Final answer:
A 'prototype' is a preliminary model of a product used to test and refine its functionality before full production. It serves as a base for further development and testing to enhance and stabilize the product.
Step-by-step explanation:
The blank in the sentence should be filled with the term prototype. A prototype is a trial working model of a product that is used to test various aspects of its design, including its core functionality. It is an essential part of the development process as it helps in identifying potential problems before the product goes into full production.
By testing a prototype, developers can make necessary adjustments, enhance functionality, and ensure stability before finalizing the product. This iterative process of prototyping allows for refinement and expansion of the product's capabilities to meet the desired outcomes.
A prototype is a stable, functioning product that incorporates the core functionality of the product and is built with the intention of expanding functionality before releasing to full production. It can be considered as a trial working model of a design that is built to test design decisions and identify potential problems.
