I work in a functional based organization where I work with only other quality engineers. We coordinate with each other on our own projects and will only reach out to other organizational groups when our projects overlap our when we need a favor and have to coordinate how we can help each other out. I think Functional organization is the best because it keeps a steady structure to the group. Although having different mind sets being part of the group can be helpful, too many conflicting mindsets that all think in their own unique way can cause conflict and can create a long time period of adjusting and compromise. When working in a functional group everyone has the same mindset and knows what the rest of the group is trying to accomplish so it is easier to help out other team members and to coordinate. When working in a functional group it allows the team members to become masters in what they are working on rather than trying to learn and work on new projects that other people are trying to quickly teach you.
