Generally, the technology partner will assign a dedicated project manager if you outsource your software development project. The project manager will handle daily operations and act as a bridge between the new technology partner and the product owner.
As a product owner, you don’t need to micromanage daily activities. However, if you have any essential inputs or concerns, you can covey those to the project manager. The project manager will stay in touch with you throughout the project management process and make sure the deliverables at every step match your expectations.
