Which role on the delivery team is primarily responsible for building the product right?

The role primarily responsible for "building the product right" is the Architecture Owner. This individual has the critical task of overseeing the technical aspects of the project. They ensure that the architecture aligns with the overall vision and standards, guiding the technical direction, and making key architectural decisions. Their focus is on maintaining a high standard of technical quality and ensuring that the product is built in a sustainable and maintainable way.

While Team Members contribute significantly to the actual construction of the product, their duties center around executing tasks rather than the overarching architectural decisions. The Team Lead, while possibly influential in coordinating efforts, typically does not hold the specific responsibility for architectural integrity. The Product Owner, on the other hand, is primarily focused on the product's vision and ensuring that the right features are built to satisfy customer needs, but they do not usually engage directly in technical implementation details. Thus, the Architecture Owner stands out as the key role in ensuring that the product is built right from a technical standpoint, providing the guidance and frameworks that inform how the team will execute their work.
