3 Fish thanks :-)

Answer 2

If you are talking about roles like product owner, project leader, developer, etc... The roles all require the person to know about the product and about programming. But a product owner rather describes tasks and talks them trough with the clients and the project leader sees to it that tasks get done in time and budget...
If that is not what you meant, please be more specific
