The product management team includes the individuals that are responsible for understanding that product features will bring the most benefit, and profitability to the organization. Once what is needed is understood, then it is necessary for the Product Management Team to create the requirements, in the form of features and User Stories. These will be needed before work can be done to implement the project.
