Product management starts from when a product is merely just an idea and continues all the way through the lifecycle of a product, including when the product arrives in the customer's home. A product manager drives the strategy for a product or group of products. Product managers are often responsible for educating the executive staff on the need for the product in the market.
However, one thing is consistent, the product manager represents the customers' needs. The product manager is responsible for bringing together the technology, business, and users. The technology includes the actual product itself.
The business represents those that have the ability to bring the product to market, and the user is the customer that has a desire for this product. The product manager is the only person in the company other than the Chief Executive who has a focus on bringing all the aspects of a product together.
That’s because it doesn’t fit any of the traditional roles you may already be familiar with: business strategy, design, marketing, and engineering. Product management is the voice of the competitive market inside the business venture.
The market in the product management include the customers, and non-customers, buyers and users at companies in target market segments. To be simple, the product management is an interdisciplinary role that reaches across teams to design, bring better products to the market, set your business plan, and marketing.
