Agile plans may show features (or sets of features) and their order and their
dependencies, and are likely to have been created collaboratively by those who will carry out the planned work. Agile plans tend to be informal or low-tech at the delivery team level and this can be highly effective even though they may be no more than to-do lists or
backlogs.
Product- based planning can still be used at all levels of the project (including product delivery).
