Project Schedule Checklist

This checklist helps ensuring that the project schedule covers most things that impact it, apart from the tasks themselves.
1. Tasks and subtasks, of course, with start and end dates and dependencies amongst themselves, and resources assigned to them.
2. Team Meetings
3. Document Reviews
4. Per Milestone Buffer
5. Internal and External milestones noted separately
6. All approvals from customer noted individually, especially the one for Acceptance Test Plan
7. All Vendor deliverables noted separately.

Some of these are included depending on the target audience of the schedule, e.g. internal milestones may not be part of the schedule that is exposed to the customer.
