Answer:
Market testing
Step-by-step explanation:
Market testing is the phase in a product development where the market is tested for how well the potential new product will be accepted before it is finally produced in a large volume.
The prototype version of this product can be used for this purpose alongside a potentially suitable advertisement method .
The response of the market to this practice suggest the next line action for the producer , whether to go on with the production or make some improvement or totally abort the production plan
