Advice on creating a roadmap with your team

Hello everyone

I’m a newly promoted leader for a small team of specialist working with marketing and e-commerce.

I’m looking for advices on how to create a roadmap for future projects in collaboration with the rest of my team.

As I see it, it doesn’t make sense to have specialists on your team and not let them be a part of setting a course for the ship.

So how do I do this the best way?
