Editorial commentary

Milestones are distinct from deliverables: a milestone is a point in time and a state of progress, while a deliverable is a tangible output. Horizon Europe formalises milestones in Annex 1 (the description of action) with named milestones, due dates, means of verification, and responsible WPs. Milestones often trigger management actions (e.g., go/no-go decisions, milestone-payment release, sponsor reviews). Missed milestones must be reported and may require remedial plans.
