You are in a project meeting where your immediate manager and the Department Head are discussing a certain aspect of the project. The situation and problems are complex and certain areas are even beyond your understanding but it looks like there are only 2 possible options at this point in time. It becomes clear to you that the two of them have very different and strong opinions about which decision and direction should be appropriate to take. Each has his own views, with a good mix of strong arguments for his decision, with identified limitations, risks and potential consequences. They have turned to you to ask you for your opinion and to choose which one you will support. What do you do?
