i want to track effort on unplanned work and ultimately categorise that work to understand what's taking time away from planned work. To help, for me unplanned work is any extra work that wasn't committed to in Sprint planning. It's not mis-estimation, but would be things such as having to fix a production bug or rebuild all environments as something killed them. It's generally work that has to be done, but wasn't known at planning. Effort spent here ultimately takes away from effort working on planned work
