An blank is a model to test quality and costs before full-scale production

This doesn't make sense is there anything else u can give us

The correct answer would be Prototype.

Explanation:

A Prototype is a model to test the quality and costs before full scale production.

A prototype is basically a sample which is released early before the full scale production in order to test the concept, idea, design, or process of the product to be launched. It is done in order to secure oneself from being a provider of a poorly manufactured product. Prototype is used, tested and assessed for quality and cost analysis. If there comes any problem in the prototype, then this problem is resolved before the large scale manufacturing. We can take simple example of a chair and table, which is manufactured to see if the design and quality are good enough or not. If there needs any change, the alteration is done and then goes towards the manufacturing of items on a full scale production.

Prototyping is usually used in programming, web designing, semantics, electronics, etc.
