Because the plan is built once, in a separate tool, from a scope document that was already out of date when the project started. It is presented at kick-off and then maintained by whoever remembers, which is nobody after week three.
By the second month the plan says one thing, the task list says another, and the client is told a third. Nobody is lying — there are simply three records of the same project and no rule about which one wins.
A project opens from the won deal in Flow, carrying its scope, its agreed rates and its milestones. Phases group the work, dependencies set the order, and dates derive from the two rather than being typed twice.
Move a dependency and everything downstream moves with it. The Gantt, the roadmap, the backlog and the calendar are four views of one plan, not four documents to reconcile.
A slipped task shows as a slipped delivery date the moment it slips, because nothing sits between the two. The client-facing date and the internal date are the same date.
Re-planning stops being an event. It is what happens when somebody drags a task, and the margin in Books moves at the same time because the hours behind it moved.
It will not level resources for you. It shows who is over capacity and by how much; deciding what to drop is a judgement call with people and commitments behind it.
It also will not invent estimates. A phase with no estimated hours has no forecast date, and the plan says so rather than guessing.
Nothing here is an integration. Each line is two products reading the same record from different sides.

Fourteen days, every module, no card. Or half an hour with someone who will run it on your own records and tell you where it does not help.
