Alpine started the season in Bahrain with the slowest car on the grid after finishing the 2023 season in sixth place.
The Enstone squad soon realised in the simulator that its concept change for 2024 would be a sideways step at first, requiring further upgrades to regain competitiveness.
In the meantime Alpine staff turnover continues as Harman and head of aerodynamics Dirk de Beer both resigned from their positions.
In their place, Alpine announced a three-pronged leadership structure for its revamped technical team.
Despite the short-term pain, Gasly has faith that the changes team boss Bruno Famin is making will pay off on the long-term, although Harman's resignation came as a surprise to him.
"It's always a surprise because I've been quite close to Matt, coming inside the team, trying to understand a bit the philosophy, understand the changes, we've made on this new car;" Gasly said.
"So, obviously, it comes as a bit of a surprise. I obviously knew it slightly before.
"At the end of the day, I'd rather focus on my business. I'm going to drive the car fast and push the team forward and give them clear feedback. And that's where my energy goes into."
