I would ask David Allen: Have you tried your GTD system in a company or for people that have to put out many fires each and every day?

I know that David says somewhere in the book that one shold not be spending time putting out fires all the time. But if I may explain why I would ask this: I read the GTD book recently and everything I have come across online. I have used kGTD for about 6 months too. The GTD system works great for me except for part of my job. I work in an ad agency with about 45 other people. Each and every day there are many fires (jobs) that have to put out because they are ordered by the clients in the morning or even after noon and they have to be delivered before six or the ads will not be published.

I see no easy way to implement GTD over such crazy work mania - there is no time to write any lists. Next action is more or less to do all the actions at the same time.

How ever GTD works quite good so far for the rest of my life. I am a designer here and also the computer guru (not my words though). I list of things to do, not to mention the things I want to do is a very long one. GTD is gives at least some fun handling all the small ideas and todos. I love to send a brilliant idea on something more to do with Quicksilver into the Inbox of kGTD!
