Final answer:
A project deliverable is a tangible, measurable and specific outcome that a project promises to provide upon its completion.
Step-by-step explanation:
A project deliverable is a specific outcome or result, often in the form of a product, service, or documentation, that is produced as part of a project. It is what the project promises to provide upon completion. Deliverables can vary in complexity, size, and type, ranging from large-scale physical structures to digital files or reports. The key characteristic of a deliverable is that it is tangible, measurable, and specific, enabling project stakeholders to see the progress of the project as deliverables are completed.
