Alpine finished sixth in the 2023 constructors' championship after a mixed season that saw it log two podiums while struggling at some venues.
The team is investing heavily in new infrastructure, with a new simulator building on schedule to come online as the team ramps up the development of its 2026 car.
Helped by the extra spending capability other factory tools are also being upgraded, and Harman believes the changes will pay dividends in the short term.
"Our focus is very much on the future and the 2026 regulations as well as the cars that we need to do between now and then," he said.
"We've also got a big programme at both sites [Enstone and Viry] to improve the capabilities and the functions – you will have seen this in CapEx equalisation topics that have gone on with the FIA.
"We're fully funded to achieve those, we're going to put all those pieces of equipment in, there'll be alive and working to feed into the 2026 regulations. They will also be feeding into cars well before that.
"We've been focusing on our simulation tools, we need to be sharp, better at getting good answers to difficult questions more quickly. And I've experienced that in teams that I've worked at in the past. And that's one of our capability improvements.
