I think the right thing to do is recognize the extremely high cost of communication and collaboration and weigh that against the benefit. Almost every manager I've known assumes that the cost of communication or collaboration is near zero while the cost of development is extremely high. Often, the cost of duplication development effort is lower than the cost of adding another communication and collaboration channel.
