I too have been a part of a Matrix organization. I would agree with the posts above that it does get confusing sometimes. I had a functional manager and a reporting manager for the same project. However, the things were made very clear to me in the beginning of what the purpose is of both the managers. I would report to the functional manager on daily tasks and meetings. However, we would present as a team to reporting manager once a week. The reporting manager was more of ‘go’ to any new ideas or major modifications we needs to make.
