Project Deliverables refer to a measurable and auditable output which is expected to be produced or gained upon successful accomplishment of a related project or its certain part (phase, stage, activity). They can be either tangible or intangible results of the project development process and often specify features and functions of project product.
Deliverables of a project serve as the major characteristic of project product. They are identified and defined at the very beginning of the project through communicating with the customer and sponsor. Both stakeholders need to jointly work with each other to identify what desired outcome their project should produce.
Project deliverables are often referred as one of the key components of project scope. Along with project requirements and boundaries, they identify overall scope and aim to reach an agreement with the customer and sponsor about the outcome the project needs to produce. Initial expectations of the customer will serve as a foundation for defining deliverable acceptance criteria which are used at project completion to approve or reject project deliverables.
