Agile - Reporting "dead" tasks
I am new to Smartsheet and agile and am looking for best practices. If you plan a task for the sprint and it suddenly is stopped or placed on hold, what is the proper way to record this? Should you simply delete the task from that week's sprint? Perhaps add a status called "Dead/On Hold"? When it's outside of your team's control, how do you account for that?
I appreciate anyone's insight.
