scheduled event for a predefined information exchange

[cited from ISO 19650-2:2018(en), 3.1.3.2]

Milestones act as signposts through the course of a project. An information delivery milestone is a point in time that signifies a change or stage in information development. Milestones are useful in project management because they show key deliverables and help to plan a further sequence of information exchange to ensure the right path in information exchange is being followed
