It is important to understand the other individuals point of view. There can be a multitude of reasons why the other individual is unresponsive or willing to have sit down meetings. Generally, if you are able to form a relationship with the individual in industry, they are more willing to listen and be of help. That open line of communication is important in any project. Once that has been established, it should be a lot easier to have the individuals who were not compliant before be a little more responsive to the meeting requests. Coming from a domineering point view does not always work out well from a managerial standpoint and in industry with project managers I have worked with, it is the ones that speak eye to eye with me and understand me on a personal level are the ones that I tend to be more responsive to and prioritize those tasks over others.
