You can't always give developers a list of features and wait until they think it's done. Management should give developers a feature/bug list, developers should then estimate the items on that list. Then management can pick a subset of items for the next release. If there are features that really need to be done and there isn't time, management can negotiate the scope or design of the feature with developers (but never the estimates). Sometimes it's better to ship a simpler feature now, than wait to ship a feature that's "right".
