Really Simple Syndication (RSS), which notify blogophiles about new posts to their favorite blogs, could allow law departments, I suspect, to know immediately whenever a law firm timekeeper enters time to one of the law departments’ matters.
That a law department would want to have such up-to-the-second raw data, I doubt. Perhaps something meatier, like a weekly or fortnightly total of time, or data that compares the actual time to the budget, would be palatable. Another possible use of RSS feeds would be on a major document discovery effort; where the feed could tell how many documents were processed. More generally, RSS could transform law department management where there is any kind of information that needs to be rapidly updated.
