Transition from technology-led, to product-led

My company has a very strong research and technology focussed team, but product thinking hasn't always been valued in the past. Thankfully the exec team is aware of this and is supportive of a shift to product led approach.

Specific challenges I see in this situation are: 1) Very specialist engineers and technologists are enthusiastic about building technology they love (which is great), but it's not always connected to a customer or business goal 2) In the past, lack of requirements was a blocker to start building, so there are some negative connotations around gathering requirements properly now 3) Lack of standardised tools for managing work / intake. Jira is supposed to be used but update varies widely across teams 4) Teams are not currently very delivery focussed (people rarely talk about dates), making release planning, launches, and marketing difficult 5) Lack of focus - current products are broadly spread across a range of applications, but none of them have advanced to a release ready state despite fairly significant development resources

(As I've typed these out, I'm aware they basically translate to every day PM challenges 😅)

Has anyone led a business through this transition before? Interested in any advice from strategy through to day to day tactics.

Thanks in advance 🙏
