My company has a matrix organizational structure, and I would say that for the most part, it works really well and is an efficient way of running a project. One downside which Dr. Simon mentioned is that often the project managers and department heads have different goals and it results in a tug of war for resources. Also, the project managers have a difficult role because the project team does not report to them so technically they don’t have much control over their team. However, they are still ultimately responsible for the project and for meeting deadlines.
