Transforming finance with strategic modeling and analysis

A Product Manager is in charge of a product throughout its product lifecycle. That includes working out what customers want, helping the business to build the right product, and then supporting the business to sell it.
This Product Owner description is for the common understanding of the role in Agile Scrum. However, often, the role expands to cover other product management activities as well.
Release managers are responsible for the release management lifecycle, focusing on coordinating various aspects of production and projects into one integrated solution. They are responsible for ensuring that resources, timelines, and the overall quality of the process are all considered and accounted for.
