We have several ways of estimating potential roadmap items:
Provisional - T-shirt size not based on much info
High level - someone has sat down and thought about it for half an hour based on some assumptions
Detailed - a BA has spent a decent amount of time thinking about it
It would be useful to be able to record this on the feature somewhere. Sometimes I'm given a range, so it would be nice to have an upper and lower estimate field but appreciate this will add complexity to capacity planning.
Thank you for your idea. One way to handle this currently would be by adding a custom field. This field would not have any impact on capacity planning, but it would provide additional context regarding the certainty of the estimate given.
