We have a structure of projects that describes basic parts of our SaaS product. Now, most of Epics are clearly heading to the specific value stream, so finding the correct project is relatively easy and ability to have an issues across the projects makes the visibility of such initiatives really great.
What I struggle with is how to assign an initiative that adds a small functionality to all projects we have, imagine adding Intercom to all parts of product. How would you structure this? A separate project sounds like too much effort (as the task itself is small). Having some "platform initiatives" project?
