A well-defined feature/mechanic list which differs from a Scope of WorkSimilar to a Milestone, a descriptive set of goals for a phase of development... by being paired with deliverable(s). The more defined, the better, things not present aren’t likely to be in the deliverableRefers to the "physical" items which can be delivered, usually as part of a milestone, to a client. This should include at least one file of the types: source code, art assets, documents, or executable binaries; though full games fall under this label as well..... Decent examples include feature/title updates – or the Beta phase of a game.
