MILESTONES
Put key events into the project plan.
Use numeric zero duration on ordinary leaf tasks for events such as project start, order effectiveness or delivery confirmation, connected to predecessors, both schedules and the Gantt chart.
- Maintain dates and relationships separately in Baseline and Re-schedule; Gantt diamonds identify milestones.
- Planned due dates and actual achievement remain separate, with weights set under project measurement rules.
VDR MAINTENANCE
Change the current list. Keep the history.
During execution, modify document numbers or titles, add documents and cancel documents in one maintenance workflow. Check the complete batch before confirming changes.
- Changes link VDR, Planner, PC and registers; recorded former numbers can help identify incoming documents using old numbers.
- Past correspondence and issued transmittals remain part of the record. Review plans, weights and current progress after maintenance.
