You should do vision casting
People do not follow plans, they follow pictures. Describe the future vividly enough that others can see themselves in it.
Vision casting is describing a future so clearly that other people can see it, want it and find their place in it.
Plans and roadmaps tell people what to do. A vision tells them why it matters and what it will feel like when it works. “We will migrate to a modular architecture in Q3” informs. “Six months from now, any team can ship a feature in a week without waiting on anyone” moves people.
You do not need a title to do this. An engineer who can describe what the codebase, the product or the team could become is doing leadership work, whatever the org chart says. Good technical decisions often win adoption not because they are correct, but because someone makes the future they enable easy to picture.
Try this
Describe your current project as it will be one year from now, in five sentences and without a single technical term. Share it with one person and ask what they see.
