Hello,
Currently we have all the epics estimated because our PO needed a forecast range for the end of the project, which seemed alright.
I was wondering about waste. Because at the beginning of a project, the more we estimate, the more we are in the cone of uncertainty, because we know less about the product.
So are there some logical tools/facilitating techniques to help reduce waste, by deciding how much we can estimate, before being reasonably sure that we are too much estimating/refining.
