Final answer:
The work product becomes a deliverable after being reviewed and agreed upon. Deliverables are the end products or services resulting from a project. The process involves prototyping, testing, and refining the product to ensure quality and adherence to requirements.
Step-by-step explanation:
Once the work product has been reviewed and agreed upon, it becomes a deliverable. A deliverable is a term used in project management to describe a tangible or intangible product or service that is produced as a result of a project and is intended to be delivered to a customer or sponsor. A prototype is a preliminary model of a design that is built to test design decisions and identify potential problems. The engineering team may refine this prototype to ensure it meets constraints and criteria and only then does the prototype evolve into a deliverable. This process typically includes prototype, test, and refine stages to evaluate the quality of a design and make necessary adjustments before finalizing the product.
