Usually a milestone is used as a project checkpoint to validate how the project is progressing and revalidate work. Milestones are also used as high-level snapshots for management to validate the progress of the project. In many cases there is a decision to be made at a milestone.
Polo xeral, os fitos son usados como ponto de control do proxecto para validar o progreso do proxecto e revalidar o traballo. Os fitos tamén son usados como instantáneas de alto nível para que os xestores validen a evolución do proxecto. En moitos casos os fitos sinalan a toma dunha decisión.
