Even if the entire project team is in the same building, it's quite the challenge to manage the project. You can imagine how much more challenging it would be if the project team is scattered. The challenges of collaborating and sharing information is growing in magnitude as teams become more and more geographically and inter-company dispersed. For example, a Marketing project that involves external web site designers and PR teams, or a Professional Services project that includes dispersed teams and customer representatives, or an Engineering project that includes outsourced developers. All these projects require management of distributed project teams.
