Software Development Life Cycle

Product Owner (PO)

A core role in Scrum software development methodology, every team has one. Is the voice of the customer, assessing business value of product requirements. Likely the visionary leader and people manager of the team. This role may have other names depending on the organization, such as Single Threaded Leader at Amazon, or Product Engineering Lead at Square.

Product Manager (PM)

Generally the business person on a development team, functionally close to the Product Owner. Represents customer and market needs, ensuring those requirements are met as software is developed. This is a role in the team, not a “people manager” of the team.

Product roadmap is maintained by the Product Owner, although sections of it are given to team leads for their share of the project.


Minimum viable product. The smallest product you can put in the marketplace to validate need, demonstrate core value and begin getting feedback from customers. Examples vary from a simple email sign-up form to a minimally-functional website.


Prioritized list of customer-centric requirements in the form of user stories or jobs to be done. It’s the formal name for a comprehensive TODO list.
