What is a deliverable?

In his What Is a Deliverable in Project Management?, Kermit Burley, of Demand Media, writes: „In project management, a deliverable is a product or service that is given to your client. A deliverable usually has a due date and is tangible, measurable and specific.

A deliverable can be given to either an external or internal customer and satisfies a milestone or due date that is created and produced in the project plan. A deliverable can be a software product, a design document, a training program or other asset that is required by the project plan.“
