In GTD, how do you handle delegating an action if the act of delegating itself cannot be accomplished right when you are processing your inbox, and in less than two minutes?
e.g. "summarize the last marketing report", which I want to delegate to Mike. I can delegate by email, but since I want some specific breakdowns of the data, writing the email will take me longer than two minutes.
Going by the principles of GTD, I now create an action "write Email to Mike with request for summary of marketing report". I add this to the next actions list. The delegated action itself, "summarize the last marketing report" cannot yet go onto the 'waiting for' for list, since I'm not actually waiting for the result (yet).
Where do I store this action in the meantime, until I've written the email? Are there any systems out there that model this well? That handle dependencies of this sort well?
