How campaigns use milestones to track progress
Launch library · evergreen read

A milestone is a defined, checkable point along the way to a campaign's ultimate goal, useful because it breaks a long, sometimes vague journey into a series of smaller, more manageable checkpoints that can each be clearly assessed as they arrive during the campaign's ongoing life, rather than waiting until the very end.
Milestones give a campaign team and its supporters a concrete sense of whether things are on track, without needing to wait for the final outcome to know whether the overall effort is progressing roughly as intended over its full length from start to finish, which keeps morale steady along the way.
Well chosen milestones also create natural moments to pause and reassess strategy, since falling behind on a milestone is a useful early warning sign that something in the campaign's approach may need adjusting before too much further effort is committed to it unnecessarily, wasting resources that could go elsewhere.
