If you plan to launch a product or you are in the process of doing so, you should consider having a Product Manager, since their purpose is the successful operation of products or services, going from the moment they are created and launched on the market, until they disappear, obtaining as the maximum sales profit as possible.
At first, a PM may seem "not necessary," but as the product develops, you'll see how it transforms into an great element, being able:
To know the company's sector: customers, competition, opportunities, weaknesses, etc.
To identify a target audience, as well as their needs.
To know how to prioritize the demands of the clients.
To say NO to requests that don’t fit the conditions of the product.
To know how to solve the obstacles that emerge during the process.
And guide the production of the product in order to obtain a successful result.
Sometimes, there are products and services that seem like a great submission, but they don’t met the expectations, because they forget to understand the real needs of the clients.
