What are the implications for due dates and milestones when project slack is reapplied to the aggregated level?

What will be an ideal response?

Milestones are not used in the CCPM activity network; the only firm commitment is to the project delivery date. Team members responsible for individual activities may meet or miss deadlines and are much more likely to miss them if their usual safety margin has been taken from them for aggregation at the project level. The project organization must recognize the increased potential for missed deadlines so that finger pointing does not occur when deadlines are missed. Lack of milestones makes it difficult to work with suppliers and subcontractors. Flexibility must be built into this system so they can deliver materials or be on site at a moment's notice or be bound by early start times if their functions lie on the critical path.
