Here's the scenario: The main point of contact was fairly active up until the project came close to the launch date. At that point, the client started to miss the dates for requirements that were needed for the next set of tasks.
What is the process for managing the schedule in this case?
Say, to do X, we need Y. Client needs to provide Y on Jan 15.
What does the PM do on Jan 16 assuming Y was not provided the day earlier?
Going forward, would communication issues like these go into the Risk Register?
