The official GTD definition has been changed recently. Here is the current definition from http://www.davidco.com/what_is_gtd.php:

Piloting a productivity seminar for a thousand managers at Lockheed in 1983, David has continued to test and refine the techniques and principles we now know as GTD - a powerful method to manage commitments, information, and communication. This pioneering and proven system is the result of those twenty plus years of David's consulting, private coaching and organizational programs with over a half million people internationally. GTD has well earned its recognition as the gold standard in personal management and productivity for many of the world's best and brightest people and companies.
Sophisticated without being confining, the subtle effectiveness of GTD lies in its radically common sense notion that with a complete and current inventory of all your commitments , organized and reviewed in a systematic way, you can focus clearly, view your world from optimal angles and make trusted choices about what to do (and not do) at any moment. GTD embodies an easy, step-by-step and highly efficient method for achieving this relaxed , productive state. It includes:
Implementing GTD alleviates the feeling of overwhelm, instills confidence, and releases a flood of creative energy. It provides structure without constraint, managing details with maximum flexibility. The system rigorously adheres to the core principles of productivity, while allowing tremendous freedom in the "how." The only "right" way to do GTD is getting meaningful things done with truly the least amount of invested attention and energy. Coaching thousands of people, where they work, about their work, has informed the GTD method with the best practices of how to work (and live), in that most efficient and productive way.
- Capturing anything and everything that has your attention
- Defining actionable things discretely into outcomes and concrete next steps
- Organizing reminders and information in the most streamlined way, in appropriate categories, based on how and when you need to access them
- Keeping current and "on your game" with appropriately frequent reviews of the six horizons of your commitments (purpose, vision, goals, areas of focus, projects, and actions)
GTD's simplicity, flexibility, and immediacy are its attraction. Its ability to enliven, enlighten, and empower is its magic. What, indeed, is GTD? More than meets the eye...
