Here’s what I was dealing with.</p> <ul> <li>Parent flags can’t depend on a flag in another project</li> <li>Segments can’t be shared across projects</li> <li>Visibility drops when one feature is spread over several projects</li> <li>Cross-team coordination gets expensive for the same reason</li> </ul> <p>Some of these have a simple fix. Removing the project scope from a segment (a reusable bundle of constraints that any strategy can reference) makes it available to every project. Others have none. A parent flag in one project simply cannot reference a child in another. I’m sharing some stats and what I learned along the way.</p>
