The Prototype Stage of a Product Development Project

When we are talking about the prototype stage, the aim of the iteration is to understand to find a solution. Oftentimes, the customer doesn't really understand their own requirements. This could be a very fast iteration and also when we are later on on this get production ready type of development stage,. But the aim of this iteration is different. When you can reduce one cent in a product multiplied by 100 a year, this is a huge amount of money you can reduce at the end for the company.
