Hi there! I'm helping manage a program of four "advisors", all of whom are working on independent projects.
We have multiple (Asana) boards: one for program-level tasks (documentation, and separate project-level boards for each advisor.
The team only reports on program-level work during our ceremonies, because each project has no impact on other advisors, and is of no concern to the other advisors. (The advisors and I have one-on-one meetings to keep track of their project-level work.)
