Release planning refers to planning activities used to estimate when software will be released into product use. Activities include projecting the level of effort in terms of the number of iterations that will be necessary to deliver the desired features. This is typically done by extrapolating the development team’s performance on the basis of its velocity. Release planning brings together all parties that have a stake in the outcome and have some kind of delivery responsibility to achieve the release to produce a viable release plan. Release planning is one of the five levels of planning.
SAFe defines a similar term, Release On Demand, which is the process that deploys new functionality into production and releases it immediately or incrementally to customers based on demand.
