Amicus Attorney and GTD
I don't use Amicus, but have used TimeMatters for a long time. I think that Wells Anderson (
www.activepractice.com ) is working on a GTD-based white paper showing how to setup/use GTD with TimeMatters. His site does have a more generalized paper on it currently re. GTD and practice management software.
I've been gradually incorporating GTD principles into my practice via TimeMatters over the last few months. However, one of the things that I've run into is trying to keep my personal GTD items separate from my professional life. This is mostly a coping mechanism that allows me to keep a safe distance between my own life and my client's lives and "issues" given that I practice primarily in divorce and family law. I really don't like to be reminded of Client X's problems when I'm working on, say, my garden and start to write down a new "personal-life" project that comes to mind! Unlike the original poster, my practice is highly adversarial/litigation based, with collaborative law cases few and far between, unfortunately.
I currently use TimeMatters solely for client GTD items and a Moleskine notebook for my personal GTD items. I keep a stack of blank 3 x 5 notecards in my car and in my Levenger wallet as my ubiquitous notetaking tool with Fisher Space Pen for easy jotting and then processing into the appropriate system (TimeMatters or notebook). I gave my Palm PDA to one of my partners about a month ago and don't miss it a bit.
TimeMatters uses a series of Classification Codes that can be customized easily, with one set for Events and one set for ToDo's. Both are easily customizable to "context" based lists and can be quickly filtered. I meet once a week (Monday 9 a.m.) with my legal assistant and my secretary to plan the upcoming week. For this meeting, I push my entire ToDo list from TimeMatters into an Excel spreadsheet. I then sort once by client and print it, and then once by date and print it. Based upon these two lists (which contain the same data in different sorted order), we plan the week ahead. Works pretty well, although I would like to also spend some time on Friday afternoons doing a more formal "Weekly Review" just by myself.
If you're using TimeMatters, I also highly recommend the "delegation system 2.0" setup that can be found at Tom Rowe's website:
