If you are a fan of David Allen’s Getting Things Done school of tasking and organising your life you will have noticed you are not particularly well catered for by way of webside services. For the uninitiated The Getting Things Done method rests on the principle that a person needs to move tasks out of the mind by recording them externally. That way, the mind is freed from the job of remembering everything that needs to be done, and can concentrate on actually performing those tasks. But GTD users could find things are looking up with online service Gtdagenda.

The Gtdagenda web site contains a comprehensive explanation of how to use the key components of the service including:

Goals: Goals are a tool to concentrate your effort and move you in a direction. Set goals in each of your life’s areas, along with the time lines you are commited to acomplish them by.

Projects: Action plans that map to one of your goals. Each completed project moves you closer to the completion of your goal.

Tasks and Next Actions: Break out each project into specific tasks (actionable items), and decide what the next action is going to be.

Contexts: Context is where or how a task is accomplished.

Checklists: Use checklists for your repeating/recurring tasks, things that you must handle weekly, monthly, quarterly, etc as well as action items that may be tied to a specific month (e.g. wax car every April and November). You can tie them to your goals. Consistent, daily action makes things happen.

Schedules: Schedules are tools for organizing your daily activities, with exact timings. Each activity can be linked to one of your existing projects and tasks.

Calendar: Use the included calendar to keep note of and remember your “set-in-stone” activities, that need to be done at certain dates.

You can set events, appointments, anniversaries, to-do’s and notes.

As with many services there is a wide range of buy-in options from the basic, free account which gives you give projects, contexts and checklists with three goals to the top of the range package that will cost you $50 a month for 15 users.
