A project sponsor suggested a team forgo in-person demonstration meetings and just send the product...

The in-person demonstration meeting is crucial because it allows the team to directly engage with the product owner, ask clarifying questions, and immediately address any feedback or concerns. This fosters better communication, understanding, and collaboration between the team and the product owner. Being able to have a real-time conversation helps the team ensure they are building the right product, and it allows the product owner to provide nuanced feedback that might not be as clear through asynchronous communication (like sending a link).

The face-to-face interaction provides an opportunity for both parties to align more effectively on the product vision, avoid misunderstandings, and prevent misalignment on priorities, ultimately ensuring that the product being developed meets expectations.
