The team is documenting all the checkpoints along the way that might indicate delays on critical deliverables, which is an example of risk triggers. Risk triggers are events or conditions that indicate a risk may be about to occur or has already occurred, helping the project team to monitor and respond to risks effectively.
Risk triggers are indicators or warning signs that a risk event is about to occur or has occurred. They help to monitor the status of risks and initiate risk responses when needed. Documenting risk triggers is part of the Plan Risk Responses process, which aims to develop options and actions to enhance opportunities and reduce threats to project objectives.
