Why is it important for a marketing manager to critically analyze all the stages of product development process before launching a new product?

The marketing manager is responsible for outlining sales strategies for the product. It is the person who knows best who that product is intended for, the type of consumer it will buy. It is important for this manager to be aware of product processes to understand the product perfectly and to map out potential flaws that could compromise product marketing. This is extremely important because if there is a serious failure the product may no longer be purchased or may be returned in bulk by customers. Then, from the full knowledge of the product, the manager will have the confidence to create advertising methods to stimulate the product's target audience in order to maximize the company's sales and revenue.
