Managing with the Web is - so far - still more of an art than a science. Much of it depends on human trust relationships and personal discipline that are not created and only insufficiently sustained by today's man-machine interfaces. Still, one thing is for sure: ManagingExpectations is a prerequesite of ManagingWithTheWeb. 

While ManagingExpectations can be done well locally without the means of the Web, the Web (the universe of hyperlinked information) is truly an enabling agent for managing expectations well in a distributed, loosely coupled system. If combined with telephone conferences and face-to-face meetings, it can actually work. But all the technology doesn't help him who doesn't manage expectations. (On the contrary?)

It is important to secure commitments from colleagues, e.g., for reviews
of documents. It does not suffice simply to ask (especially by sending email to a group of people hoping one will say "yes"). Negotiate review schedules. One way to encourage review is to schedule a one-hour teleconference with someone and walk through your document.

Other loose thoughts:
Email archives and paper trail.
Measuring what's cost-effective.
Social protocols.
Critical path.
You can say no (but cultural issues about doing so).
