TL; DR
A new river source heat pump in my home city of Nürnberg shows all the elements that must come together for a solution to be "DVFA" innovation.
In particular, this manages to be acceptable/ agreeable, which is where many innovation teams fall flat.
One might even go one step further and argue that "innovation" is less of the concern here. Instead, it's more about "company evolution," which is the ultimate outcome that we are going for anyway.
