I work in service management and am challenged to keep GTD implemented. Most of my work is stuff coming at me from customers and staff--all wanting attention at once. Very little is self-directed.
Most of my work involves taking care of (or getting field personnel to take care of) customer needs the same day or next day--very short turn-arounds. 100's of customers each week--open issue, dispatch techs, handle phone issues, close issue, prepare item to be billed, handle disputes, etc....
I find it so hard to use GTD because by the time I put a context on an item (like @agenda) or record it as a call to be made one of two things have happened--one, I got interrupted to take care of the next issue (yes, that quickly), or two--the finding of the item later in it's proper context is slower than just paging back through a notepad (the records/scribbles info as it comes it) and dealing with it that way.
Does anyone find that GTD just doesn't work for their type of work? (Or, and this is maybe very likely, am I just attempting to justify my multiple failed attempts to implement GTD?)
