I would agree with you that face to face meeting is more productive and effective when it comes to time management and quick respond. However, Form my work experience. It is always hard to schedule a meeting that can fit everyone’s calendar. Also, Sometimes when you work on a big project, you outsource other company to complete part of the tasks for you or to provide you with input. So, not everything is done in-house. I think the method of class helps us to improve E-communication skills and time management besides the project management concepts. Sometimes the barriers are not only about money but bad communication and follow up on action items can cause a very high risk to the project.
