It can be easy to underestimate the power of advertising campaigns, but it's important to know that in order to purchase a product, there is a range of ways of informing people of its existence: newspapers, TV, social media… A product manager will make sure that the company is creating consumer awareness in the right way and thus make sure people will be willing to buy the product.
The main goal of a Product Manager is to ensure that the product developed by the company supports the company's long term strategy and goals. To do so, the Product Manager will carry out various tasks throughout the product lifecycle: collecting and prioritizing product requirements, defining a product vision and making sure the engineering and marketing and sales team are developing a product that will drive revenues and company growth.
To become a Product Manager, you require a Bachelor's degree. An employer will also want to see demonstrated success in the launch of excellent products, excellent written and spoken communication skills, technical background and an ability to work in cross-functional teams.
